Replacement-part availability varies by model. The official store does not currently offer most small replacement parts for individual sale, although selected lens hoods may be available for certain models. Please contact Viltrox Support with the exact product model and purchase details so we can confirm current availability.

No. Air series lenses are made for specific mounts. Depending on the lens model, versions may be available for Sony E-mount, Nikon Z-mount, or Fujifilm X-mount. Always match both the lens mount and your exact camera model before ordering.

The AF 40mm F2.5 Z is a compact autofocus prime designed for Nikon Z-mount full-frame mirrorless cameras. Its 40mm focal length, F2.5 aperture, compact size, and autofocus design make it suitable for everyday, travel, street, and general photography.

Use a blower first for loose dust, then a clean, soft microfiber cloth for the lens surface. Avoid harsh chemicals and rough materials. Keep the front and rear electronic contacts clean and dry, and store the lens in a cool, dry place when not in use.

Viltrox provides a 1-year limited warranty for products manufactured and sold by Viltrox, covering eligible defects that occur under normal use. Warranty eligibility, shipping responsibility, exclusions, and service procedures are subject to the current warranty terms. Please contact Viltrox Support before sending any product for service.

The front element has a water- and stain-resistant coating that provides some protection against light moisture and dust. It is not a fully weather-sealed lens, so avoid exposing it to heavy rain, water, or harsh environments.

Use the update method specified for your exact lens model. Download the correct firmware or software from the official Viltrox Download Center, extract the package when required, and follow the model-specific update guide. Use a data-capable cable and keep the connection stable until the update is complete. Do not install firmware intended for another model or mount.

Open the official Download Center or the relevant product page, select the exact monitor model, and download the available manual or firmware files. If a manual is not listed for your model, contact Viltrox Support with the model name.

Confirm that both the camera and lens are set for autofocus, then power off the camera and reinstall the lens. Make sure the electronic contacts are clean and dry, and check the recommended camera and lens firmware for your combination. Test again in good light using a simple focus mode. If the issue continues, contact Viltrox Support with the camera model, lens model, firmware versions, serial number, purchase information, and a short video showing the problem.

The 33mm F1.4 design uses 10 elements in 9 groups, including an ED element and a high-refractive-index element to help control aberrations and maintain image quality.

The Viltrox AF 56mm F1.7 is approximately 170g, giving it a compact and lightweight form for travel and everyday shooting. Product specifications can vary slightly by mount or production revision, so check the product page for the exact version you plan to buy.

The AF 23mm F1.4 combines a bright F1.4 aperture with STM autofocus and an optical design intended for compact APS-C systems. Some versions include a firmware-update port. Check the product page for mount-specific specifications and compatibility.

The lens is approximately Φ65 × 72 mm and around 270 g, making it relatively compact for an F1.4 autofocus prime. Exact specifications should be confirmed on the page for your mount version.

Import duties, VAT, customs charges, or carrier handling fees may apply depending on the destination, fulfillment location, shipping method, and local regulations. Check the carrier or customs notice carefully before making payment. If you need help confirming a charge related to an official Viltrox order, contact Viltrox Support with your order number and tracking number.

The DC-550 Pro provides additional monitoring tools, including more histogram and waveform display options, while both models offer 1200 cd/m² brightness and active cooling. Specifications can change by product revision, so please compare the current product pages before purchase.

The S05 is a compact RGB LED light for photography, video, vlogging, and live content. It offers adjustable brightness and color controls, high color rendering, and multiple scene-lighting effects in a portable form.

The EF-E5 supports autofocus and provides selectable focusing behavior for compatible camera/lens combinations. It also supports firmware updates through its USB port. Compatibility depends on the exact camera body, lens, adapter version, and firmware.

Disconnect the product from the camera, use a known data-capable USB cable, and connect it directly to a computer USB port rather than through a hub. Confirm that you are following the update method for the exact product model. If the device is still not detected, try another cable, USB port, or computer. If the issue remains, contact Viltrox Support with the model, serial number, current firmware if known, and a photo or video of the connection.

