Just coming off the success of their 70-80mm f/2.8 Lens for Sony, Tamron has now announced their new Tamron 28-200mm f/2.8-5.6 Di III RXD lens, the world’s first all-round zoom lens that offers f/2.8 at the wide end.
Designed for the Sony E-mount full frame cameras like the 70-180mm, the new 28-200mm lens (Model A071) reasserts Tamron’s Leading role in pioneering all-in-one lenses, just like the company did back in 1992 with the AF 28-200mm f/3.8-5.6 Aspherical (Model 71D).
According to 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. We chose Model A071 as the model name as a nod to “71” representing the world’s original compact all-in-one zoom”.
Tamron also said the goal of the new A071 was “Breaking conventional limitations and broadening the horizons of photographic possibilities.”
The 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 are 18 elements in 14 groups that include GM (Glass Molded Aspherical), hybrid aspherical, XLD (eXtra Low Dispersion), and LD (Low Dispersion) lens elements. These are “precisely arranged to effectively control chromatic and other aberrations, enabling high resolving power,” Tamron says.
On the front of the moisture-resistant lens is BBAR (Broad-Band Anti-Reflection) Coating that reduces ghosting and flare. There’s also a fluorine coating that repels oil and water.
When 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.
Tamron 28-200mm f/2.8-5.6 Di III RXD lens is set to be available starting on June 25th with a price tag of $729 but the company says “due to the spread of COVID-19, the release date or the product supply schedule could be delayed”.
