I've got a handful of old Minolta MC lenses that I wanted to use with my Sony NEX 3N. The adapter works perfectly with my lenses and camera and I couldn't be happier.

This is a well-engineered and tightly fitting, light-tight, correct infinity focus adaptor.

Unfortunately didn't fit my lens. But customer service was great,

very well made adapter with a real quality feel, my Rokkor 50 mm lens which has not seen daylight for a few years fitted perfectly

Works great with old manual focus Minolta lenses on a Sony A3000 camera. Fit of adapter to camera and fit of lens to adapter are both precise.

Excellent and tight fit. Gives me access to my older prime lens.

very very good - arrived on time and fit the camera like a glove!

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

Solid, simple, well-made, cheap; more than one could reasonably expect at the price. Cannot fault it.

Very good!! works in Sony Alpha a3500.
