I've had extremely good results with the Nikon Coolscan 4000. This is a middle line 35mm scanner. I think you could broaden your sample base if you ask the question here: DIGITAL IMAGING SOFTWARE & HARDWARE >> Printers, Scanners & Color Management
Roger It is still ISO, aperture and shutter speed, right?
I use a Coolscan V and am very happy with it. Limitations are will only do six negatives at a time and one slide at a time. The Coolscan 5000 will batch slides and will do a whole roll of film if that's your thing but the attachments are extra and pricey. The Coolscan 9000 does Medium format and is the top of the line. Those were the only scanners I researched when I wanted to get something to scan my negatives.
