Tamron’s 16-50mm F2.8 is a fast, sub-$550 kit lens replacement for every APS-C system

The compact, unstabilized lens arrives in the lineup alongside the existing 17-70mm F2.8 Di III-A VC RXD and will be available for Canon RF, Fujifilm X, Sony E and Nikon Z mounts. This makes it one of the few instances of a lens Nikon has lisenced that competes directly with one of its own lenses.

Elsewhere, the 16-50mm offers a wider alternative to Sigma’s 18-50mm F2.8 and, while it’s physically longer, it takes the same 55mm diameter filter.

The lens delivers a 24-75mm equivalent range on Sony, Fujifilm and Nikon bodes, or a 26-80mm range on Canon RF bodies, making it a useful fast everyday lens as a kit zoom replacement.

At 80mm (3.2″) long and with a diameter of a little over 64mm (2.5″) maximum diameter, it is around half the volume of the stabilized 17-70mm F2.8 VC. And with a weight of 305g (10.8oz), it’s 42% lighter. It’s only 4% longer than the Sigma 18-50mm in their retracted states and around 5% heavier, despite covering an appreciably wider range.

The new lens features 14 elements in 10 groups, these include one LD low-dispersion element, two molded glass aspherics and two hybrid aspherical lenses. It can focus as close as 15cm (6″) at wide angle, giving 0.22x magnification. Its 7 aperture blade design is the main area you can see costs being cut, vs the 9 blades on the more expensive 17-70mm.

Sadly, we’ve not had a chance to shoot with the 16-50mm yet, but we hope to in the coming weeks.

The Tamron 16-50mm F2.8 A benefits from the company’s simplified naming system, with “A” indicating that it’s for APS-C and a code number (B091) to distinguish it from any future lenses with similar specs. The Canon, Sony and Nikon versions include a USB-C port, to allow firmware updates. We’re told this is not present on the X-mount version.

The 16-50mm F2.8 will arrive for Sony E-mount and Canon RF users in late October, with Fujifilm X following a month later and Nikon Z hitting the shelves just before the end of the year. It will sell with a list price of $529 for the Sony E and Fujifilm X versions and $549 for Canon and Nikon users. These are at least $170 less expensive than the larger, stabilized 17-70mm F2.8 VC will set you back.

It’s also significantly less than the camera makers’ own-brand 16-50-something F2.8s, which range from $900 for the Nikon 16-50mm F2.8 VR to $1700 for Sony’s 16-55mm F2.8 G.