The files shown during an update can vary by product and update method. The absence of DeviceInformation.txt does not by itself confirm a hardware fault. Do not downgrade or repeatedly reinstall firmware to match another model's instructions. Check the guide for your exact product, and contact Viltrox Support if the current firmware version cannot be verified.

A temporary disconnect can be part of the update process on some products while the firmware is being installed. Keep the cable connected and allow the process to finish. When the device reconnects, verify the firmware version using the method provided for your model. If the device does not return or no longer functions normally, contact Viltrox Support before attempting another update.

Always use the firmware package listed for your exact product model and mount. Extract the downloaded package before updating when instructed, and install only the file identified in the model-specific guide. File extensions and update methods can vary by product. Never use a similarly named firmware file from another Viltrox product.

Do not downgrade firmware unless Viltrox Support has confirmed that a rollback is appropriate for your exact product and issue. Installing an incompatible or older firmware file can cause additional problems. If you need help, provide the product model, current firmware version, previous version if known, connected camera or lens, and a description of the issue.

Do not downgrade the product solely because its displayed firmware version differs from a version currently listed online. If the product is working normally, leave the firmware unchanged and contact Viltrox Support if you need the version confirmed. Only install firmware that is explicitly provided for your exact model and revision.

Power off the camera, remove and reinstall the lens, and make sure the electronic contacts are clean and dry. Check whether Viltrox provides a lens firmware update for your exact model and camera combination. If the issue began immediately after the camera update, contact Viltrox Support with the camera model and firmware version, lens model and firmware version, and a short video showing the behavior.

Before updating Nikon Z camera firmware, remove all third-party lenses and lens adapters, including Viltrox products. Complete the camera firmware update first, then reattach the lens or adapter after the camera has restarted normally. If you experience an issue after a camera update, contact Viltrox Support with the camera and lens or adapter firmware versions.

No. App-based firmware updating is available only for supported models. Other lenses may use Viltrox PC software or a model-specific file-transfer method. Check the current Download Center and update guide for your exact lens before beginning an update.

No. Use a cable that supports data transfer. A charging-only cable can power the device without allowing the computer to detect the update drive. If detection is intermittent, try a short known-good data cable and connect directly to the computer rather than through a hub.

Confirm the exact monitor model and, where applicable, hardware revision. Download only the firmware provided for that model, extract the package as instructed, use the required storage format, and keep power stable throughout the update. Never install firmware from a different or similarly named monitor model.

Use the firmware page for the exact adapter model and follow the official update instructions. Use a reliable data cable and keep the adapter connected until the update is complete. If autofocus or communication changes after an update, do not install an older firmware file on your own; contact Viltrox Support with the adapter, camera, lens, and firmware versions.

Match the camera mount first, then confirm the exact body on the product compatibility information when available. Sony E, Nikon Z, Fujifilm X, Canon RF/M, Leica L, and other mounts are physically and electronically different. A similar focal length does not mean a lens version can be used across mounts.

Not always. Autofocus speed and available focus functions depend partly on the camera’s AF system, body firmware, and communication protocol. Older bodies may focus more slowly or support fewer AF features even when the lens mounts and operates correctly.

Turn the camera off, remove and reseat the lens, inspect and gently clean the electronic contacts, restart the camera, and confirm the lens is the correct mount. Update firmware when an applicable update exists. If possible, cross-test the lens on another compatible body or another lens on the same body to isolate the cause.

Test in good light using AF-S and a single focus area, check that the camera is not in manual focus, reseat the lens, clean contacts, and confirm both lens and body firmware. Then test different focus modes and subjects. If the behavior is repeatable, record a short video showing the camera screen and settings for support.

Power off the camera, reseat the lens, clean the electronic contacts, and confirm you are using the correct mount version. Check both camera and lens firmware. If the issue began after a body firmware update, contact Viltrox Support and provide the exact body version, lens version, and a short video of the symptom.

