Versatile Zoom Range and Bright Design

The Tamron 17-70mm f/2.8 Di III-A VC RXD is a 25.5-105mm-equivalent lens for APS-C-format FUJIFILM X-mount mirrorless cameras. This versatile zoom range is perfect for everyday shooting, while the fast f/2.8 constant maximum aperture provides great low-light performance and depth-of-field control. Specialised optics, including aspherical and low dispersion elements, ensure sharpness, clarity and accurate colour reproduction. Tamron's BBAR coating reduces flare and ghosting for better contrast in backlit or harsh lighting conditions.

Adding to the versatility of the zoom design is a Vibration Compensation image stabilisation system, which reduces the appearance of camera shake for steadier photo and video recording in low-light conditions. Also benefitting handling, an RXD stepping motor enables quick, near-silent autofocus performance along with full-time manual focus override and a minimum focusing distance of 7.5". Suiting this lens's use in inclement weather conditions, it also features a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging.

Features

Versatile zoom is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and covers wide-angle to short-telephoto fields of view with its 25.5-105mm equivalent focal length range.

Bright constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over the depth of field.

Two moulded glass aspherical elements and one hybrid aspherical element help to correct distortion and spherical aberrations to achieve a high degree of sharpness and accurate rendering.

Two LD (Low Dispersion) elements greatly reduce colour fringing and chromatic aberrations throughout the zoom range in order to realize improved clarity and colour accuracy.

BBAR (Broad-Band Anti-Reflection) Coating has been applied to individual elements in order to suppress internal reflections, flare, and ghosting to achieve greater contrast and colour fidelity when working in strong lighting conditions.

RXD (Rapid eXtra-silent stepping Drive) autofocus motor delivers impressively quiet, quick, and smooth focusing performance to suit both stills and video applications. This focusing system also offers a minimum focusing distance of just 7.5" and a 1:4.8 maximum magnification for working with close-up subjects. Full-time manual focus override is also possible, and it is compatible with Sony's Direct Manual Focus function or fine-tuned manual control.

VC image stabilisation helps to minimize the appearance of camera shake for more effective handheld shooting in difficult lighting conditions.

A moisture-resistant construction benefits this lens' use in inclement conditions, and a fluorine coating has also been applied to the front lens element to protect against dust, dirt, and smearing.

The rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
