Buy camera

I am new to camera world. And would like to buy a Digital camera (semi professional). Most of the time, I like do more outdoor shooting (both day and night on landscape or human). If possible I would like to do some product shooting in dark environment (such as mobile, mouse etc) as well.

Which camera would you suggest for me?
1. SONY A200k
2. Canon EDS 1000D
3. Olympus E520

Thks!

Erroll - all 3 are good and viable options. I would go for the Sony, if you wanted a budget system with outstanding quality, the Olympus if you wanted small size and weight, or the Canon if you want the most prolific system in the market.

I have a Canon EDS, the quality is good for outdoor and casual use, but you should have enough lighting if you like to shot in dark environment.

Wondering about the new, tiny Fuji camera and whether it takes good pics

All three are good options. If you have a larger budget, look at the D90.
