I have been looking at the scanner comparisson page http://www.largeformatphotography.info/scan-comparison/

And it got me thinking.... the scanning comparison page we were looking compares the scans at 2400ppi, the highest optical resolution of the v700 (which I am contemplating purchasing), however the drum scanners can go beyond 8000ppi!!! Even at the 2400ppi the drum scans are so much cleaner than the flatbed or the flextight which lies in between in my opinion. The comparisson image was a 4x5 film that * had a 10x enlargement if printed at 240ppi 40x50 print! I am wonder how much data does the 4x5 hold if the tango is so much cleaner. In other words at which ppi is the practical resolution of the film reached with the drum scan?....
