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

The Tamron A036 28-75mm f/2.8 Di III RXD, a high-speed standard zoom lens, is specifically designed for Sony E mirrorless cameras. It is an amazingly lightweight and compact lens with fast constant aperture and high-resolution and contrast. It utilizes specialized glass elements, including an XLD lens, that control various aberrations to produce stable resolution across the entire zoom range. This is compact and lightweight lens weighing only 19.4 ounces.

Superb Optical Performance

The Tamron 28-75mm’s optical design utilizes 15 elements in 12 groups, including a special XLD (eXtra Low Dispersion) element, LD (Low Dispersion) element, GM (Glass Molded) aspherical element, and two hybrid aspherical lens elements. Plus, the lens also employs BBAR (Broad-Brand Anti-Reflection) Coatings that effectively reduces ghosting and flare, even when shooting in backlit conditions. In addition, the lens’ nine-blade circular diaphragm design provides beautiful soft portrayal at wide open aperture (f/2.8) to a clear and sharp image when stopped down.

RXD Stepping Motor AF Unit

The focus 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 Autofocus (AF) control. This results in quick and precise AF operation that helps maintain pin-sharp focus on continually moving subjects or when filming video. Also, the AF motor gives a near-silent operation during video recordings.

Exciting, Ergonomically Superb Next-generation Design

The mirrorless-oriented design adheres to a new human touch lens design concept. As signified by the Luminous Gold brand ring, careful attention to detail has produced an optimum shape characteristic of a Tamron lens, whether on its own or attached to a camera body. This design emphasizes brand identity combined with ease of operation.

Wide-Angle and Telephoto

The A036 28-75mm achieves a MOD of 7.5 inches at the 28mm wide-angle end which delivers a maximum image magnification of 1:2.9. The ultra-wide angle focal length and constant f/2.8 aperture, as well as a close focus range of 7.5 inches at the wide-angle end, combine for superb optics and quality. At the 75mm telephoto end, the 15.3-inch MOD provides an image magnification of 1:4, thereby enabling close-up shooting with a pleasantly blurred background similar to a macro lens.

Moisture-Resistant Construction

The lens comes sealed near the mount area and other critical locations that protect its optical elements from moisture and rain drops. This moisture-resistant construction makes the lens suitable for shooting outdoors under adverse weather conditions. The front of the lens is coated with a protective fluorine coating that provides protection against dirt, moisture, and oily fingerprints. You can easily wipe and the lens surface to clean.
