>>3089330I work at a photo lab and we use one of these with a nikon d810 with an 85mm on it
Instead of the carousel top get a stack loader and load them in all with the emulsion facing the proper way oriented properly and its very easy to do
You plug the camera into the machine and it'll cycle through and snap each one and then you just load another stack of slides in. It's very easy to do and at work I've scanned at least 2k slides in a couple of hours before
