Resolving power of a sensor.

Recently I had the opportunity to very closely examine images from my old
RZ67 (haven't used it for 2 years) and some 1D MkIII Canon images. The part
which surprised me most was in the resolving power of the sensor - or the
lack of it, compared to current version film.

This anti-alias filter deliberately blurs the image before it reaches the
sensor. Doing that destroys detail that a nice camera like the RZ preserves.
To a lesser extent Fujifilm (but digital?) s5 Pro also uses an anti-alias
filter but not as strong as the Canon so it's images "appear" to resolve as
much detail from a smaller sensor.

I shot a roll of Portra VC at a recent shoot and scanned the film on my new
"wet Bed" scanner. As close to a perfect scan as I've seen lately. The
results really are chalk and cheese under close examination. Sure the
digital image "looks" stunning, more so than the film shot but at pixel
depth resolution, the RZ images shows considerably more detail that wouldn't
ordinarily be seen unless you made a very large print.

How this will fit in with a market geared to quantity of image rather than
quality of a few, I'm not sure but it certainly will fit in nicely with my
very big landscapes.
