I just finished my beginner photography class, so i want to buy a good quality slr digital camera. I cant decide between canon eos 30d, rebel and nikon d80. I frequently take photos of landscapes and portrait, so i need a good quality lens also. I heard that lenses that comes with the body of the camera is not really good, compared to buying a separate lens. I am planning to spend around 900-1200 $ . So whats the best choice for me ?