Check the full chain rather than only the adapter: camera body, adapter, lens, contacts, and firmware. Reseat all parts, clean contacts, test the lens directly on a native body if available, and test another known-compatible lens on the adapter. Third-party lens protocols can vary, so provide the exact lens model when requesting compatibility help.

Not necessarily. A firmware release note may refer to a specific function, such as communication or autofocus, rather than every feature in a camera, lens, adapter, gimbal, or accessory combination. Confirm compatibility for the complete setup and the function you need before purchase or professional use.

Use the dedicated DC-T1 Smartphone Compatibility Guide and search for your phone model. DC-T1 requires compatible wired video output, typically USB-C DisplayPort Alt Mode. Compatibility can also vary with operating-system version, cable specification, adapter, and regional phone variant.

Not necessarily. The compatibility table is non-exhaustive and not every phone can be individually tested. If your model is not listed, confirm with the phone manufacturer whether the USB-C port supports DisplayPort Alt Mode or wired video output. A USB-C connector alone does not guarantee video output.

Use a full-featured USB-C cable that supports both data and video transmission. A charging-only or USB 2.0 cable may not provide the video and audio path required for DC-T1. Cable quality, adapters, and phone configuration can also affect the connection.

On iPhone, open Settings → Accessibility → Touch → AssistiveTouch and turn on AssistiveTouch. If touch operation becomes unresponsive, open the app switcher and try again. For additional iPhone display notes, refer to the current DC-T1 Smartphone Compatibility Guide.

Some HUAWEI phones display a wired-projection prompt after connection. If the prompt was dismissed, disconnect and reconnect the cable. If the phone and DC-T1 show different content, open the active projection control and switch to mirror mode.

Yes. Some Samsung phones may require an audio option to be enabled after connection, and charging or sleep behavior can vary when power and audio are connected at the same time. Follow the current Samsung-specific instructions in the DC-T1 Smartphone Compatibility Guide for your setup.

No. The DC-T1 port is rated at 5V, and phone power output is approximately 3W. Do not use the DC-T1 port to power high-demand charging devices.

Confirm the camera is actually outputting video over HDMI/USB-C as required, verify the correct input is selected, reseat the cable, and test another known-good cable. Check the camera output resolution/frame-rate settings and cross-test the monitor with another source if possible. Note that display output and camera-control functions may use different connections.

Not necessarily. Image display, monitor menus, and camera-control communication are separate functions. Confirm the control cable/connection type, camera control support, monitor firmware, and camera settings. Send the exact camera and monitor models plus connection diagram if support is needed.

For monitor models that support LUT import, use the file format and storage method specified by that model. Common troubleshooting includes using a compatible SD card formatted as required, placing the .cube file in the required location rather than inside extra folders, and testing a simple known-good LUT file. Do not assume every monitor model uses identical card limits or folder rules.

Verify the battery or external-power source meets the monitor’s required voltage/power specification, reseat the battery/cable, and test another known-good power source if available. If there is still no response, provide the monitor model, power method, battery/adapter model, serial number, and a video to support.

Choose the dedicated version for your camera system: Z1 Pro C for Canon, N for Nikon, S for Sony, or F for Fujifilm. Physical hot-shoe fit alone does not guarantee TTL, HSS, or full electronic communication.

Check the battery level, make sure the flash is fully seated and locked in the hot shoe, confirm you bought the version for your camera brand, and verify the camera has external flash enabled. Many cameras disable flash in silent/electronic-shutter modes, so test with a compatible mechanical shutter mode.

This usually points to a synchronization mismatch. High-Speed Sync must be supported and enabled on both the camera and the Z1 Pro. If only one side is in HSS, black bands can appear. As a test, lower the shutter speed to the camera’s normal flash sync range or re-enable HSS on both devices.

The Z1 Pro line is designed around dedicated Canon, Nikon, Sony, and Fujifilm versions. Panasonic Lumix FZ300 is not listed as a supported TTL/HSS system for the Z1 Pro, so full electronic compatibility should not be expected. Please choose a flash solution that is specifically verified for your camera.

