Thank you.
Do you have an experience with Sigma 2.8/70-200, 4.0/100-300 or
2.8/24-70?
Sincerely yours,
Arthur Grokhovsky

i had the 15-30, which wasn't as well corrected in the corners and

all
Sigmas impart a strange grittiness and bokeh to out of focus areas of
the
image, whether film or digital. Pentax lenses don't do this, even the
cheap
ones.
