Fotodiox Lens Mount Adapter with Aperture Control, Pentax K Lens to Sony NEX E-Mount Camera

there is a fancy german one you can get for about 200 quid but why would you bother? this seems fineNB to release your lenses PULL BACK the little nobby thing towards the camera body. Don't push it in as it seems to invite as this doesn't work so one tends to thing oh darn it my 1000 quid pentax lens is screwed.remain calm and pull don't push and all will be well (Not necessarily in the universe or even your life, but at least your lens will release)

Does what it says on the tin. My old Pentax glass now works on my Sony E-mount. I've 3 favourite lenses that I've put to the test on it - infinity focus is always exactly where the lens says its going to be.As another review has noted, the release button is not the most intuitive part and even though I'd read his advice, I still panicked the first time when I attached a lens and thought it was stuck there forever. Once you've got the feel for it, it's a breeze and hurriedly switching lenses is no problem. It is comforting to feel that the adapter isn't suddenly going to let go of my lens. The camera side attachment is equally sturdy. It has been on and off the camera frequently and is never any trouble.

Good service. I was advised by the manufacturer that the product was out of stock (after Amazon had said it had been despatched) and the expected delivery date with the option to cancel. It arrived well before that date. Fits my a6000 well and the lenses, very well made

I use this to enable me to use my pentax wide angle and zoom lenses on my sony NEX vg10. it doesnt enable the autofocus using these lenses but give me great flexibility.

After trying a different one some months ago and it not fitting properly, I was very pleased with this one. It is of good quality and fits both lenses very well. Looking forward to using my old Pentax f/1.7 lens - it was an excellent lens.

works as expected. Maybe just a bit loose fit on e-mount
