I purchase these over time and kept them on the Canon lenses. They fit just right and mate to the Sony body perfectly. No surprises, no disappointments. Great to reuse the vintage lens collection and save a ton of money at the same time.

Breathes new life into existing Olympus lenses. Perfectly adequate build quality, especially for price. Easy to swap lenses in and out. It's a mixed bag because the value of many OM primes is that they were so small and because of the necessary flange distance the actual height of the adaptor is nearly as much as the lens itself! Still, though, the resulting package is lighter and easier to use than a lot of native Sony primes, so it's very worthwhile to me. Totally recommend.

This is a great adapter that allows me to use a Canon FD 50/1.4 lens with my Sony a7s. Use the mechanism of your Canon FD lens to attach the lens to the adapter and make sure that the aperture/diaphragm control pin lines up appropriately with the mechanism for adjusting it on this adapter (it will feel like it has the correct "click" in when you do that and will easily mount).Once attached and placed on your camera, this adapter along with the Canon FD aperture open/closed feature allow you to focus wide open and then immediately close down to your desired f-stop using the "Lock Open" ring on the adapter. That is a fantastic option to have for a manual focus lens and really assists with precisely positioning the focus point and with focusing in low light if you want to shoot stopped down. This feature alone, which I believe is unique to FD mount lenses, is a good reason to give preference to using FD lenses with the Sony a7 series. (My 35-70 zoom, however, is right now a Minolta, but this feature makes me think about using Canons also excellent 35-70 FD zoom).My first copy of this did have a significant amount of "play/wiggle" and eventually came undone. I should have contacted the seller (HiShop) immediately. I ended up contacting them via the "question about return" policy option *after* the return period had expired. They graciously replaced my adapter with a new one that works great and has no wiggle. I am very pleased with the product.

1) All of my Zuiko lenses are sitting too far from the sensor - Infinity focus happens when their distance scales are at about 7 meters. This is not really an issue when manual focusing, but I can't rely on a lens barrel's Infinity stop. It's a good thing the Sony a6000 has Focus Peaking and Ficus Magnification - they are absolutely necessary for manual focusing at Infinity using these adapters.2) All of my Zuiko lenses can be focused more closely than on an OM body. This somewhat compensates the Infinity-focus problem. :-)3) All of my vintage zoom lenses lack the resolution that can be captured by the Sony a6000 24MP sensor. They are just soft, even in the center at f/8, even though they were mire than acceptable with film.4) Only five of my Zuiko primes are up to the task: 50mm f/1.8, 50mm f/3.5 Macro, 55mm f/1.2, 200mm f/4 and 300mm f/4.5. The rest are too soft, wide open, but ridiculously better at f8. The 50mm f/3.5 Macro and the 200mm f/4 are spectacular with the Sony a6000 (at 77mm and 308mm equivalents).5) The OM to E-mount adapter exacts about a 1/2-stop loss of speed from the vintage lenses, much as would any extension tube. It's not a problem, thanks to good high-ISO performance.6) Many lenses made for digital sensors are designed to deliver the light as perpendicularly as possible - to avoid the CA (chromatic aberration) "purple fringing" seen with lenses that were designed for film. I'm getting a lot of CA in the corners of the frame, but it's easily fixed in Photoshop. Note: There's no CA by shooting at f/8 instead of wide open.Lastly: I later bought a Fotodiox adapter and a Fotodiox Pro adapter for comparison and find them to be essentially identical in quality and function, so far, except the blades that engage the adapter to the camera body are about twice as thick with this K&F Concepts adapter and the Fotodiox Pro adapter, where the blades for this Fotodiox adapter are quite thin - which leads me to believe this K&F Concepts adapter (or the Fotodiox Pro adapter) would be the better choices when mounting a heavy lens (or perhaps any lens). Otherwise, the most significant difference is their weights. The aluminum and brass K&F Concepts adapter weighs 3.5 oz. The aluminum Fotodiox adapter weighs 3.2 oz. and the Fotodiox Pro weighs 3.1 oz. See photos...All three adapters have a length of 33mm, from the body mount to the lens mount, and again, they all focus well short of Ininfity.Again, the blades that engage the adapter to the Sony camera body are the same thickness for the Fotodiox Pro and the K&F Concepts, but are much thinner (for some reason) with the Fotodiox adapter. Oddly, they all feel the same when attaching lenses or when attaching to the camera body.If I had to do it all over again and money were no object, I would get the Fotodiox Pro, due to its being the lightest of the three at 3.1 oz. vs. 3.2 and 3.5 oz and having thick blades, rather than skinny blades. But the K&F Concepts comes out on top for having the best price, the thick blades similar to the Fotodiox Pro, but weighing 3.5 oz. instead of 3.1 oz. I would avoid the Fotodiox adapter due to its thin blades, where attached to the camera body - they do not inspire confidence. Again, the blades are thicker with the Fotodiox Pro and this K&F Concepts adapter.

Just got this K&F Concept adapter for my Sony FX30, and it's been awesome. Needed something to adapt my Helios 44-2, and this thing did the trick perfectly. No issues at all, it just worked.The build feels super sturdy. Doesn’t feel cheap or flimsy, which is great. I was kinda worried about attaching my Helios to the camera, but this adapter made it easy. It fits snugly and securely, so I'm not stressed about the lens wobbling or anything.Installing it was easy too. Just popped it on my camera and the lens, and voila, ready to go. It’s manual, but that's obvious since it's for old m42 glassSo, if you're looking for a good adapter to use old lenses on your Sony, this K&F one is a great pick. Works flawlessly, feels solid, and it’s not too pricey. Definitely a good buy!

El mejor adaptador que conozco para lentes a rosca M42 a Sony (montura M42 a montura E) sin holguras y de calidad de construcción y ajuste perfectos.

He usado el adaptador para una Sony Alpha 7 y objetivos Nikon manuales. Hay varios modelos de esta marca, pero elegí este por ser el más ligero y estar libre de reflejos, las demás características no eran para mi imprescindibles de modo que cogí este y funciona perfectamente, de hecho el infinito casi casi corresponde a la posición de la lente.
