Default A200 + Sigma 24mm @ 1600 ISO

Boredom encourages photography. When I have nothing to do, I grab my camera (whichever is handier) and experiment. This time it happened to be my A200 with the Sigma 24mm (already mounted on it) and I decided to try some high ISO shots in normal daylight conditions. The idea was not to find out how noisy (or not) the images would be but how much detail would be retained. Why? Well, the higher the ISO, the more room I have to play with shutter speed and aperture. The results were quite good (IMO).

You always seem to get great results from that Sigma lens. I'll keep that in mind if I ever need a 24mm prime. Right now, my shortest prime is a Minolta 28mm f/2. I usually use a Tamron SP 20-40mm f/2.7-3.5 if I need anything much wider that that.

Thanks, Jim. It is one of my fav. lenses (as you've probably already guessed). It's small, fast, sharp and has macro capability. The only negative is that it's a bit noisy when it tries to focus from far to near and vice-versa. But, I can certainly live with that.

Besides the lens factor, I am encouraged by the quality of the images taken at ISO 1600. If you look at the cloud shot, it was taken with shutter at 1/4000 and sperture f/16. That would be a great S/A combination to photograph wild life!
