I have been really busy with school and sure do want to start shooting again! I have a Canon 15-85mm attached to my 50D most of the time, but I find it too slow in low light. I do have a Sigma 30mm f/1.4 prime. Do you guys think I should sell the 15-85 for the new Sigma 17-50? I don't really mind losing out on the longer zoom range. I typically shoot portraits, random stuff, and sometimes cars. What do you guys think?

You could just add a flash unit if you don't have one already.

since u alrdy know what you are after, then go for the 17-50. you will definitely benefit from the constant f2.8.

just take note that you are not only losing the long end, u are also losing 2mm on the short end, which is quite alot. u also lose the full time manual focusing of the 15-85.

Try shooting the sigma at 2.8 and see if that is enough. For me, 2.8 isn't enough for my indoor use. I need a flash or use my sigma 30mm wide open.

aren't most portraits shot in the 50-85mm range?
