Great way to reuse old lenses!
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.

More non-Sony lenses, anyone?
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.

Great little quality device - NOTE incorrect lens release instructions
APPEARANCE/BUILD: The Adapter is well made, looks and feels solid - not chintzy. However you SHOULD know that its no more than a mechanical coupler b/w the two mounts with nary an electrical point. Which means there is NOTHING of the K mount lens you can control through the camera upon mounting. There is a well secured lens release tab mounted on the adapter which is about the ONLY other operational aspect you notice on the adapter. More on the lens release below. OPERATION on an E Mount: Owing to lack of electrical contacts, you eschew all automatic features of the Pentax lens with the adapter E mounted. In fact, the camera does not even recognize that there is a lens mounted because there is no transmission of electronic data to the camera simply because there are no contacts on the adapter. This means that with default settings, the camera's shutter won't fire. Which is why, to use your K mount lens, you need to set the 'Release w/o Lens' option in the Camera Menu - which upon doing will let the camera's shutter fire. The camera will then meter in Manual mode. As mentioned earlier, since there are no electrical points on the adapter, you lose the ability to aperture control the lens through the camera IF your lens does not sport the aperture control ring (someone correct me if I am wrong). My 18-55 Pentax kit lens cannot be aperture controlled because it does not have an aperture control ring. However my 28mm F/2.8 SMC prime's aperture can be mechanically controlled through the lens aperture control ring. Mounted on a Sony alpha 3000, if you press the bottom button next to the screen, the camera digitally zooms in to the focal point and you can manual focus to a greater degree of precision. You need a good fairly high resolution LCD to achieve this. It sounds complicated but is really easy once you get used to it. NOTE on LENS RELEASE: The lens release instructions in the small piece of included instructions are COMPLETELY wrong. As others have mentioned, put your fore-finger on the tab and pull it towards the camera - you will sense a spring controlled movement, then unlock the lens with a clockwise motion. Do NOT push the tab in or pull the tab out - you may break it. To its credit, the tab isn't flimsy and doesn't seem to break easily. However, that's not the point and that's not what you want to test. CONCLUSION: This is not one of those expensive brand name adapters like Novoflex, Voigtlander, Fotodiox etc - those are expensive for a reason and that is because they preserve the camera's AF ability on the cross mount platform. This is purely a mechanical device that couples one mount to another rendering all AF features redundant. If you are ok to treat your resulting setup as a fully manual focus setup, then this is a great purchase and would definitely recommend at this price. Am docking 1 star for the incorrect lens release instruction on the mechanical tab Thanks for reading.

Best piece of equipment that I have purchased
This find was absolutely FANTASTIC! The price was phenomenal. I have a Sony a6000 but really didn't want to spend a lot of money on different lenses and I found out by a review on youtube/Tony Northrup that you can use 36mm lenses. So I google what type of lens mount for the 2 cameras that we have and found out they were K-mount, I came over to Amazon and search K-mount to E-mount adapter and I couldn't believe my eyes for the price. I figured a) it wouldn't work or b) it would be cheaply made. Neither were the case. It works great and looks to be a quality made product.

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.
