Quality differences between them ... very hard to call with respect
to the 6Mpixel DSLR bodies. I bet if I posted two photos at full
resolution taken with them you would be hard pressed to tell the
difference. They're both excellent.
What I find most pleasing about the 31mm is that it suffers
virtually zero
geometric distortion and is truly sharp to the edges on the 6MP
bodies, it
requires very little work in post processing even wide open. How
would the
Canon 28mm compare in these areas?
With the proviso that I've not done rigorous lens testing with
either, I would say the same for the EF28/1.8. Results out of the
camera with either of them have been very satisfactory, both of them
improve nicely with only light touches in post-processing. The Canon
28/1.8 is very similar in characteristics to the Canon 50/1.4 ...
slightly soft wide open, very sharp from one stop down, nice "glow"
and imaging qualities most everywhere. Focusing is fast and silent
with the 28 due to the USM ring motor.
These are very good lenses, not the low end harsh stuff. The Canon
100/2 is in the same category. The rendering *is* different from
Pentax lenses ... I liken it to the difference between Zeiss and
Leica lenses, where the Pentax is analogous to the Leica.
