For my independent study project at school, I have decided to pursue photography to further develop my artistic interests. I plan to use a digital camera. As this will be my first experience with photography, I would like my equipment to be reasonably priced while still providing me with the greatest versatility so that I can explore as many aspects of photography as possible. For a budget, I think that $2000 would be my max for everything. For the body, I have been looking at the Canon Rebel XTi or Pentax K10D. These seem to get the best reviews for a camera under $750. I would like the camera to have as many different options as possible so I can explore different techniques. Any suggestions? I would like to start with no more than 3 lenses: a standard zoom, macro, and maybe a telephoto or wide angle. I want to have the greatest versatility with these 3 so any recommendations would be greatly appreciated. Can you use lenses on any camera, or can you only use a Canon lens on a Canon camera? I would like to be able to use the lenses on my next camera, so I would want a good quality lens, but not top of the line. If lens are proprietary, would I be better off starting with the Canon camera as they seem to make the higher quality cameras out of all the brands I know of. I also plan on getting an external flash. Do you suggest staying with whatever brand camera I decide on? Which filters would you suggest for a beginner? Is there anything else I should be looking for that will allow me to take a wider variety of pictures at a reasonable cost? What is a good site to buy used parts from? Thanks for your help.
