I want to get a Nikon micro f/2.8 60mm lens (like the one Jim Brandenburg used to take one of his '1 photo a day for 90 day close- ups). I've noticed reading the posts that people use the word 'macro' and 'micro' when they talk about the same thing. I'm a little confused, is micro and macro the same? Please explain. Also, what is the difference in a close-up between a 60mm micro lens and a 105mm micro lens? Is it that with a 105 can stay further away from your subject than you would with a 60mm micro?
