Hi!
Jarek, this is wonderful test... Indeed Polish can be read with some
thinking and practice having Russian as a base... Well, at least to some
extent and bringing another Russian speaker (wife) along ;-).
1) all three primes are better performers than all three zooms.
2) at some focal length/aperture combinations, the differences between
the better zooms and the primes becomes small.
3) the tamron 28-75 and the pentax 20-35 are clearly better performers
than the DA18-55.
4) the differences at equal focal lengths between the 28-75 and the
20-35 are pretty small, and which is better depends on specific focal
length and aperture setting.
5) the 18-55 is not a bad performer; it just isn't quite as good as the
others.
Godfrey, at al, I have a question. My Sigma 18/3.5 is a fine piece of
glass... I've nothing about it except that it is manual focus... I like
to shoot things that involve close-far motif and the close piece is that
close that DOF scale based approach may not work...
What are my options... I am leaning towards FAJ 18-35 lens since both my
bodies (MZ-6 and *istD) have aperture control from the body... I decided
not to buy any reduced image circle optics, so this lens seems the only
choice if I am to go wider than 20 mm...
What do you say? Or must I go to third parties - Tokina, Tamron? They
have 17-35/2.8-4 group of zooms...
Thanks!
Boris
