K&F ConceptLens Mount Adapter Compatible with Konica AR Lens to NEX E-Mount Camera Body, Compatible for Sony NEX-3 NEX-3C NEX-5 NEX-5C NEX-5N NEX-5R NEX-6 NEX-7 NEX-VG10 etc

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.

Part 1 - Minolta MD to Sony NEX adapterTechnically, 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 adapterEdit: 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

This adapter was my latest in my quest to find an FD to E adapter that will truly focus to infinity. I have tried lots of different brands. All of them will focus to infinity with a lens 50mm or longer. Wide angle lenses are another story. I finally found one that worked with most lenses in the Fotasy PRO series. They are fine down to a 20mm lens. A 17mm lens is an issue for them. I bought several and some would just barely do it and some would just barely miss. I want one adapter per lens so I needed several. I wanted to KNOW it was right, so I tried this one.Let me start by saying the K&F adapter is the best built adapter I've tried. It fits the lens and camera perfectly. The aperture control is super smooth. When on a lens it feels as if it's an integral part of the lens itself. But can it hit infinity? The answer is yes, but with a slight problem. It goes past infinity by quite a bit. When the lens is properly focused on an object about 100ft away (which for the 17mm is pretty much infinity) the distance scale on the lens shows a touch over 10ft. It's not a lens issue as I have two of them they both show the same result. This could make using hyperfocal techniques difficult. But, it can focus to infinity so it's the one that is mounted on a 17mm at the moment.In conclusion, if you don't use the distance scale on your lens for anything this is the adapter to buy. It's decently priced, very well made, and will hit infinity with any lens. If you set your focus by using hyperfocal distance, then get the Fotasy Pro for anything 20mm or more.

Works perfectly. Adapts my Nikon lenses well and aperture control is smooth. I do with it would give me all the stops rather than just a few, but oh well. Lens locks in tight and seems very sturdy.

Worked great a d serves my purpose

Found my dad’s old gear one day and found that this adapter was worth a shot for the price. He doesn’t shoot with a camera anymore but I’ve been using a sony a7c and the 135mm FD lens mounted perfectly to that. I haven’t given the lens a true thorough cleaning, but my dad had it stored in quite a good case so there wasn’t 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 I’m unfamiliar with what lens coating the FD may have, so I have’t quite wiped anything around yet. I’ve 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 (I’m 110% sure that because I’m 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 I’m 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 you’re curious about. The only thing is, if you’re 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 don’t want any potential fungi spores for sure!

Just got this K&F Concept adapter for my Sony FX30, and it's been awesome. Needed something to adapt my Helios 44-2, and this thing did the trick perfectly. No issues at all, it just worked.The build feels super sturdy. Doesn’t feel cheap or flimsy, which is great. I was kinda worried about attaching my Helios to the camera, but this adapter made it easy. It fits snugly and securely, so I'm not stressed about the lens wobbling or anything.Installing it was easy too. Just popped it on my camera and the lens, and voila, ready to go. It’s manual, but that's obvious since it's for old m42 glassSo, if you're looking for a good adapter to use old lenses on your Sony, this K&F one is a great pick. Works flawlessly, feels solid, and it’s not too pricey. Definitely a good buy!

Great adapter!!

He usado el adaptador para una Sony Alpha 7 y objetivos Nikon manuales. Hay varios modelos de esta marca, pero elegí este por ser el más ligero y estar libre de reflejos, las demás características no eran para mi imprescindibles de modo que cogí este y funciona perfectamente, de hecho el infinito casi casi corresponde a la posición de la lente.

Encaja perfectamente tanto en mi cuerpo de cámara Sony A7 II, como en el objetivo yashica para el que quería este adaptador, además es metálico, no de plástico por lo que le da un aspecto de más calidad.

Perfect for vintage manual m42 lenses on my Sony a5100, build quality is all metal so it is durable and can hold the absolute tanks that are old Russian lenses. Especially when the lens weighs 3x the weight of the body :')
