Tamron 17-70mm F/2.8 DI III-A VC RXD Fuji

Description

The Tamron 17-70mm F2.8 Fujifilm X in depth

The Tamron 17-70mm F2.8 Di III-A VC RXD (item B070X) was designed to balance a wide zoom range with high image quality while keeping a constant fast aperture. On Fujifilm X, its 25.5-105mm equivalent covers everything from moderate wide-angle to short telephoto, making it a highly practical everyday lens for both photo and video.

17-70mm range, 25.5-105mm full-frame equivalent

At 17mm you get a useful wide end for landscapes, interiors, and travel. At 70mm you have a short telephoto for portraits, details, and daily shooting. It’s a strong one-lens solution for most situations.

Constant F2.8 aperture for low light

A constant F2.8 aperture helps indoors and at dusk with more comfortable shutter speeds and lower ISO. It also gives better depth-of-field control for portraits. For video, it avoids brightness shifts while zooming.

VC stabilization with AI for photo and video

Tamron VC stabilization compensates for unwanted camera shake, improving handheld sharpness. It helps you exploit the lens performance even at slower shutter speeds, especially indoors. For video, VC uses AI to deliver more effective stabilization than conventional systems.

Fast, accurate, quiet RXD autofocus

Autofocus is driven by the extremely quiet RXD stepping motor. A built-in sensor continuously detects the focus position, providing fast and accurate AF with stable behavior on moving subjects. The quiet operation is a clear advantage for video.

Close-ups and smooth bokeh: focus from 19cm

This zoom is excellent for close-ups. Minimum focusing distance is 0.19m at wide and 0.39m at tele, with a maximum magnification of 1:4.8 (WIDE) and 1:5.2 (TELE). Great for travel details and creative shots with a soft background.

Optical quality and in-camera corrections

The optical design features 16 elements in 12 groups, including XLD and LD elements to reduce chromatic aberrations, plus aspherical elements to control spherical aberrations. It supports in-camera lens corrections for vignetting, chromatic aberration, and distortion.

Everyday-friendly design: 67mm, IF, moisture resistance, fluorine

The 67mm filter thread makes it easy to share filters. IF internal focusing prevents barrel extension and rotation while focusing, which is useful with filters. Moisture-resistant construction and a fluorine coating on the front element improve outdoor usability and make cleaning easier.

Compatibility with advanced Fujifilm features

Compatible with fast hybrid AF, eye detection, DMF, in-camera lens corrections, and firmware updates via the camera.
