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.