Provide the exact camera model, exact adapter model, exact lens model, all firmware versions, and what the camera displays. Reseat and clean contacts, restart the camera, and cross-test with another compatible lens/body if possible. Compatibility can vary by individual third-party lens firmware and protocol.

Do not roll back on your own. First confirm the exact adapter firmware, camera body, lens model, and symptom. Viltrox support may recommend a specific recovery or rollback only after checking the combination. Using an incorrect older file can make the problem worse.

For orders purchased directly from the official Viltrox website, contact Viltrox Support. Keep your proof of purchase and seller information for any service request.

Check the latest carrier tracking first. International shipments can experience customs clearance, handover, weather, or local-delivery delays. If there has been no meaningful tracking update for an unusual period, contact Viltrox Support with your order number and tracking number so the shipment can be reviewed.

Orders can sometimes be split into multiple packages because products ship from different warehouses or become available at different times. Check whether more than one tracking number was issued. If an item is missing and no second shipment is shown, contact Viltrox Support with the order number.

Replacement availability depends on the product model and purchase channel. The official store does not currently offer most small replacement parts for individual sale. Contact Viltrox Support with the exact model and, for official-store purchases, your order number. For third-party purchases, please contact the original seller or platform first.

Take a photo of everything received, the product box, shipping label, and package contents, then contact the seller with the order number and missing item. For official Viltrox website orders, contact Viltrox support; for third-party orders, contact the original seller/platform.

Use the official Viltrox Download Center and select the exact product category, model, mount, and hardware revision when applicable. Do not install firmware shared for another product, even if the model name or version number looks similar.

Check both the product page and the Support / User Guide areas. If the manual is still unavailable, contact Viltrox Support with the exact model name and a photo of the product label so the correct document can be identified.

Use the official Flash Guide area for model-specific setup, TTL/HSS instructions, camera-brand notes, and troubleshooting. Guides are available for products including the Vintage Z1 Pro and Z2.

Launch and restock dates are confirmed only when officially published. Check the current product page, New Products section, and official Viltrox channels for the latest availability. If a date has not been announced, Viltrox Support may not be able to provide a guaranteed release or restock date.

Specifications, firmware, bundles, and compatibility information can change by model revision, mount, region, or software version. For current purchase and setup decisions, use the latest official product page, manual, compatibility guide, and Download Center information.

Regional storefront prices may reflect local pricing, taxes, currency conversion, payment processing, and region-specific promotions. The amount shown for your selected region and the final checkout total are the relevant prices for your order. If you believe a displayed price is incorrect, contact Viltrox Support with screenshots of the product page and checkout.

Tourist tax-refund eligibility is determined by local tax rules and the retailer that issued the invoice. Viltrox cannot guarantee eligibility for a local tax-refund program. Before purchasing from a physical retailer, confirm directly with that retailer whether tax-refund documentation is available and what requirements apply.

Shipping availability depends on the destination and product. Add the item to your cart and enter the delivery country or region and postal code at checkout to see the current shipping options. If no option appears, contact Viltrox Support with the product model and destination for assistance.

When regional inventory is available, some European orders are fulfilled from an EU warehouse. The actual fulfillment location depends on the product, destination, and stock availability. Your shipping confirmation and carrier tracking provide the best information for a specific order.

Discount and reward codes are normally applied during checkout. If you forgot to use a code, contact Viltrox Support as soon as possible with the order number and code. Any adjustment, cancellation, or re-order option depends on the order status and the promotion terms.

Special discount programs may vary by region and campaign. Please check the current official-store promotions and checkout offers. If a dedicated program is not shown, contact Viltrox Support before ordering to ask whether an eligible offer is currently available.

Use the dates and terms shown on the official promotion banner, campaign page, product page, or checkout. Promotion periods, eligible products, and inventory can change by campaign. If no end date is published, availability should not be assumed beyond the current offer.

