K&F Concept PK K Mount Lens to Sony NEX E-Mount Lens Adapter, Compatible with Sony NEX-3 NEX-3C NEX-3N NEX-5 NEX-5C NEX-5N NEX-5R NEX-5T NEX-6 NEX...

Works perfectly to connect some of my great Nikon glass to my E Mount Freefly high speed camera. Fit is excellent and the release latch is smooth and easily releases the F mount lenses.

I used this to adapt some vintage yashica lens' to my sony a6000. It worked great! I attatched a picture I took with the lens of my cat.

Worked great a d serves my purpose

Found my dads old gear one day and found that this adapter was worth a shot for the price. He doesnt shoot with a camera anymore but Ive been using a sony a7c and the 135mm FD lens mounted perfectly to that. I havent given the lens a true thorough cleaning, but my dad had it stored in quite a good case so there wasnt too much to be concerned with aside from a finger print on the lens. I used my bulb blower to avoid loose particles mussing up my sony but Im unfamiliar with what lens coating the FD may have, so I havet quite wiped anything around yet. Ive since noted oil inside but not to a disastrous amount. That being said, the image quality was still sharp in the areas that were focused in on (Im 110% sure that because Im a novice and the controls on the vintage lens are different, the slight issues with focus were on me and not the equipment). With a good cleaning Im sure I could pack in this lens and this adapter with my own regular equipment, and use it as a solid portrait lens option. That adapter is definitely easy enough to install and take off for me to consider it. Do definitely recommend for the price, if you wound up with a lens that youre curious about. The only thing is, if youre using a vintage lens for the first time, definitely clean it to the best of your ability before mounting it on your beloved camera! I had no issue and my camera is fine of course but in hindsight I could have been even more careful considering the circumstance You dont want any potential fungi spores for sure!

Part 1 - Minolta MD to Sony NEX adapter Technically, it slightly overshoots infinity but the issue is easily corrected by dialing back the focus ring just a tad --- Not exact but clearly better than not-at-all. Although very light due to extensive aluminum usage, the build quality and fit-and-finish of the adapter is superb. Connections on the lens and camera mount sides are tight and precise --- absolutely, zero slop. The top of the lens release button is flattened making the lens removal process very easy and comfortable. Other notes: - There are no electrical connections so focus and zoom must be done manually on the lens itself - When mounting the lens, turn the adapter clockwise till you hear a "click" - Tested with a Minolta 85mm f/1.7 Rokkor-X MD lens mounted to a Sony a6000 camera ----------------------- Part 2 - Nikon Ai to Sony NEX adapter Edit: Based on my positive experience with the Minolta MD adapter, I also purchased the Nikon Ai adapter later. As with the Minolta MD adapter, the Nikon Ai version focuses beyond infinity a tiny bit. Fortunately, the same solution applies - dial back the focus ring and the horizon will become crystal clear. The build quality is impeccable and the finish is smooth and clean of burrs or machine marks. Connections on both sides are taut and precise with zero play. Additional notes for Nikon Ai adapter: - No electrical connections present so focus and zoom must be done manually on the lens. - Unlike the Minolta MD adapter, mounting the lens for Nikon adapter requires a counter-clockwise turn until you hear the "click" of the locking mechanism - Tested with a Nikon Micro Nikkor 55m f/2.8 Ai-S MF lens mounted to a Sony a6000 camera
