FotasyLeica M Mount Lens to L Adapter, Copper, LM Lens Adapter to L Mount, Compatible with Panasonic S1 S1H S1R S4 S5 Leica SL SL2 TL2 TL Leica T Sigma fp fp L Mirrorless Camera

This adapter works perfectly. It fit great, and attached to my Panasonic S1 with no problem. I used a Voigtlander 21mm f1.4, and on the lens side it was smooth and locked solid. No need to pay for the more expensive Leica adapter.

This adaptor works fine. It is well made but is very, very tight. I ordered a second one and when it arrived it was exactly the same. Conclusion - they are made to a very-tight tolerance so it is tight to install and remove. If that doesn't worry you, you will love it.

Using it to adapt a Voigtlander NOKTON Classic 40mm F/1.4 VM to a Panasonic L mount camera. It was just right. Couldn't ask for a better fit. The build is solid

Works well. Good buy.

I ordered it this morning, received in the afternoon. Fits nicely on my Canon Dream Lens with M mount and SL2s, not feeling too tight in my case, and no play at all (the novoflex I was using was too loose on the M mount), so far happy with it.

The adapter has a latch instead of a button but the price is good and it locks on tight.

When viewed from the side that faces the sensor, the flanges of this adapter are not painted black. Therefore there are some internal angles where light reflected from the sensor can reflect back onto the sensor. The Leica adapter (at ten times the price) is painted black on all surfaces. This does make a difference. On some cheaper adapters I have painted the interior black myself. But on this one I think I may end up buying the Leica adapter.

I was obviously happy to see there was a much cheaper alternative to the expensive adapter sold by Leica, but skeptical none-the-less. None of my lenses are six bit coded, so I have no need for the electronic contacts missing on this adapter, but I was worried about how the camera would react to this. From my experience, lenses worked just fine with the adapter. My main issue with this product was the lack of polish, some of which is purely aesthetic. There are a few spots around the edge where the metal is kind of ragged and feels unpleasant to the skin. Also, when I first put on the adapter it wouldn't catch and lock in place. Upon inspection, I realized there is a little hole milled out where a pin on the camera locks into. This hole is filled with red paint on the adapter, and the paint had filled so much of the hole, that the pin couldn't lock into place, so I scraped some of the paint out, and now the adapter works fine. If you are willing to overlook a few issues, and scrape that paint out, this is definitely a decent alternative to the expensive adapter from Leica. I'm quite happy using the T with my M lenses.
