To flesh out my brief earlier response:
- My most recent 'scanning' setup for 35mm slide film is the Olympus E-M1 fitted with MMF-3 mount adapter and the Olympus ZD 35mm f/3.5 Macro lens, itself fitted with a Nikon ES-1 slide copying holder. Fit a slide in, point it at a nice even light source (flat panel light box for me), focus, set f/8, and shoot. It nets an 11 Mpixel image of the full 35mm frame once cropped to the image area. Resolution, dynamic range, and color are extremely good, and you have the raw files for detail tonal curve tweaking.
- For 6x6 and 35mm B&W negative strips, I use either a Nikon Super Coolscan 9000 or Coolscan V (35mm only). The Super Coolscan 9000 has a more diffuse light source and can load 12 exposures at a time (strips of six), the net result is it's a bit gentler on slightly damaged or dirty negs, and can scan more frames*unattended in batch mode (VueScan). The Coolscan V is a bit faster but has a harder light source, it can handle up to six exposures in a load. It's a bit easier to work with for 'non-standard 35mm formats' (like half frame, Robot square, etc) than the 9000.
I scan using VueScan with a raw workflow, that is, scan max resolution setting only the bias to capture the entire dynamic range, output to VueScan raw encapsulated DNG files. I annotate the DNG files with metadata using EXIFtool, then import them into Lightroom. Customized camera calibration files are applied which do the B&W reversal and tonal curve assignment. From there I export/import into 16bit TIFF files for finish rendering.
- For various other B&W negatives, I use a copy camera setup and the aforementioned lightbox...
