Hi, I am venturing into photography and I'd like to someday sell prints of boats/yachts. Currently I have the Cannon G7 10 MP (2007) and I'm finally starting to understand and use all of its manual features. The summer season is approaching, however, and I'd like to be able to capture high quality images soon. What I mean by high quality is that I'd like to create 8 x 10 prints that I could sell for a reasonable profit. I know this doesn't come overnight but who knows? I might get lucky a few times as I learn. My question today is what somewhat older Cannon camera and lens will enable be to produce high quality images? Money is a factor at the moment and if I can get a used Cannon setup to help me get started that would be great. I am looking for the minimum equipment I would need. A strong zoom lens is of high importance I would think. Any tips, thoughts or recommendations would be very much appreciated. Thank you.
