I am not sure if you are aware that this is 9000dpi, which is at least twice the linear resolution that is usually considered sufficient for color film. Naturally, details become soft at this scanning resolution at 100% view. Plus, the picture too bright, and not sharpened (no post-processing, as Bernard stated).
BTW, Ektar 100 is not the sharpest film around, anyway. But the lack of grain avoids the use of noise reduction in post-processing, which would always conflict with sharpness and easily produces a "digital" look.
Therefore, it is much easier to get a sharp, grain-free, good looking picture with Ektar than with a (theoretically higher resolving) Fuji film.
