Adapter fits perfectly on my Sony a6000. Looks and feels very well made. For a low investMent it allows you to use your legacy Minolta Rokkor lens. You can expand your lens collection inexplicably with those legacy SLR lens. I currently have a Minolta Rokkor MC 50mm and a Vivitar 85-205mm zoom; both fit perfectly to the adapter and the adapter to camera base. You just have go back to your roots and manually adjust all settings. Focusing was easy. I did notice a lag in the viewfinder when adjusting the f stop using the Vivitar zoom, but not difficult to get true view before shooting pics. Rokkor 50mm works great.Just took a couple early morning pics with my Minolta 50mm. 1/320, ISO 3200, and f 1.7 (manual settings) Pic as shot and I didn’t do any editing/corrections. Enjoy!

Works flawlessly - using a Minolta MD to Sony Nex adapter.Fit is perfect, and the adapter comes off the body with ease - same with removing lens from adapter.This adapter has allowed me to use all of my old MD/MC lenses instead of letting them sit around for the occasion when I haul out my X-700.

Je l'utilise pour monter un Minolta MD 50 f/2 sur un Sony A7.Pas de problème.La mise au point manuelle n'est probablement pas assez précise avec le focus peaking, il faut que j'essaie la loupe.

K&F Concept マウントアダプター Minolta MD MCレンズ- Sony NEX Eカメラ装着用レンズアダプターリング マウント変換アダプター問題ありません。コスパ良し！

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

Works exactly like it should. I bought this adapter instead of the second generation that K&F offers because of all the negative reviews that the newer one has. This one works and looks great, attaches to the body of the camera really well but the lens side it pretty tight, not too tight just tighter than I am used to. LOVE being able to use all my Minolta lenses on my A7R, (35mm f2.8, 50mm f1.2, 85mm f1.7 and a few others). Brings new life to old vintage lenses that would otherwise be sitting on the shelf with occasional use with my film cameras. If you're on the hunt for a MD-E-mount adapter for your old Minolta lenses, BUY THIS ONE. I got exactly what I needed and all my lenses focus to infinity as well. (actually slightly past infinity but thats better than not being able to at all).

I give this 3.5 stars. I use this with a number of Minolta MD's - 28 f/2.8, 28-85 f/3.5-4.5, 135 f/2.8 and 200 f/4. I've not noticed any light gap problem that I read about just now prior to writing this review. The only thing I find annoying is the infinity focus issue. I like to not spend much on these items but as I use more and more MD's it would be nice to have access to that very simple feature of manual focusing. Thus if not on a budget seek out an adapter that gives you infinity focus. Though I do have 4 lenses I use only one adapter, leave adapter on camera and just switch out lenses. Pic w/ MD 28 2.8.

もう使うことも無いと思っていたミノルタのMDレンズがデジタルカメラで復活しました。ガタつきも無く、取り外しも滑らかです。
