For color scans I generally use an Epson 850 but it's been actin funny so it's getting looked at. I pulled out a Canon 9000F II while it's in the shop and have been using it for color slide. Just scanned some 135 black & white from this weekend and I am really surprised at its quality. I am using Silverfast though... This was all shot on a Leica M4 BP with a 21mm Elmarit ASPH. I really love the FL on the rangefinder.

I previously posted this picture but went back to the RAW file and post processed it with Capture One for Fuji. It does a good job of bringing back the highlights.
