- Compact, ultra-wide-angle lens
- High-performance AF with RXD motor
- One XLD and two LD lens elements
- Superior close-up capability
Engineered exclusively for mirrorless cameras, the Tamron 17-28mm f/2.8 Di III RXD lens delivers outstanding optical performance in a compact size. The AF drive uses RXD motor technology to allow for quiet, smooth operation, and three optical lens elements help minimize chromatic aberrations. The ultra-wide-angle Tamron 17-28mm is not only suitable for landscape and architectural photography, but short MODs at both ends provide powerful close-up shots.
Small size, high usability
An extremely usable, ultra-wide-angle lens, the Tamron 17-28mm f/2.8 Di III RXD is just 3.9 inches (99mm) long and weighs in at less than one pound (420g), so can go just about anywhere. The overall length of the lens doesn’t change during zooming, making it easy to handle and resulting in more consistent shooting. It also shares the same filter diameter as the Tamron 28-75mm, so polarizers and lens caps can also easily be shared.
The Rapid eXtra-silent stepping Drive (RXD) in the Tamron 17-28mm f/2.8 Di III RXD controls the rotational angle of the motor using a precision actuator, directly driving the focusing lens without passing through a reduction gear, making this lens exceptionally quiet and fast—so you can shoot video without picking up any ambient drive sounds.
Clear, accurate color
One Extra-Low Dispersion (XLD) element and two Low Dispersion (LD) in the Tamron 17-28mm f/2.8 Di III RXD help minimize chromatic aberrations and color fringing, improving color accuracy. Lens surfaces are treated with Tamron’s proprietary Broad-Band Anti-Reflection (BBAR) coating, helping to preserve a crisp image quality while reducing ghosting and flaring.
Get ready for a close-up
Featuring a Minimum Object Distance (MOD) of 7.5 inches and a magnification ratio of 1:5.2 at the wide end and 10.2 inches/1:6 at the tele end, the Tamron 17-28mm f/2.8 Di III RXD lens maximizes the perspective and depth-of-field unique to ultra-wide-angle lenses.
