Based on reviews I was thinking of buying the Tokina ATX PRO 100 for floral macro photos.So far I haven't found one good floral photo on line taken with this lens. I have seen far better photos taken with common old Soligors and JC Penneys . So far the best small floral photos I've seen on line have been taken with vintage Elicar 90 mm lenses. I may have just been unlucky in my search. Is the Elicar 90 mm better for micro than the Tokina ATX Pro? Are there any better choices for Nikon or Pentax out there under $500.00 ?
