This clamp is AWESOME. It is so versatile. You can mount to poles, doors, edges of things, and you can use it to mount a GoPro camera to just about anywhere with the optional "Sametop Replacement Tripod Mount Adapterm https://www.amazon.com/Sametop-Replacement-Adapter-Compatible-Session/dp/B0126KXDN2/ref=sr_1_1?ie=UTF8&qid=1536940665&sr=8-1&keywords=Sametop+Replacement+Tripod+Mount+Adapter&dpID=51ak1cLKv6L&preST=_SY300_QL70_&dpSrc=srch

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.

MDコンポで育った世代としては驚きしかありません。この小ささ、この値段はお得です。

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

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.

This works better than Proactive or Proactive MD for my teenage son. I love the product for myself, too.

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。

I was looking for a hi-res webcam to use with OBS. I do Youtubes on electronics and need the ability to zoom into fine pitch circuit boards using an overhead boom. Image quality is great. The 5-50 mm zoom lens is decent, it does the job. A little fiddly, but for the price....I am trying to up the lens quality. I bought an adapter that allows me to use my lovely old Minolta MD manual (film) lenses with it. It needs a Cmount to Minolta MD adapter (~$20) plus about 6-8mm of Cmount extender tubes. If you do this, keep in mind that because of the smaller sensor, low mm (25-35mm) lenses are needed. I haven't yet found the perfect low mm zoom lens for it. Maybe a 28-70mm Minolta MD lens. There are many on Ebay. Have fun!Update. Using 35mm camera lenses works, but they are too close for this small sensor camera. Even my 28mm lens has a very small field of view unless you put the camera several feet away. So unless you want real close ups....
