I just sold off all of my medium format and 35mm manual film equipment. This is the equipment that I learned photography on; shooting, developing and printing b& w as a hobby mostly landscapes still life and an occasional portrait of a person doing there work in their work environment using simple on camera flash. I no longer have access to a dark room and photography is still a hobby with no intention of doing more than a hobby. I feel as though a DSLR is prohibitively expensive! So I am considering a Canon Powershot A640 that I have priced for $250 to $320. My girlfriend owns a Canon Powershot A540. I like this camera in so far as the 6-mega-pixel resolution is fair to my eye. What I need help with is this. Is the 10-mega-pixel worth the trade off of advanced features in that of the 8-mega-pixel S5-IS that is slated to come out in July with a price tag of about $500. Could anyone please show me some real differences between a 10mgpix and an 8mgpix image as well as some short videos shot with both. Please help, thanks in advance.
