Tamron 24mm f/2.8 Di III OSD M1:2 Full-Frame Lens for Sony E-Mount, Black Review

The Tamron 24mm f/2.8 Di III OSD M1:2 is a compact prime lens designed for Sony E-mount full-frame mirrorless cameras. At $165, it sits at the budget end of the 24mm prime category, offering a moderately fast f/2.8 aperture and a half-macro magnification ratio (1:2) that sets it apart from many wide-angle primes. The OSD (Optimized Silent Drive) motor promises quiet autofocus, making it suitable for both stills and video work. At 67mm filter diameter and Tamron's typically lightweight construction, it should balance well on most Sony bodies.

This lens is part of Tamron's trio of affordable f/2.8 primes (20mm, 24mm, and 35mm) aimed at shooters who want sharpness and close-focusing capability without the bulk or cost of faster glass. The 24mm focal length is versatile for landscapes, environmental portraits, and street photography, while the 1:2 macro spec adds flexibility for detail and product work. Build quality and autofocus performance will be the key questions for anyone considering this over Sony's own 24mm or third-party alternatives.
