I take a lot of action shots in low light conditions. This would include marching band competions at night (and indoors), indoor musical and theatrical productions and ice skating competions in indoor arenas. Up until now I've just always used a film camera (Pentax ZX-30) with a 80-300mm zoom lens (4.5- 5.6). I need to use a shutter speed of least at 1/90th, so I've been using 1600 speed print film. I have been very satisified with the results that I've been getting with film, but I would welcome the flexibilty of a digital camera. I would like to stay at a price point of $800 or less. That being said, if there was something at $1,000 that was clearly head and shoulder above everything else, I would certainly consider it. Not knowing much about digital SLRs, is it realistic to expect that a digital camera in the price range I've suggested can deliver images equivalent to film (realtive to graininess/noise) given the conditions I've described? Has anyone shot in conditions similar to what I've described with a particular digital SLR that has given them good results? Is there something in particular that sets one camera apart from antoher in its ability to produce images in these conditions (with the least amount of noise) that I should be looking for? (For my questions, assume all cameras are using an eqivalent lens; the lens should a constant and not be variable in this equation.) If anyone has any suggestions or comments, I would appreciate hearing them. Thank you.
