ISO 800 and 1600 are perfectly usable with the *ist DS so you can use
an f/2.8 lens very successfully.
I have no experience of that particular Sigma lens, but I'd much
prefer the Pentax FA28/2.8 all around. I'm just not happy with Sigma
quality control.

Ahh, you're right! *smacks forehead* I do a lot of street
photography at night because I don't have time during the day, so
it's basically street lights. Slowest I can hand-hold with an slr
is i'm guessing 1/30 (it's been awhile since i used a film slr). On
my old setup 1/15 and f/2.5 at iso400 was the worst i'd allow
myself to consider usable (http://www.flickr.com/photos/almost-

I'm leaning a bit towards the sigma, but i've read all sorts of
good things about the pentax 28mm. but then again that's not all
i'd use it for, so i guess i'm also looking for some sort of
comparison stopped down also vs. wide (wide wide) open. doesn't
have to be scientific, just if it holds up to looking "good". thanks!

Daniel,
You have to define low-light work to me. I customarily shoot in
'concert-like' settings; dark surroundings with spotlights on
performers...
I do not have either of the lenses you mention. I do use the FA*
24/2 simply because it has the largest aperture. This way I can
adjust the ISO on the *ist D to keep the shutter, and to a lesser
extent the aperture, where I want it.
Basically, for me at least since I have had different people say
low-light and had quite a difference in EV, I need to know what
shutter speed you will be shooting at different apertures to see
if the extra stop and a half would be worth it for you.

Hi, just want to get some opinions. I'm planning on getting an istds
and a 28mm prime, and I like to do low-light work. Which lens would
you pick, the sigma 28mm 1.8 or the FA pentax 28mm 2.8? I'm used to
shooting at a very crappy-looking iso400 on a canon g3 at f/2, but I
figure i'll be getting a usable iso400-1600 (at last! haha). Is the
extra stop (stop and half?) worth it? They seem to be the same price
around the internet. Thanks.
