I wanted a 180mm for close up work on a copy stand. It may not always be macro work, but all will be done at much close than infinity. I can not afford a 180 specifically designed for macro, so I was wondering which 180mm would work best for close up work. I believe I also would want it to be multicoated as the lights I am using are bright and often at either side of the lens..... if someone thinks a single coated lens would not be affected by such a lighting situation please feel to let me know and I may feel good about getting a g-claron. I am also considering a 210mm.
