Which way to go , I love and have much to learn on macro shooting. I have a budget of $600 . I own an Oylmpus E -620 a 4/3 and a newly purchased Nikon D7100 . After reviewing I narrowed it down to A Nikkor 85 f/3. with VR , compared to a Zuiko 60mm. Based on the body and pixels where to I go for the best results and for enlargement of the prints. This lenses will also be used for serious portrait shots . The Nikon crop factor is I beleve 1.5 and with the Olympus is 2.. There are those that hold a 50mm is the way to go . but with somw macro I need to consider the distance to the subject as being accessible and without causing interference .Any suggestions would be helpful .
