The versatile, compact and lightweight Tamron 28-75mm F/2.8 Di III RXD full-frame zoom lens delivers 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.
The Tamron 28-75mm full-frame 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 fully match with various camera-specific features including the in-camera lens correction and Direct Manual Focus (DMF) system features of Sony cameras.
Superb optical performance
This 28-75mm features a new design that leverages the advanced image quality of the latest full-frame mirrorless cameras. To balance beautiful bokeh with high image quality, the optical formula (15 elements in 12 groups) 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. In addition, incorporating the nine-blade circular diaphragm design, the lens will perform in versatile situation, providing beautiful soft portrayal at wide open aperture to a clear and sharp image when stopped down.
Comfortably 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), the A036 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.
All-new “RXD” stepping motor AF unit
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.
Moisture-Resistant Construction and Fluorine Coating for weather protection
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.
