El material no es taan bueno pero cumple su función y está a un excelente precio.

I am very happy with this product. I was looking for a way to reuse some of my lenses from my old film Pentax on my Sony A6000. I figured that the $15 or so I would spend on this would be worth it, even if the image quality didn't turn out super great. I wasn't sure if the adapter would have any negative effects on focus distance or things like that. So far I haven't seen any noticeable differences and the images are better than I could have imagined! Absolutely stunning shots on some of these older lenses. And it's so fun to have the live view, live exposure, and face recognition all still working. The build quality is sturdy. I was worried about it being flimsy like some other cheap adapters, but it's solid. I do have some pretty tight contact on the lens side like others have mentioned, but nothing that would damage my lens or anything. My only real gripe (but not enough to drop it a star) is the little metal tab you can see in the product picture that released the lens when you want to take it off. I really have to fiddle with it to click it into the release position, and as I do so I'm almost afraid I'll break it. But over the week or so that I have been using it and actively taking lenses on and off it's gotten easier and no closer to breaking. I'll update this review if it does later.

It's cheap and it works. I bought the adapter to put an old Takumar zoom lens on my A3000. For an old pawn shop find, the lens isn't horrible, and this adapter works fine to let me use it with my mirrorless. I plan on finding more cheap Pentax glass for this adapter and for my K-1000 film camera. Pros: - Cheap - Adapts your K-mount lenses to your E-mount camera - Permits infinity focus - Simple - put it on the lens then put the lens/adapter combination on the body - Build quality is comparable to other Fotasy adapters (I also own the Canon FD one) - Build quality is pretty good, the lens mounts solidly to the adapter and the adapter to the camera Cons: - Works best with old K-mount lenses that have aperture rings and manual focus - Non-electronic - this is only a con if you require autofocus or electronic aperture control There are a couple of things to do to make this camera and any K-mount lens work together: enable "Release w/o Lens" in the camera's options, and get used to setting aperture manually. You can use Auto ISO by setting the camera in Shutter Priority (S) mode on the dial, then setting the aperture on the lens barrel and adjusting the shutter as you like.

Compré este adaptador porque tenía la idea de usar lentes con montura K en mi sony Nex, ya teniendo el adaptador en cuestión, sobra decir que es de buena calidad, es algo pesado (es de metal) pero sin duda cumple con creces lo que promete, por cierto, el precio y calidad son insuperables.
