I am thinking of changing my Olympus C4000 zoom for a smaller model. I bought the Olympus thinking I would really get into photography and buy extra lenses etc. However I have never bothered and the size of the camera is a an issue (not that bad) when I go on holiday etc. However it is an excellent camera and I have no problem with the superb image quality. To replace it I was thinking of a 5MP compact camera, either the Pentax Optio 550 or a Canon S50 or maybe even an Olympus C50 as I really like Olympus camera's. At the moment I tend to be leaning towards the Pentax due to it having a large zoom lens (5x) and it is also slightly less bulky than the Canon (but the same size as the Olympus). I guess there are probably other models as I haven't researched it that deeply but these are three that come to mind. Anyone got any of these models or any advice please?
