Quality is good but the bolt which tightens the clip mount to keep it at some particular angle gets loosen now and then.

I love this mount. It is not compatible with the Nikon FTZ adapter unless you move it from the body to the adapter or buy another mount just for the adapter. I’ve hike a couple mountains and bustled through crowds without fail using this mount.

The bolt that held the telescope to the mount was too short to make a tight connection so I had to replace this before I could use it.

Mounted a bosch laser level using this tripod bolt mount. Worked flawlessly for the bosch dual plane level.

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

Good, solid mount.4 stars only as there is room for improvement.I need to use a pair of pliers to tighten the "T" bolt.If tightened by hand (and I have a very strong grip), it still allows the camera to tilt over.

This is a well built adapter. It's a very cool mechanism. However, one of the photos in the listing shows that the jaws open up to 2.28". If you were fastening to something like a table top, you could go up to a table top of about 2.25" thick. However, don't be confused. If fastening to a tube or pipe, comments from other users indicate that the biggest tube/pipe outside diameter that can be accommodated is about 1.5". The clamp wouldn't work on the 2" OD tubing I was using. My work around was to drill a cross hole in the pipe for a 1/4" x 3" long bolt that extended about an inch beyond the tube. The adapter easily clamped to the bolt. It would be nice if the add copy had pointed out that the maximum pipe/tube od that can be handled is 1.5". Nonetheless, I am very happy with this product.
