Sony Shooters: Tamron 28-200mm f/2.8-5.6

Tamron announced this week a new zoom lens compatible with Sony E-Mount full-frame mirrorless. The Tamron 28-200mm f/2.8-5.6 Di III RXD lens will be the first all-in-one-zoom to achieve a maximum aperture of F2.8 at the wide-angle end.

The folks at Tamron are especially excited for this release, saying, in a press release, the lens breaks conventional limitations by broadening the horizons of photographic possibilities. 

“This zoom lens writes a new chapter in the history of the all-in-one zoom lens,” said Tamron. “The new 28-200mm f/2.8-5.6 is a distillation of all Tamron’s accumulated all-in-one zoom expertise and has been specifically developed as an all-in-one zoom for daily use on a full-frame mirrorless camera.” 

The Sony E-mount full-frame lens offers f/2.8 at 28mm, f/3.5 at 50mm, f/4.5 at 100mm, and f/5.6 at 150mm and longer.

Inside, the lens contains 18 elements in 14 groups, including GM (Glass Molded Aspherical), hybrid aspherical, XLD (eXtra Low Dispersion) and LD (Low Dispersion) lens elements precisely arranged to effectively control chromatic and other aberrations, enabling high resolving power. 

Meanwhile, the BBAR (Broad-Band Anti-Reflection) Coating provides powerful anti-reflection properties to effectively reduce ghosting and flare, resulting in clear and crisp images. 

In-camera correction features are utilized to mitigate distortion and shading to achieve uniformly high image quality from edge-to-edge at all zoom settings. 

All of this creating a “new standard among existing all-in-one zoom lenses,” according to Tamron. 


Other features and specs of the lens include a weight of 20.3oz, a length of 4.6 inches, a filter diameter of 67mm, a minimum object distance of 7.5″ on the wide end to 31.5″ on the telephoto end (max magnification ratios of 1:3.1 and 1:3.8, respectively), a fast and quiet RXD stepping motor, and a Zoom Lock switch.

Mounted on a mirrorless camera, the lens is compatible with features such as Fast Hybrid AF, Eye AF, Direct Manual Focus (DMF), in-camera lens correction, and camera-based lens firmware updates.

The lens was set to be available starting on June 25th but could be delayed, according to Tamron, due to COVID-19. The cost, when available, will be $729.
