Tamron 28-75mm f/2.8 Di III RXD Lens for Sony E Mount

The Tamron 28-75mm f/2.8 Di III RXD Lens for Sony E Mount delivers superb optical performance, including both outstanding image quality and beautiful background blur effects (bokeh) only possible with a fast aperture, thanks to a new optical system designed specifically for mirrorless cameras. In addition to shooting portraits with creative, defocused backgrounds, photographers can enjoy dynamic wide-angle expressions like never before thanks to a Minimum Object Distance (MOD) of 0.19m (7.5 in) at the wide-angle zoom setting.

The lens incorporates an all-new high-speed and precise AF driving system. The RXD (Rapid eXtra-silent stepping Drive) strikes a balance between speed and silent operation, making it perfect for both video and still image capture. The lens also features Moisture-Resistant Construction that is useful in outdoor photography, plus hydrophobic Fluorine Coating that is highly resistant to fingerprints and dirt. It will also fully match with various camera-specific features including the in-camera lens correction and Direct Manual Focus (DMF) system features of Sony cameras, enabling this new zoom to take full advantage of the advanced functions that ensure comfortable user experiences.

Product Features in Detail

Lightweight and compact
Extra emphasis was placed on creating a high speed, fast aperture zoom lens in a compact and lightweight design because standard-range zooms are generally the most frequently used. Weighing only 550g (19.4 oz) with a length of just 117.8mm (4.6 in), it enables photographers to enjoy the mobility provided by a compact, lightweight, full-frame mirrorless camera in all situations from casual snapshots to stunning portraits and dramatic landscape photography.

Lens composition
The optical formula includes a special XLD (eXtra Low Dispersion) element, LD (Low Dispersion) element, GM (Glass Molded Aspherical) element and two hybrid aspherical lens elements in the optimal arrangement to correct aberrations and reduce the overall lens size. The lens also employs Tamron’s BBAR (Broad-Band Anti-Reflection) Coating that boasts exceptional anti-reflection performance throughout the entire zoom range, even when shooting in backlit conditions.

Smooth and quiet AF
The AF drive incorporates a sensor that accurately detects the position of the lens and an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit optimized for AF control. This achieves quick and precise AF operation, allowing users to maintain pin-sharp focus on continually moving subjects or when filming video. Additionally, the AF motor is exceedingly quiet, virtually eliminating extraneous AF drive sounds during video recording.

Minimum Object and Working Distance
It breaks from the convention that the MOD of a zoom lens must be fixed throughout the focal range and achieves a MOD of 0.19m (7.5 in) at the 28mm wide-angle end which delivers a maximum image magnification of 1:2.9. The working distance of just 5.7cm (2.24 in) from the front element allows photographers to enjoy close-up shooting that emphasizes the sense of perspective unique to wide angles. At the 75mm telephoto end, the 0.39m (15.3 in) MOD provides an image magnification of 1:4, thereby enabling close-up shooting with a pleasantly blurred background similar to a macro lens.

Protection against harsh elements
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.
