Sony Tamron 20mm F2.8 Di III OSD M1:2 Super Wide Angle Mirrorless Lens AFF050S-700

Developed under the concept of “letting as many as possible learn the joy of prime lenses in a more accessible way,” Tamron Sony FE 20mm Prime Lens strikes a balance between gorgeous image rendering and superior operation. We matched the same filter size (Ø67mm) as the two previously launched zooms and achieved our aim of compactness. Furthermore, the lens is all capable of focusing very close, to an unprecedented in this category magnification ratio of 1:2. Other features include Moisture-Resistant Construction (for outdoor shooting) and a Fluorine Coating on the front element for easy maintenance and fingerprint removal. The lens also supports various camera features offered by certain Sony cameras, such as Fast Hybrid AF and Eye AF, and offer a multitude of advanced functions to ensure a pleasant shooting experience and fantastic results.

Product Highlights

Enhanced close-focusing capability expands lens usefulness and versatility

The Tamron Sony FE 20mm Prime Lens focuses very close. The MOD (Minimum Object Distance) for the 20mm lens is 4.3 inches. Plus, the maximum magnification ratio is 1:2. This remarkable performance allows users to create compositions that emphasize perspective (closer subjects are larger and distant ones are smaller) and that are unique to wide-angle lenses.

Being able to get in close is one of the most desirable specifications for a wide-angle lens. With dramatic closeup shooting performance for full-frame lenses, this lens unleashes an unprecedented level of shooting freedom. Plus, by moving close to the subject, strongly blurred backgrounds are easier to attain.

A compact, lightweight 67mm filter diameter system offering excellent portability

Weighing in at 7.8 oz, the Tamron Sony FE 20mm lens is exceptionally light, allowing photographers to enjoy shooting comfortably without hesitating about whether to carry the lens. Meanwhile other lenses in Tamron’s lightweight full-frame mirrorless series such as the 28-75mm F/2.8 (Model A036) standard zoom or 17-28mm F/2.8 (Model A046) ultra-wide-angle zoom make the perfect companions to broaden the range of shooting possibilities.

As testament to its compactness, the 20mm lens features the same 67mm filter diameter as Tamron’s zoom lenses for full-frame mirrorless cameras. This significantly reduces 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. These features combine to produce a highly convenient and mobile system that adds more fun to photography.

Superb high-resolution performance that matches the latest high-resolution image sensors

The sophisticated optical formula created with the latest lens design technologies boasts exceptionally high rendering performance from edge to edge thanks to the optimal arrangement of LD (Low Dispersion) and GM (glass-molded aspherical) lens elements. Any remaining 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.

Consistent 64mm (2.5 in) overall length facilitates ease-of-use

The Tamron Sony FE 20mm Prime Lens is just 2.5 inches long. Achieving excellent balance with Sony E-mount cameras, this compact lens employ a front element extension system but are designed to maintain the same exterior length during focusing operations. Therefore, there is less chance of an extended front element accidentally coming into contact with a subject during closeup shooting. And optional manual focusing is easier because the focus ring is positioned toward the front of the lens within natural reach of the thumb and index finger.

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

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. These protective features are keenly important for lenses that allow you to get in close to a subject. 

Compatible with main camera-specific features and functions

The Tamron Sony FE 20mm Prime Lens is compatible with many of the advanced features that are specific to certain mirrorless cameras. These include the following:

-Fast Hybrid AF

-Eye AF

-Direct Manual Focus (DMF)

-In-camera lens correction (shading, chromatic aberration, distortion)

-Camera-based lens unit firmware updates
