This post reminds me of when I first received my 1DS and, to my
horror, realised all the images coming from it were distinctly soft
at 100%, or in large print. Previously i had owned a D60, which
reinvigorated my passion in photography (although the plastic
build and AF left much to be desired), and I generally used the
Canon 50mm 1.4 and 28-135mm non-L zoom with it.
When I received the 1DS (I received it before many of the reviews
were published so was unaware of how harsh it was on poorer glass)
I put these lenses straight to use with it and started shooting
using a similar workflow to before...hence my disappointment.
Cheaper lenses cannot maintain quality across the film plane and at
various apertures, when using such a high resolving sensor.
As you can imagine I switched most of my lenses to better quality L
glass (although I love the 50mm 1.4), and found that the 1DS was
really quite incredibly sharp. I am still in awe of how
3-dimensional some images can look from that camera.
I have owned the 1D MkII for nearly a week now and must say that it
IS natively sharp. The 16-35mm L lens does not do it justice
(that lens never did on the 1DS!), and although at present I think
the images require a little more USM, they appear as good as those
from the 1DS (up to A3), and indeed better, in terms of noise and
dynamic range, IMO.
I think that there will be much comment of the 1D MkII having
issues with softness in these forums, when it is widely available,
because of it's cheaper price and wider usage with photographers
that tend not to use L glass.
Do you remember the sudden increase in signal-to-noise ratio on
these forums when the 10D was released?
