90mm · f/2.8
The Tamron SP AF 90mm F/2.8 Di Macro is a sharp, affordable macro lens with excellent optical performance, rivaling Nikon's Micro-Nikkor. It offers 1:1 magnification and good infinity focus. Build quality is solid with a metal mount, though the barrel extends significantly at 1:1. The focus ring has a nice feel, but AF can be slow. It suits macro and portrait photographers seeking a budget-friendly, high-quality lens (PhotoReview).
