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.
Personally, I have found manual lenses much better than AF for many reasons. Mostly because I can manually choose the focus and aperture control without setting my camera to that mode. Ultimately, this allows me full manual mode while my a6000 is in shutter priority or intelligent modes. This allows for beautiful pictures if you are not in a rush, and can take the time to perfectly focus. It takes some practice to figure out which aperture setting you need to provide the proper depth while focusing manually (you can go infinite or choose shallower depths). All in all, this is a very reasonable way to upgrade to a manual focus primary lens instead of $300+ for an e-mount lens (I paid $20 for the lens).
Note: Keep in mind if you are going to use something like this on an APS-C camera (pretty much all e-mounts except the a7), 50mm does not equate to the "human eye". In basic terms, if you use 50mm with APS-C the view will look zoomed in compared to you just looking with the naked eye (meaning you might have to back up to take the picture). If you are looking for the "human eye" perspective I would recommend a 28mm, 30mm, or 35mm. The 30mm is the closest (I believe its about 29mm APS-C is equal to 50mm on full frame).
Pros: cheap, metal, looks good, functions perfectly
Cons: no auto-focus (if that's your goal)
