Tamron announced a pair of DSLR primes SP 85mm f/1.8 Di USD and SP 90mm f/2.8 Di 1:1 Macro for Canon, Nikon and Sony A-mount. Both lenses sport Tamron’s new lens design. Tamron also announced a lens tuning and firmware update system, similar to the Sigma system, that allows you to update the lens firmware using a USB connection.

Tamron SP 85mm f/1.8 Di USD Lens (Price not yet available) is a short-telephoto prime designed for full-frame Sony A-mount DSLRs. Incorporating both Low Dispersion and Extra Low Dispersion glass into the optical design, this lens is adept at reducing chromatic aberrations and color fringing for a high degree of clarity and color accuracy, as well as sharpness and resolution. BBAR and eBAND coatings have also been applied to minimize flare and ghosting for increased contrast when working in strong lighting conditions, and a rounded nine-blade diaphragm contributes to a pleasing bokeh quality to benefit shallow depth of field imagery. Classic in terms of focal length yet optimized for the recent breed of high-resolution DSLRs, this portrait-length prime melds a familiar perspective with contemporary performance.

Tamron SP 90mm f/2.8 Di 1:1 Macro Lens (Pre-order here for $649) is a short telephoto prime designed for full-frame Sony A-mount DSLRs. Offering a life-size maximum magnification ratio of 1:1, this lens benefits working with small and nearby subjects and employs a Floating System for maintained image quality throughout the 11.8″ to infinity focusing range. One Low Dispersion and two Extra Low Dispersion glass elements are incorporated into the optical design to minimize chromatic aberrations and color fringing for clean, consistent sharpness and clarity throughout the magnification range. BBAR and eBAND coatings have also been applied to minimize flare and ghosting for increased contrast when working in strong lighting conditions, and a rounded nine-blade diaphragm contributes to a pleasing bokeh quality to benefit shallow depth of field imagery. As an update to the classic 90mm macro, this enhanced version is well-suited to the high-resolution crop of DSLRs and blends timeless appeal and functionality with current imaging performance.