Local availability varies by country and product. Check established camera retailers in your region or contact Viltrox Support with your country or city and the product model you are looking for. For third-party purchases, keep your proof of purchase and confirm the seller's return and warranty procedures before ordering.

Contact the original seller before using the product. For an eligible official-store order, Viltrox Support can review return or exchange options under the current Refund Policy. Keep the product, packaging, accessories, and protective materials in original condition. Third-party purchases should be handled through the original seller or platform.

Return eligibility depends on the reason for return, product condition, purchase channel, and current policy. Under the current no-reason return terms, unopened packaging requirements apply, and opened or used products may not qualify for a full refund. Contact the original seller or Viltrox Support before sending anything back.

Demo availability depends on local retailers, exhibitions, and events. Check camera retailers in your area or contact Viltrox Support with your country or city and the product model. We recommend confirming demo stock with the retailer before visiting.

For bulk or business purchases, provide your company name, country, delivery city, required models, quantities, and contact details. If the request is for resale or distribution rather than end use, include your sales channels and expected purchase volume so the appropriate business team can review it.

Pre-order availability depends on the specific launch and region. If the product page does not offer a pre-order or reservation option, do not assume support can manually reserve inventory. Monitor the official page for stock updates and subscribe to restock notifications when available.

Send a concise proposal that includes your name, country or region, portfolio or social links, audience profile, the Viltrox product you are interested in, and the content you plan to create. Collaboration requests are reviewed individually, and submission does not guarantee product support or sponsorship.

Please provide your company name and registration details, website, country or territory, existing sales channels, relevant brands or product categories, the Viltrox product lines you are interested in, expected order volume, and a business contact. The appropriate sales team can then review the opportunity.

Viltrox offers affiliate and cooperation opportunities for eligible partners. Review the current official cooperation information and submit the requested profile and channel details. Approval, campaign requirements, and commission terms can vary by program.

Do not use firmware from another product page as a substitute. Confirm the exact product model and mount, refresh the official Download Center page, and try the correct product entry again. If the link is still missing or incorrect, contact Viltrox Support with the product model, page URL, version shown, and a screenshot.

First confirm that the computer has a stable internet connection. Retry using another network if available, and make sure a VPN, proxy, firewall, or security application is not blocking the updater. Restart the updater and reconnect the product. If an official manual firmware package is available for your exact model, follow that model-specific method instead.

Use the storage device and file-system format specified in the update guide for your exact monitor model. If the guide requires FAT32, format the supported USB drive or SD card accordingly and place the extracted update file in the required location. Do not assume that the same storage format or capacity works for every monitor.

Confirm that the firmware is for the exact monitor model, unzip the download first, place only the required update file in the root of the recommended FAT32 storage device, do not rename the file, and remove unrelated firmware files. If it still fails, contact Viltrox Support and provide a photo of the storage contents, the current system-information screen, and the error message.

No. Firmware is model-specific and may also depend on the hardware revision or mount. Never install a file that is not explicitly listed for your exact product. Using firmware from another model can cause startup, recognition, communication, or update failures.

Use only the file explicitly listed for the exact adapter model and hardware revision. Firmware numbering is not shared across different adapter families. For example, a version number associated with another adapter is not evidence that your model should use the same release. If the download page appears inconsistent, send a screenshot and the adapter label to support before updating.

Turn the camera off and do not force the adapter. Hold the camera's lens-release button and make only a gentle, normal removal attempt. If the adapter does not release, stop to avoid damaging the mount. Contact Viltrox Support, the original seller, or a qualified service center with clear photos or video before attempting any disassembly.

Shared-power issues can depend on total battery output, port ratings, USB-C PD negotiation, cable capability, and how the load is distributed. Test the monitor and camera on separate outputs or separate power sources and use known-good cables. If the problem is repeatable, contact Viltrox Support with the battery model, port specifications, connection layout, monitor firmware, camera model, and a short video.

