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."
Works very well, great price Works very well, great price Works very well, great price

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.

Allows me to use my old om zuiko lenses on my Sony alpha camera. But the lenses only work completely manually. I have not found any advantage. I got from the seller exactly what I asked for. Thank you.

If you hold the Depth of Field preview button (the button opposite the unlock button on the lens), that will manually stop down the aperture. Meaning, you are not just stuck at wide-open aperture. The only minor caveat is that you must hold this button down while you snap the photo. For some reason, the manufacturers of this adapter chose to include a stop that prevents the slider on the back of the lens from moving and thus stopping down the lens. This makes no sense to me why they'd go out of their way to prevent this very useful function.Even more confusing is why it's so easily removed. You just need some precision screwdrivers and half a brain. Remove the four screws on the silver plate, lift the plate off the adapter, and then you will find one small screw holding the stop in place. Unscrew the screw and remove the stop. Then just reassemble the back plate with the orientation shown in the image (the notched blade is closest to where the text "OM" is printed).You should be good to go! Now, if you hold the DoF preview button down while snapping your picture, the lens will stop down to whatever aperture you have the ring set to and you will be able to use the lens to its fullest potential. In auto mode, the camera will automatically adjust exposure once the aperture is stopped down.

Solid construction and tight fit. Wouldn't hesitate to order another from them!

I attached this to my Sony A7 III, and then fitted my collection of OM Zuiko lenses. The result is just amazing. Of course, the focusing and the setting the aperture is manual. However setting the Sony to display areas in focus has made the focusing so easy!I cannot see any vignetting, and I am blown away by the quality of the photos!

I thought this was a great quality adapter until I realized how bad of a light leak it has. Tried with multiple OM lenses so I know its the adapter. I don't know if I just got a bad one, but I can't recommend this. Really hoped they would work good for the money.

There is a bit of play on connection to camera similar to other adapters I have had but never seems to be an issuewhen taking photos.
