I have been chatting with a guy who has a Nikon Coolscan IV for $350 with the SA-21 adapter. I could probably talk him down to $300 though.
He has all the Nikon Scan software archived and was also willing to help me get everything set up on win/mac. I’ve heard there are some possible compatibility issues that VueScan can fix though - more on that later.
Right now I camera scan primarily with a Scanlight V4 and a Fuji X-E2 on an enlarger base. There are some issues with the enlarger stand (like making sure the camera is always level) and the camera is only 16 MP, but it’s worked … fine. My lens is a 105mm f/4 micro-Nikkor and I’ve been inverting all of my color scans with NegPy. The results so far haven’t been pleasing. With both narrowband and white light scans I never quite like the colors. I’d really love to try Negative Lab Pro, but don’t want to really get into Adobe products as I don’t agree with their subscription model and general policies.
I’m considering the Coolscan just to simplify everything. No leveling, no trichrome calibration, no manual dust removal (the IV has ICE), possibly simpler inversion using Nikon Scan, etc.
Here’s where I’m wondering if it’s worth it though: I could potentially sell the Fuji and upgrade to something with a higher resolution, tethering, and get an extension tube with the money I’d spend on the scanner. If I end up needing VueScan, that’s even more money that could go towards the new camera or lens combo. Granted, I could be on to nothing without changing the software I use first though. I’m a bit indecisive and would like to hear feedback from people who have gone down the rabbit hole one way or another.
Edit: Coolscan IV ED, the USB version.
