I am a brand new owner of a d5000. I got it with the 18-55 nikkor and the 55-200 nikkor. I would like a lens to use for macro photography -- plants, shots of my reef aquarium, etc. 1:1 -- any advice? I am a newbie to dSLRs and Nikon. Thanks.
Welcome to Nikonians! What is your budget? If you want a 1:1 ratio lens to be able to use the camera's meter to set the exposure and the AF to function your choices are somewhat limited to the following: 1. Nikkor AF-S 60mm f/2.8G Micro 2. Nikkor AF-S VR 105mm f/2.8G Micro 3. Sigma 150mm f/2.8 EX DG Macro 4. Sigma 180mm f/3.5 EX DG Macro 5. Tamron 90mm f/2.8 Di Macro II All of these lenses are very sharp. The longer the focal length the more working distance (lens to subject) you will have. You will also want a quality tripod as there is very little room for error when focusing at 1:1 as the Depth of Field (DOF) is very very narrow. Be ready to use Manual Focus as well. Good Luck and Enjoy your Nikons!
