Fotodiox Pro Lens Mount Adapter - Compatible with Leica M Lens to Sony Alpha E-Mount Mirrorless Cameras

I'm using this to mount a Leica 40mm f/2 Summicron-C to an NEX 7. It fits nice and tight, with no play at all. Leica lenses are known for being ridiculously well-engineered, and there's actually more play between the lens and the adapter than there is between the adapter and the camera body. Even pulling on it, the adapter fits the body so well that you'd swear it was actually part of the camera. The lens focuses correctly all the way out to infinity. I have not used the more expensive Novoflex adapters, but I honestly don't see how they could be any better than this product. From now on, all my NEX adapters will be Fotodiox Pros. The only complaint I have about this is that the lens release is a little bulky, and I have big hands, so sometimes I scrape my fingers on it. But I can't wholly blame Fotodiox for that, because the actual Leica lens release is in the same position, so I suspect that they had no choice but to put the release where they did.

Voigtlander VM adapter II is better in every way. It fits my lens better, build quality, adapter ring, lens lock and release knob are all better. It also looks more professional but depend on you taste. Buy a Voigtlander adapter if you have more money to spend and you should. This still a good cheaper alternative though.

I have to admit, this product works and the quality is nice! The reason for lowering to the 4 star from the 5 is that I bought another adaptor for a 1/6 of the price and it's just as effective/tight/compact. The main difference (where my $$$ went) was the button release, it's in the same place, but releases easier then the cheaper adaptor which is a little tougher to release. You photogheads can decide if that's a good thing or a bad thing. I lowered one star because I felt a little ripped off.

Adapter is excellent quality except the release pin broke after a few days. The pin design doesn't inspire confidence that it wouldn't break again so I'm going to look at other models.

Yes, you can get a plastic version of this for cheaper. But why spend a $1000+ on a camera only to skimp out on the adapter? The metal construction of the Fotodiox fits on very well to my Sony A7r. It's solid of construction and performs well in the field with quikc lens changes. The plastic versions, which I have tried with other lenses, often leaves a hard-to-scrape off plastic film on the grooves. In my humble opinion, definitely worth the price.

I have this on a nex-5n with a voigtlander 35mm 1.4 SC and zeiss 50mm 2.0 planar and there is no wobble at all. The adapter is also nice and thin so it doesnt add too much extra bulk. Infinity focus works just fine. I think there is a regular and pro model for this adapter. Make sure you know which one you're getting. I have other non "pro" adapters (nikon, canon) from fotodiox and those are not as well built and actually do wobble just a bit.

Unfortunately I did not have the good luck CH apparently enjoyed with his Fiodiox Pro Adapter. Fit to the camera seemed fine but when I mounted my otherwise tight Leica Summicron to the NEX 5N there was movement relative to the camera body (wobble) that, while not great, leads me to look to a different manufacturer for this part. I cannot advise you as to whether the problem is in the design itself or the result of unflattering tolerances in the adapter I received. Sorry.

The first one I bought had really bad "wiggle" so I returned it and the replacement was worse! I know it was the adaptor as it was the same with two different Leica lenses. Rather than return it altogether, as I do rather like the look and build of it, I added four little pieces of duct tape to the adapter (see pic). This little modification works very well and the adaptor is very ridged with no wiggle at all. Is there anything duct tape won't fix?

Having this adapter, it allows me to use the voigtlander manual lenses to the Sony A7, and it does it very correctly. Sits tightly to the camera, the lens sits tight to the adapter with a knob to release it smoothly. Good price, good quality.

Great product. All my leica m lenses (4) fit nice and snug and the same goes for the camera connection. I live in Ontario, Canada and I received my order in four days (including a weekend). No duties or brokerage fees were paid except for the hst at time of ordering. I cannot compare to the metabones or novoflex but cannot fathom their being worth the extra money. This is the adapter to buy to use m lenses on a sony e-mount camera.

Tolleranze meccaniche strette e accoppiamento con la baionetta molto solido.. sicuramente un adattatore di fascia medio alta, che peraltro presenta un profilo particolarmente minimalista (il diametro è ridotto sul lato della lente). Le lenti focheggiano a infinito senza alcun problema.

Gut - ein Adapter der fest sitzt und gut verarbeitet ist - würde ich wieder kaufen - ! ! !

Thought about getting the metabones adapter, but couldn't find at a price I was willing to pay. While still a bit expensive, it works very well and found no play in the lens at all.
