    Overview

    The Tamron SP 300mm f/2.8 LD IF Adaptall-2 (model 60B) is a professional-grade manual-focus telephoto lens with low dispersion glass and internal focusing. Optically, it is sharp when stopped down but may be soft wide open, according to one review. Build quality is solid, with a compact design for its class, though it is heavy. It suits photographers who can work with manual focus and want a fast 300mm on a budget, particularly for stage or sports work.
