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

Blending a sleek form-factor with a versatile working range, the 28-75mm f/2.8 Di III RXD from Tamron is a full-frame-compatible lens for Sony E-mount mirrorless cameras. Spanning wide-angle to portrait-length, a constant f/2.8 maximum aperture complements this range and affords increased control over depth of field along with enhanced low-light performance.

The Model A036 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 TamronÕs 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.

Tamron 28-75mm f/2.8 Di III RXD Lens 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.
