Tamron's APS-C constant-aperture zoom expands to two new mounts. The 17-70mm f/2.8 VC RXD launches for Nikon Z and Canon RF on July 2 at $749.

Tamron has added Nikon Z and Canon RF mount support to its popular 17-70mm f/2.8 Di III-A VC RXD ([Model B070](http://tamron.com/global/consumer/lenses/b070/)), an APS-C standard zoom previously available for Sony E and Fujifilm X mounts. Both versions go on sale July 2, 2026 at $749.

The lens covers a 17-70mm focal length, equivalent to 25.5-105mm on Nikon Z or 27.2-112mm on Canon RF, with a constant maximum aperture of f/2.8 and a 4.1x zoom ratio that Tamron says is the widest among f/2.8 standard zooms for APS-C mirrorless cameras. Built-in Vibration Compensation (VC) handles camera shake for both stills and video, while the RXD autofocus motor is designed to be fast and quiet with focus breathing suppressed.

## Working up close

Close-focus performance is worth talking about: minimum object distance is 0.19 m (7.5 in) at the wide end and 0.39 m (15.4 in) at tele, giving maximum magnification of 1:4.8 and 1:5.2 respectively. Optical construction is 16 elements in 12 groups, with a 9-blade circular diaphragm.

The Canon RF version adds physical AF/MF and VC ON/OFF switches that the Z version lacks. Both Nikon Z and Canon RF variants support firmware updates via Tamron Lens Utility. The lens has moisture-resistant construction and fluorine coating on the front element. Filter diameter is 67mm across all versions.

Dimensions and weight differ slightly by mount: the Nikon Z version measures 121.3 mm (4.8 in) long and weighs 540 g (19 oz); the Canon RF version is 117.3 mm (4.6 in) and 530 g (18.7 oz). Both ship with a flower-shaped hood, front cap, and rear cap.
