I am planning to buy my first digital camera. It will be primarily used for travel, sporting events and maybe some weddings. I have looked at the Sony V3 and W-5 and Canon S2 and G6. I am looking for the best possible color and sharpness and battery life for under $500. If at all possible, I would prefer a camera which can take disposable alkaline batteries as well as rechargables, but it seems that the higher end cameras don't take alkalines as back-ups. I am looking for a camera that produces prints at least equal to a good 35mm for prints up to 8"x10". Thanks for all help.
