Tamron 24mm f/2.8 Di III OSD M 1:2 Lens for Sony E

The Tamron 24mm f/2.8 Di III OSD M 1:2 is a wide-angle prime lens designed for Sony E-mount full-frame mirrorless cameras, offering a 1:2 maximum magnification ratio that makes it well-suited for close-up and macro-style photography alongside everyday wide-angle shooting. The optical construction consists of 10 elements in 9 groups, incorporating one Low Dispersion (LD) element and one Glass-Molded Aspherical element to control chromatic aberration and distortion. Autofocus is driven by Tamron’s OSD (Optimized Silent Drive) stepping motor, which provides quiet and smooth focus operation compatible with Sony’s Fast Hybrid AF system including Eye AF. The minimum focusing distance is 11cm (approximately 4.3 inches), enabling the close focusing capability central to this lens’s design. The aperture diaphragm features 7 rounded blades for smooth bokeh rendering. The lens is moisture-resistant with a sealed construction and includes a fluorine coating on the front element to repel water and smudging. At 215g, it is a compact and lightweight option within the Sony E-mount ecosystem, and the 67mm filter thread is shared across Tamron’s 17mm, 24mm, and 35mm f/2.8 Di III OSD primes.
