Casio EX-Z55, Casio EX-Z50 or Pentax Optio S51
I currently own an Olympus D40. It takes great pictures and is fairly compact, but I want something that fits in the purse or briefcase. Am I correct that none of these will take pictures as good as the Olympus especially indoors?
Which one would you buy? Anything else tiny that I should consider? Is there a better one? I really wanted at least 5 megapixels, but would consider 4. The size and weight of this is a big factor. I want something that is always with me. Will I be able to give up the Olympus, or will I still need that for certain situations(good pictures for ebay auctions, etc.)?
