  • Camera-based lens unit firmware updates*

*Features vary by camera. Please consult your camera’s instruction manual for details.

Sophisticated high-resolution optics

 

LD (Low Dispersion) Elements GM (glass-molded aspherical) Elements
BBAR (Broad-Band Anti-Reflection) Coating 2:1 Close Focus

Superb high-resolution performance that matches the latest high-resolution image sensors achieved thanks to the sophisticated optical formula created with the latest lens design technologies. Optimal arrangement of LD (Low Dispersion) and GM (glass-molded aspherical) lens elements results in exceptionally high rendering performance from edge to edge, while minor distortions sometimes common in wide-angle lenses are corrected using in-camera functions.

Additionally, Tamron’s legendary BBAR (Broad-Band Anti-Reflection) Coating effectively reduces ghosting and flare.

With excellent resolving power achieved through uncompromising optical performance and camera-based distortion correction, this lens can be used with complete confidence for a wide range of applications from casual family snaps to serious professional photography.

Enhanced close-focusing capability

Excellent minimum close focus of only 0.11m results in a maximum magnification ratio of 1:2 so you can fill the frame, even when shooting small objects. You’ll never again be frustrated because you cannot get close to an object while shooting.

This remarkable performance allows the creation of compositions that exploit the dramatic perspective by keeping your main subject close in the foreground. With a fast F/2.8 aperture you can leverage the power of a beautifully blurred background bokeh as well.

With dramatic closeup shooting performance for full-frame lenses, this lens unleashes an unprecedented level of shooting freedom.

Silent autofocus driven by OSD (Optimized Silent Drive) DC motor

The AF drive system employs an OSD to ensure quiet operation.

In comparison to conventional AF types with built-in DC motors, Tamron was able to greatly reduce the drive noise as well as vastly improve AF performance and speed. The lower ambient noise level is sure to be appreciated by video shooters.

Overall, this fixed focal lens series provides superlative AF precision for exact focus even when shooting moving subjects, as well as outstanding accuracy and tracking capability.

Additionally, this fixed focal series supports various AF features offered by certain Sony cameras, including Fast Hybrid AF, Eye AF, and Direct Manual Focus (DMF) to ensure a pleasant shooting experience.

Extreme portability, versatility & comfort

 

64mm overall length Lightweight
Internal Focus 67mm Filter Thread

Designed to match lightweight, full-frame mirrorless cameras. This lens sports an overall length of just 64mm (2.5 in). Comfortable, portable, highly maneuverable and amazingly easy to use and compose.

Because the overall length does not change when focusing, you can get as close to an object as you need to without fear of accidentally bumping the front element.

Released together with the 24mm F/2.8 Di III OSD M1:2 (Model F051), and the 35mm F/2.8 Di III OSD M1:2 (Model F053), this lens series features the same 67mm filter diameter as Tamron’s zoom lenses for full-frame mirrorless cameras to significantly reduce cost and packing space when working with PL, ND and other filters. Even the front lens caps are the same size, eliminating the hassle of sorting caps when switching lenses.

Weighing in at only 220g the lens is exceptionally light, allowing photographers to enjoy shooting comfortably without hesitating about whether to carry the lens.

Moisture-Resistant Construction and Fluorine Coating

Environmental seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

Also, the front surface of the lens element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, moisture or oily fingerprints, allowing for much easier maintenance.
