Great product. I use for negative and slide digitization. Highly recommended. Much easier than using a tripod mounted camera. I use it with a Sony A7R4 and the razor sharp just released Sigma 105mm dg dn macro lens.
Steady mount for Nikon D810 and 105 micro. Initial concern about the rough ride across a gap in the linear rack gear. "Mind the gap" issues resolved by reading the included info sheet. Info sheet includes instruction on gap closure.
Awesome copy stand at a respectable price. Holds camera near perfectly for digitizing film negatives. My only nit-pick is you can't adjust the very minute level of sag - I use a piece of folded paper as a shim to get it just right. Don't let that deter you from this stand. Very stable and simple to use.
It's not expensive, but it actually holds your camera absolutely parallel to the flat surface underneath. Most cheap stands allow for sag, i.e. when a lens starts tilting towards the leg under its weight. This one does it too (laws of physics!) but the base plate for the camera has two small screws you can you to adjust this. The end result is perfect alignment and 100% of the negative area is in focus.
To make sure you have everything perfectly, place a mirror in place of a film and look at your camera LCD. You should be able to see your lens iris 100% in the middle of the frame, right where the central focus point is.
Anyway, great deal and good product!
I'm using it with a Canon 7D and 100 mm f/2.8 macro. That combo is 3.4 lb and this stand can certainly handle it. Bogen-type attachment is very secure. Using bubbles to level things and my lens is perfectly parallel to the table. No moving or flexing. It's a bit tall for doing just this kind of work, but far better than inverting my hefty tripod and trying to slip a Kaiser Plano and film holder between the three legs. For having a sturdy, dedicated fixture and the right tool for the job, the price is reasonable.
