my wife is wanting a compact digital camera. she has an old Canon Elph (non-digital) that she would like to replace with digital. she mostly uses her stuff for scrapbooking. the photos are mostly of our children. she will print an 8x10 (rarely an 11x14) for walls in our home a few times a year. in a small amount of research i'm considering these four models:
casio exilim ex-z57
canon powershot sd450
casio exilim ex-z750
canon powershot sd550
is the difference between 5.0 and 7.0 megapixels worth the cost? any help with the different models/preferences? are there other models/cameras that i should be considering? thanks.
