Great for vintage lenses

I've used other adapters and there was always a little bit of play with vintage lenses. This locking ef is a game changer for me.

I can't speak to the electronic pass through and auto focus performance, because that's not what I'm using it for. I was looking for a way to securly mount my old lenses, and I found it in this adapter.

Leica SL typ 601 DIED

My leica SL is died , totally cannot turn on after using EF L PRO VIltrox adapter

Erich Champion
Wonderful adapter!

Focusing is great with a 28-300mm on a Leica SL2. The adapter is a solid fit too. I think I would prefer a standard bayonet lock to the twist mechanism, but it’s nothing but a mild preference on my part. The mechanism seems to work well enough.

Can still use all my EF-lenses

Did some quick tests and can use my older EF-lenses without any problem.
