I saw the other post about getting advice for beginner buying a camera, and was thinking if I should reply to the thread or post a new one. The difference between the two posts is I am going a little more specific about what I would like to shoot. I am an absolute beginner with photography and cameras. I have just started to look for a digital SLR and would like to do photoshoot on models in the near future. I wonder if any camera is specifically good for shooting people? Or the few cameras mentioned in the other post (Canon Rebel XT, Nikon D40, Pentax K10D) are good for shooting everything in general? I also wonder what's the differnece between Canon Rebel XT and Canon Rebel XTi? About lenses, are Canon, Nikon and Pentax pretty much all give the same quality? I heard it from a salesperson in BestBuy when he compared a Canon and a Nikon SLR for beginners that Canon has more flexibility with changing lenses, while if you buy a Nikon, you will have to buy a new camera if you want to change the lens. Is that correct? Thanks in advance!
