The portraiture capabilities of the popular Tamron MF90mm F/2.5 (Model 52BB) are further enhanced in this 90mm model with its fast F2.8 aperture. For handling ease, the lens weighs a mere 426g, making it ideal for taking advantage of its maximum macro magnification ratio of 1:1. Its 2.8 aperture and 9-bladed diaphragm help in producing soft out-of-focus backgrounds, while the optical design of the lens ensures sharp images from corner-to-corner.
