Hi Otis I got the older model 9900f form Canon for free. I like the scan results from negatives a lot despite the fact that scanning is very slow with Fare (scratch and dust removal)and the scanner has some ugly red and blue color tint when not (re)calibrated or just turned on.
Maybe that's fixed with the newer model.... Otherwise recommended. greetings Markus 8400F is about US$140 at BHPHOTO...... in NYC. Anyone using the more expensive 9950F? Otis Wright S
