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."
