Ultra-wide zoom for Sony E-mount

The Tamron 17-28mm f/2.8 Di III RXD is a large-aperture ultra-wide zoom built for Sony full-frame mirrorless cameras. It covers a 17-28mm focal range with a constant f/2.8 aperture throughout. Weighing 14.8 oz and measuring 3.9 in long, it balances well on compact bodies. The RXD stepping motor provides quiet autofocus suitable for both stills and video work.

Verify mount and filter size before ordering

Confirm your camera uses the Sony E-mount for full-frame coverage; APS-C models will give a narrower field of view. The lens accepts 67mm front filters, which is unusually small for this class of ultra-wide zoom. There is no built-in image stabilisation, so steady handheld technique or in-body stabilisation is required. Minimum focus distance is 7.5 in at the wide end for close-up compositions.

Pair with standard zoom for full coverage

This lens pairs directly with the 28-75mm f/2.8 Di III RXD to create a two-lens kit spanning ultra-wide to short telephoto. Moisture-resistant construction and a fluorine coating on the front element help protect the glass in damp conditions. The compact form factor leaves room in smaller bags for additional accessories. Buyers who need longer reach or a wider maximum aperture than f/2.8 will need separate optics.

Questions about this item

Does the box include a filter or hood, or must they be bought separately?

The lens has a 67 mm filter thread so any 67 mm filter screws on directly. A petal-type hood is supplied in the box.

How do I decide between the 17-28 mm F2.8 and the 28-75 mm F2.8 for Sony E-mount?

The 17-28 mm covers ultra-wide angles from 17 mm to 28 mm; the 28-75 mm starts at 28 mm and reaches 75 mm. Choose the first for architecture and interiors, the second for general-purpose and portraits.

What does the constant F2.8 aperture mean when shooting at 17 mm versus 28 mm on a full-frame Sony body?

At both 17 mm and 28 mm the maximum aperture stays F2.8, so exposure settings do not shift while zooming and depth-of-field control remains consistent across the range.
