Hi I really think you need the most megapixels you can afford if you want larger prints, A3+ etc but for Pic to exe the smaller ones are fine. A really good site for reviews is at www.dpreview.com they seem to give in depth reports. I know someone with the Nikon and they are not that happy, yet someone with the Olympus E20 is delighted with the functions and quality of the images, but then the price is a lot more. Cheers Dahol
