Hi, I'm new to this forum. For some time I'm doing available light shots at a Jazz session using my D70. I've bought the 50mm f1.4 AIS, which is just about fast enough for the available light (I use it at f1.4 almost always, with ISO setting at 1600), but a bit difficult to focus. I'm now looking for a similar fast wide angle to get a wider view. The Nikon 28mm 1.4 is out of the price range (unless one of you can sell it to me for around $500). I considered the Sigma series, offering f1.8 lenses from 20mm, 24mm to 28mm. I also saw a post in this forum, showing pictures taken with one of this Sigma lenses in Rome. I've read different reviews on these Sigma's, some claiming they may have focusing problems, as well as sharpness issues at the corners. Well, I'm not expecting wonders, just a lens that will work at the difficult lighting, and perhaps also perform well during regular daylight shots. Other alternatives would be the Nikon 35mm f1.4 AIS manual lens and the 35mm f2 AF lens, but I doubt the field of view will be big enough to capture the stage. The f2 might also be too slow. Your help and suggestions are much appreciated.
