Compact Wide-Angle Prime with Half Life-Size Macro Capability – 1:2 Maximum Magnification Ratio, Ultra-Close 4.7″ Minimum Focusing Distance, Modestly Bright f/2.8 Maximum Aperture, Three Low Dispersion (LD) Elements & One Molded Glass Aspherical Element, BBAR (Broad-Band Anti-Reflection) Coating, OSD (Optimized Silent Drive) Stepping AF Motor with Full-Time Manual Focus Override, Rounded 7-Blade Diaphragm, Moisture-Resistant Sealing with Protective Fluorine Front Coating, Full-Frame & APS-C Compatibility, Native Sony E-Mount (Excellent Condition)

The Tamron 24mm f/2.8 Di III OSD M 1:2 is an ultra-portable wide-angle prime lens engineered specifically for full-frame Sony E-mount mirrorless cameras. Delivering a classic 24mm field of view favored by landscape photographers, street documentarians, interior shooters, and travel vloggers, it combines optical precision with an exceptionally lightweight form factor. The f/2.8 maximum aperture strikes an ideal balance between low-light capability and a compact profile, making it a reliable everyday prime for handheld street work, travel kits, and gimbal-mounted video production.

Distinguishing this wide-angle prime from conventional 24mm optics is its close-up versatility, achieving a half life-size 1:2 maximum magnification ratio at a minimum focusing distance of just 4.7 inches. This allows photographers to isolate small foreground subjects with broad environmental perspective. The optical design incorporates three Low Dispersion (LD) elements to reduce chromatic aberrations and color fringing, alongside a molded glass aspherical element to eliminate spherical aberrations and field distortion for edge-to-edge sharpness. Tamron’s BBAR (Broad-Band Anti-Reflection) coating prevents internal reflections, flare, and ghosting to maintain rich contrast and color accuracy in challenging backlit environments. Autofocus is powered by an OSD (Optimized Silent Drive) stepping motor for quiet, accurate focusing with full-time manual override, while internal moisture-resistant seals and a protective front fluorine coating ensure dependable operation in adverse conditions.
