Does exactly what it’s made for, no extra bells and whistles which is awesome in this case, and it doesn’t move around when moving the camera.

bought for Canon FD 70-210 F4 lens to use with a Panasonic G5IIx. Fits perfectly, no play. From the first test photos it seems to me that it can't focus properly to infinity. But that could also be due to the lens, but that's not important for my application. It's supposed to be for portrait photos, and with the lens it does what you'd expect

I’m very pleased with this inexpensive K&F Concept adapter. This fits both L-mount camera body (2023 Panasonic Lumix S5IIX) and L39 lens (1950s Leica Summicron 50mm) perfectly, allowing my modern camera to be paired with my late grandfather’s prized lens. Works beautifully and both sides secure well: I’m really happy with my purchase.

Seems very solid, autofocus works quickly and reliably on my XT30ii with Sigma 18-35. I can recommend it - especially for the price.

Betrayed by the age and weight of the bodies and lenses, I bought a lighter and more modern Sony body. The Canon 28-105 USM was a faithful companion, so I can keep it thanks to this adaptor ring.
