Tamron 180mm f/3.5 Di LD IF Macro 1:1 SP AF review by MediaGuru
23 November 2012
Summary: I spent countless hours researching for a good macro lens and basically had it narrowed down to the Sigma 70mm, Tamron 90mm and 180mm. I read complaints about how close you have to get with the 70 or 90mm lenses and decided that any extra distance I could place between myself and shy animals and bugs would be nice (this lens is supposed to be able to focus at 18.5 inches). I am not sure if this is normal or typical of a macro lens, but I was able to focus at 10 inches.
Pros: Excellent IQ, smooth focus ring, very little distortion, little to no chromatic aberration or vignetting
Cons: Wiggles ever so slightly when mounted to my Sony A57
