Tamron 28-75mm f2.8
Superb optical performance with the Tamron 28-75mm f2.8, including both outstanding image quality and the beautiful background blur effects (bokeh) provided by a fast F2.8 aperture
The Tamron 28-75mm f2.8 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.
Moisture-Resistant Construction and Fluorine Coating for weather protection
The Tamron 28-75mm f2.8 has environmental seals 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.
