I've had my EOS Digital Rebel for over a year now. I mainly use the camera for landscaping pictures at night/day and some interior room pictures of houses that I sell. Here is what I have done.... I love taking night shots and I would really like to upgrade my lens or just get a new camera. What would help me the most to get better pictures for landscaping? I am using the stock lens 18-55mm f3.5-5.6 a better lens or a newer camera?
