Tamron 17-70mm F2.8 Di III-A VC RXD Lens for Nikon Z: APS-C 17-70mm F2.8 with VC for Nikon Z
The Tamron 17-70mm F2.8 Di III-A VC RXD Lens for Nikon Z (Model B070) is an APS-C 17-70mm F2.8 standard zoom for Nikon Z with VC image stabilisation, RXD autofocus and a 4.1x range. Available from Tamron at Camerahaus.
Who Is This Made For?
The 17-70mm F2.8 is for Nikon Z DX shooters who want one bright everyday zoom for video and stills.
4.1x constant F/2.8 zoom for APS-C
Covers 17-70mm (about 25.5-105mm equivalent) at a constant F/2.8, the widest zoom range in its class, so one lens handles street, portrait and landscape work.
Built-in VC stabilisation
Tamron's VC mechanism steadies hand-held stills in low light and is tuned for video, with AI-assisted compensation that adapts to how you are shooting.
Quiet, accurate RXD autofocus
The RXD stepping motor drives the focus group directly and silently, suiting both fast stills and video recording.
Close focus down to 0.19 m
Focuses as close as 19 cm at the wide end and 39 cm at the long end, giving table-top and detail shots without a dedicated macro lens.
Suppressed focus breathing
The optical design limits changes in angle of view when focus shifts, keeping focus pulls natural in video.
Light, weather-resistant build
At 540 g with moisture-resistant seals and a fluorine-coated front element, it is built for everyday and travel use.
Firmware updates via TAMRON Lens Utility
The Nikon Z version accepts firmware updates through Tamron's Lens Utility software without going through the camera.
