[QUOTE="WayneF, post: 491268, member: 12496"] I'd guess yes about others seeing it, since that's the design of the camera. That is sort of the price of an automatic camera, you do what it does. It is designed to try hard, but if you want more control, you need a camera model offering more control. I don't know enough to comment on their design, but after a quick glance, it seems very common on compacts, many Nikon and Canon models seem spec'd almost identically.
