Hope this don't sound like a stupid question but, How can I test my 3 lens? If I take a picture with all 3 of the same thing and the settings can I compare the 3 pictures. If so what is the best thing to take a picture of? Should I use a flash or go outside in the sun? I just want to see which is my best lens? I know I don't have any high end lens but i would like to know what would give me the best picture.
