I feel obligated to preface this by saying that I don't know your knowledge level, shooting style or environment. I'm sorry if I sound like I'm insulting your intelligence.
Originally posted by Noggin I am using the kit lens and like the zoom range but at ISO 1600 its kinda noisy.
Since someone else highlighted this, I'll jump on this line as well with what I notice. The 18-55 DA-L goes from f/3.5 at the wide end to f/5.6 at the long end. There's 1 1/3 stops there. Also, the automatic settings are reluctant to let me go slower than 1/100s at 55mm and 1/40s at 18mm. Using my K-r, 18-55 DA-L and bedroom wall ISO swings from 4000 to 800 by going from 55mm to 18mm. The ability for that lens to take acceptable pictures in low light, without a tripod, changes significantly depending on where you are in the zoom range.
I find the suggested shutter speeds to be more conservative than my liking. Though most of the time, I shoot static objects. They don't mind if I count to 10, take a few deep breaths, clear my mind, relax my body and go through the whole taking long exposures ritual.
That being said, what focal length or focal length range do you want to use in that situation and how many stops of improvement are you looking for? The suggestions so far seem all over the map and knowing these things will help.
