Hi guys, Am looking to get into digital wildlife photography. but, I dont no really anything about camera's except megapixels make the picture more clearer. Can you help me out guys? I want to get some thing that would be good yet cheap. what would be the best digital camera for me to buy? my budget is $100. I don't mind buying second hand either. If you can recommend some cameras or tips or something that would help me out. Thanks in advance!
