4490: 30lpm /mm
v700: 40lp/mm
the attached pics are different
4490 shot with 50mm lens at 3meters, the visible band is 2mm p line pair
width
v700 shot with 50mm lens at 2meters, visible band is 1mm line pair width
4490 scanned at 4800dpi

发帖数: 4965 | 5 given the small difference, I'd say v700 is definitely not worthy the 350$
difference, from a resolution perspective only .
considering 4990 also has lens (instead of the stupid pin-hole scanner on
4490), I suppose 4990 should bbe somewhere i in between ??
anybody could do a test? I can send negatives
