On the LargeFormat website I've been seeing truly remarkable scans made with either a Nikon D800E or D850 and the Nikon 105mm macro lens, using a copy stand. They are doing three or four shot stitches. They seem to be matching drum scans. This is on my "2018 to do" list. I already have the camera and lens and a lightbox, looking for a copy stand on ebay.
