Works very well, great price
My husband bought this and has this to say: "I recently bought a Sony a6000 mirrorless camera, and realized that my dad still had a few Olympus OM lenses from the 80s, so I purchased this to be able to use them.I've been using the adapter for about two weeks now, and it works exactly as advertised.The construction quality is pretty good: it doesn't feel like a cheap plastic toy, or like it's going to break easily. You have to exert a slightly high amount of force to put the lenses in, but I don't think it's a defect.The adapter doesn't offer any kind of digital control whatsoever: aperture control and focusing are entirely manual. While focusing can only be manual due to how the lenses are constructed, other (much more expensive) adapters seem to offer some kind of digital aperture control. In any case, the camera works perfectly with it when set to Aperture Priority mode, and if told to shoot even "without a lens".The only downside is that, while it allows focusing to infinity, pushing the lens focus to the infinity mark actually goes slightly beyond, and you have to correct the focus back a little. It's only mildly annoying, and you get used to it pretty quickly.One last thing to keep in mind is that OM lenses were made for full-frame cameras. My camera has an APS-C sensor, which is smaller than full-frame, so there is a crop factor with every lens I use. That's of course not the adapter's fault, but something to keep in mind.All in all, I can't complain at all given the price. It's doing exactly what it's supposed to do, and it's doing it well."

The good and the bad
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.

Solid build but a bit wobbly fit
It’s well made of metal with a nice milled lever to release the lens from the adapter. It comes in its own little box. The fit is a bit wobbly thoug, but I don’t think this has affected my photos so far . This Is the only reason I didn’t give 5 stars.
Good quality
It costs a bit more than other adapters but it's worth it because it's well made with no play whatsoever when mounted on the camera.

It should work just fine. I use it on the a6300 which is the exact same mount as the a7r.
