Compact Wide-Angle Prime with Macro Capability – Half Life-Size 1:2 Maximum Magnification Ratio, Close 5.9″ Minimum Focusing Distance, Modest f/2.8 Maximum Aperture, Low Dispersion (LD) & Molded Glass Aspherical Elements, 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 35mm f/2.8 Di III OSD M 1:2 is a compact, highly versatile wide-angle prime lens engineered specifically for full-frame Sony E-mount mirrorless cameras. Balancing optical performance with a portable form factor, it offers an accessible 35mm perspective favored by street documentarians, travel photographers, environmental portrait artists, and everyday creators. The f/2.8 maximum aperture strikes an ideal compromise between low-light capability and a lightweight, unobtrusive chassis that facilitates discreet, all-day handheld shooting.

Distinguishing this prime from standard 35mm optics is its close-up capability, delivering a half life-size 1:2 maximum magnification ratio at a minimum focusing distance of just 5.9 inches. This enables dramatic close-up perspectives with broad environmental context. The optical layout incorporates one Low Dispersion (LD) element to combat chromatic aberrations and color fringing, alongside a glass molded aspherical element that controls distortion and spherical aberrations for crisp edge-to-edge sharpness. Surface reflections, flare, and ghosting are suppressed by Tamron’s BBAR (Broad-Band Anti-Reflection) coating, preserving contrast in backlit environments. Autofocus is handled by an OSD (Optimized Silent Drive) stepping motor for quiet, precise focusing and full-time manual override, while internal moisture-resistant seals and a fluorine-coated front element protect the assembly against the elements.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Half Life-Size 1:2 Macro Reproduction: Focuses down to 5.9″ to capture fine close-up details with wide-angle contextual backgrounds.

Portable f/2.8 Form Factor: Balances light-gathering potential with a lightweight footprint suited for walkaround street, documentary, and travel work.

Advanced Optical Correction: Employs an LD (Low Dispersion) element and a molded glass aspherical element to eliminate chromatic aberrations and spherical distortions.

BBAR Multi-Coating: Minimizes flare and ghosting to maintain rich color fidelity and high micro-contrast under challenging lighting.

Quiet OSD Stepping Motor: Delivers smooth, near-silent autofocus tracking suitable for candid stills and video, backed by full-time manual focus override.

Rounded 7-Blade Iris: Produces pleasing circular bokeh highlights and smooth, natural out-of-focus background transitions.

Weather-Sealed Reliability: Moisture-resistant gaskets protect internal components from harsh weather, paired with a smudge-resistant fluorine front coating.

APS-C Format Versatility: Functions as a 52.5mm equivalent standard normal prime when mounted to Sony APS-C mirrorless camera bodies.

COMPREHENSIVE CAMERA COMPATIBILITY

Full-Frame Sony E-Mount Cameras: Fully compatible with full-frame Sony mirrorless bodies (including Sony a7 IV, a7R V, a7C II, a7CR, a7S III, a9 III, and a1).

APS-C Sony E-Mount Cameras: Mounts natively to Sony APS-C bodies (such as Sony a6700, a6600, a6400, and ZV-E10 series), providing an effective 52.5mm standard focal length equivalent.
