Hi, I just recently got interested in photography, and am purchasing a DSLR! Due to budget concerns I decided to get a used camera from craigslist. I have set up a meeting with the person selling the camera so that I can inspect the equipment, but I don't know what I should look out for! The camera is a Canon Rebel XTi, and the EF-S 18-55mm lens is included. The listing says the charger, battery, some memory cards, a UV lens protector are included. The picture has the strap on the camera, so I'm assuming that's included too. Other than that, I don't know what to look for ... cosmetic defects, sure. Are there any inconspicuous signs of damage or wear that I should know about? Thanks a lot!
