I just don't know how to handle my new macro lens Nikon f2.8 60mm that I received in Xmas as a present. I am using Nikon D40 camera body. I have no problem with the original lens that comes with Nikon D40. I could use f5.6 to take a lot of close up (flowers , butterflies etc) and produce nice pictures. But with this Macro lens, maybe I just don't know how to maneuver . I tried to take close ups of small flowers and the pictures came out not sharp (not focused). Can any one give me some simple steps how to take close up pictures with this Macro lens? Do I have to change in the camera - focus mode , AF-area mode, shooting mode? If I have 3 flowers in the picture, should I focus on the middle one. How close should I put the camera? etc. I tried to search some articles on this subject and did not get much help that can explain why I have such difficulties.
