[Yes] So for I'm happy with the RS2 copy stand. It's sturdy, and easy to use. The mechanism works smoothly to move the camera up and down. It's not as adjustable as the RS1, but using an Arca Swiss plate, once you get it aligned, you don't have to do it again so not a big deal. it's quite expensive for what it is, but that seems to be the case for anything today, and much of what you buy today isn't well made. This seems well made.
I'm using with D850 to copy various prints, slides and negatives. I'll likely use the ES-2 Nikon accessory to copy individual transparency frames, but I'm using this stand to make images of my full rolls of negs in PrintFile as contact sheets, with a 60mm Micro lens. Had hoped to use my Tamron 90, but didn't have the angle of view needed so had to buy the 60. Do test that the working distance of this stand will work with your chosen lens. As I said, it didn't with my 90mm lens for one of my intended uses.
I also got a Kaiser slimlite plano light table to light the transparencies, and that also works well.

[104.5 lb] Looking forward to digitizing LP album art and photos that do not fit on the scanner platen.

[104.5 lb] This is a simple and easy to use copy stand. It allows adjusting the camera height, as well as the distance from the column. The handle that adjusts the height lets you set the distance to the original quickly and accurately. I use the stand with a Sony 14 MP DSLR A290 camera. I recommend a fixed focal length lens for sharp copies, as zoom lenses do not have the same sharpness. The stand is made in Germany, and appears to be of excellent quality of manufacturing.

[Yes] I am using a Sony RX-10 with this copy stand and really like it. The crank to move it up and down is stiff enough to stay put but loose enough to easily move the camera. The only thing I had a little trouble with (and have since gotten better at it) was attaching the camera. The screw is fairly short and you have to line it up just right to attach.

[AC Input] DO NOT BUY THE KID REPRO, it is cheap and unstable, for kids like the title may suggest. this is the lowest model I would consider.

[104.5 lb] I am using for scanning . I attach Sony A7riii and shoot negatives so quickly. Perfect.
Its Sturdy and has a carry case , yet not too big for sesk area.

[Motorized] This is a sturdy, well built device that does the job. The initial set-up took less than 5 minutes. The one feature that I really like is the way the horizontal arm can be extended with the camera. This is really vital.

[Motorized] Very simple and reliable, holds a sony 99 and a zoom mens with no issues, simple to focus and review your image, definetely to advise

[Motorized] I'm using the Kaiser RS 2 with a Canon 5D III, RRS quick release plate, and Canon's 100mm IS macro lens to digitalize my 10,000 prints. I use two desk lamps, low heat bulbs, and plain white paper (as diffusers ) for lighting. This is working really well. The stand is solid with the arm fully extended, the carrier has no play, no creep. I'm able to get up to a 5 x 7 print in the frame with the 29 post, that's full frame- no crop factor. I've done over 6,000 prints so far, the work flow is amazingly quick, product is better than the original prints. No cons, easy five stars.

[Yes] I was very impressed with this piece of German engineering from the moment I opened the box. Mom wanted this stand to copy all of the old photos, and it is very capable and sturdy. The crank raises and lowers the camera very smoothly, and the camera is very secure on the mount. The stand comes in a wonderful hard case for storage. The setup is easy and intuitive, just like a fine Mercedes. I think the value for price is fantastic!