Disconnect all power sources, including battery, DC input, and USB-C, wait briefly, then reconnect only one power source and test again. If the screen, fan, or power LED still behaves abnormally, stop repeated power cycling and contact Viltrox Support and provide the exact model, firmware version, serial number, power source, and a video showing the shutdown behavior.

Available de-squeeze ratios depend on the monitor model and firmware version. Check the current monitor manual and on-screen menu for the supported options. If the ratio you need is not listed, contact Viltrox Support with the exact monitor model and firmware version before relying on that workflow.

No. Video monitoring and camera-control communication are separate functions. A camera may output video normally even when USB, Wi-Fi, or cable-based camera control is not supported. Check the exact monitor model, camera model, camera firmware, connection type, and required control cable for the function you need.

Some processing delay can occur in an external monitoring chain. Camera HDMI output mode, interlaced output, frame-rate conversion, monitor processing features, and cable quality can increase latency. Where available, test a progressive output such as 1080p, disable unnecessary processing features, and compare with another cable or source.

Image rotation and full portrait-menu layout are separate functions and can differ by model or firmware. Check the current firmware and rotation settings first. If the image rotates but the UI remains landscape, contact Viltrox Support and provide the exact model and firmware version so the available orientation behavior can be confirmed.

For full electronic operation, choose the flash version designed for your camera system. Brand-specific hot-shoe communication affects TTL, HSS, camera-menu control, and other functions. A different version may physically mount but should not be considered fully compatible. If you ordered the wrong version, contact the original seller before use.

The Z1 Pro line is offered in dedicated Canon, Nikon, Sony, and Fujifilm versions. Panasonic is not currently a dedicated Z1 Pro TTL system version, so full TTL, HSS, and camera-menu compatibility should not be expected. Check the latest compatibility information before purchase.

Do not bend, reshape, or repair the hot-shoe foot with tools. The mount contains mechanical and electrical contacts that can be damaged further. Stop using the flash and contact the original seller or Viltrox Support with clear photos from several angles and proof of purchase for service guidance.

Check the current product manual, dimension diagram, and official accessory information first. If the mechanical dimensions you need are not published, contact Viltrox Support with the exact monitor model and the mounting points or measurements required. Do not assume that different DC-X generations share identical hole positions.

First confirm that the extension tube mount matches both the camera and lens. Extension tubes increase magnification and reduce minimum focusing distance, but they remove infinity focus and can affect autofocus, stabilization, or exposure behavior depending on the combination. If your exact setup is not listed, contact Viltrox Support before purchase.

Power off the camera and remove the lens. Confirm the correct mount, make sure the electronic contacts are clean and dry, and check the recommended camera and lens firmware. If possible, test another lens on the camera and the Viltrox lens on another compatible body. If the problem is repeatable, stop repeated testing and contact Viltrox Support with a short video, firmware versions, and the lens serial number.

The aperture value shown by a camera can depend on how the body reports or rounds aperture steps and on electronic communication with the lens. Confirm the exact lens model, camera model, and firmware versions. If the maximum aperture is consistently displayed incorrectly or exposure behavior is affected, contact Viltrox Support with photos or video for verification.

If repeated clicking is accompanied by failed autofocus, aperture control, or camera errors, stop using the lens. Power off the camera, reinstall the lens once, and record a short video of the behavior. Contact the original seller or Viltrox Support with the camera model, lens model, serial number, firmware versions, and proof of purchase.

Teleconverter compatibility depends on more than the camera mount. The lens must provide the required physical clearance, optical compatibility, and electronic communication. Check the latest compatibility information for the exact lens and teleconverter before use. Do not assume that every lens on the same mount is compatible.

If the mount is compatible, some full-frame mirrorless cameras can use an APS-C lens in crop mode. The recorded image area, resolution, and available functions may change. Confirm that your camera supports the required crop mode and check the exact lens/body compatibility before purchase.

Minor differences in markings, labels, packaging, or cosmetic details can occur between mounts, regions, or production revisions. If you need to confirm the exact version or authenticity, contact Viltrox Support with clear photos of the product, model label, serial number, and packaging.
