I have an Epson V600 flatbed scanner that does a good, but very slow, job copying 35mm negs. There's a film holder that holds 2 strips of 6 negs each, and the Epson Mac software allows automatically generating separate files for each of the images, with sequential numbering based on your specified starting point. I have a lot (hundreds) of old negs I'd like to digitize, but in many cases its only a few per roll. Seems tedious to bulk scan the entire roll 2 strips at a time, at about 5 minutes per strip including setup, only to delete the majority of the files. So, I'm looking into using my D90 with Nikon bellows and slide/neg holding units to quickly digitize. Found that it's not so easy to get exactly the right focal length lens to get the entire film image in the frame and have it well focused. A 43-86 used at about 80mm did a good job of framing, but the focus was mediocre compared to the V600. Grain was crisp and perhaps even a bit overly evident on the V600, while it was noticeably softened on the D90. Well, the 43-86 was one of Nikon's poorer lenses. I figured I should use a Micro lens. Turns out that the 55mm f/3.5 attached to Nikon's 1.4x telextender attached to the bellows would frame nicely enough that I can get a 2400x3600 full frame shot. But, to my dismay, no better than the 43-86. See below for a comparison of the 55mm with the V600. D90 on left, V600 on right. One possible cause: film holder unit has to be so far from the lens that the bellows on it won't connect to the front of the lens. Ambient light interfering with sharpness? I'll try putting a black paper tube there to see if it helps. Any suggestions from anyone?
