I am looking at getting a new camera to replace my old Nikon D70S and was hoping to get some opinions on the Nikon D5100 as a replacement? I am just hoping to take the usual, full tank shots and close-up macros. Also I have two old lenses, a Nikkor 18-70mm 1:3.5-4.5g and a Nikon Micro Nikor 105mm 1:2.8D. Can I still use these lenses and what other lenses would help me take better macro shots? Thanks and yes I know I should take a class to learn how to take better photos and understand all of the technology.
