APS-C mirrorless zoom with constant f/2.8

The Tamron B070 covers 17-70mm on Fujifilm X-mount bodies, delivering a 4.1x zoom range with a fixed maximum aperture of f/2.8 throughout. It is built for photographers and videographers who need a single lens for wide-angle to short-telephoto work on APS-C mirrorless cameras. The 67mm filter thread matches many other Tamron mirrorless lenses for filter compatibility.

Vibration Compensation tuned for sustained video

The VC mechanism uses AI-assisted stabilisation optimised for continuous video recording as well as stills. It reduces camera shake during extended handheld sessions without the drift that can appear in simpler systems. The RXD stepping motor drives autofocus quietly and maintains minimal focus breathing so framing stays consistent during long takes.

Fujifilm X-mount APS-C image circle defines

The lens projects an image circle sized for APS-C sensors, giving a full-frame equivalent view of 25.5-105mm. It cannot illuminate a full-frame sensor without vignetting, so it is not suited to cameras with larger formats. The 7.5m minimum focus distance at the wide end sets the closest working range for close-up detail.

Questions about this item

Does the VC image-stabilisation stay effective during long video sessions without overheating?

The Vibration Compensation mechanism is optimised for both stills and video and uses AI assistance for footage, so it remains active during extended recording without thermal issues.

What camera mount must I already own to attach this lens?

The lens uses the Fujifilm X mount, so you need an APS-C mirrorless body with that bayonet such as an X-T or X-S series camera.

Will the 67 mm filter threads match the circular polarisers and ND filters I already use on other Tamron mirrorless lenses?

Yes, the 67 mm filter diameter is shared across most Tamron mirrorless lenses, so your existing 67 mm filters screw on directly.
