Versatile 17-70mm f/2.8 zoom for APS-C Sony E

The Tamron B070 is a fast standard zoom lens built for Sony APS-C mirrorless cameras. Its constant f/2.8 aperture covers a 17-70mm range, equivalent to 25.5-105mm on full frame. A 4.1x zoom ratio lets you move from wide-angle scenes to telephoto portraits without swapping glass. VC image stabilisation and an RXD autofocus motor keep handheld shooting steady and quiet.

Replaces multiple primes and slower zooms

This single lens covers focal lengths that would otherwise require several prime lenses or a variable-aperture zoom. The jump is worth it when you need f/2.8 brightness across the entire range for low-light work or consistent depth-of-field control. Close focus at 0.19 m wide and 0.39 m tele adds macro-style detail without extra accessories. The bundled DG-NEX extension tubes extend magnification further for extreme close-ups.

Steady output during extended sessions

VC stabilisation maintains sharpness during long handheld sequences such as event coverage or video runs. The RXD stepping motor drives focus smoothly without hunting, keeping noise off audio tracks. Constant f/2.8 exposure simplifies metering when light changes across a shoot. Weather-resistant construction and a fluorine-coated front element protect the optics during prolonged outdoor use.
