I just bought the 8 MP Digital Rebel from Amazon, after spending the past two days with my mom's Digital Rebel - I just love this camera! Some questions I have are - what are some good lenses to get for a beginner? I've never been into photography and want to learn. I will get the 18-55mm lens that comes included in the camera kit, but I was also looking at the 75-300mm with Image Stabilizer lens (once I can save up for it). Are there any other essential lenses I should have? What about filters? I don't know anything about filters, but which ones will I eventually want to get and what do they do? Also, just out of curiousity, Is there any way to take nightvision/infrared pics with this camera?
