Tamron goes wide (and gets a new look, too)

Tamron is introducing a fast, ultra-wide zoom lens for full-frame cameras: the 12-20mm F2.8. It’s being released for Nikon Z-mount and Sony E-mount, and is also ushering in a new look for the company’s lenses.

The 12-20mm F2.8 uses an optical formula with 17 elements in 12 groups, with one expanded glass molded aspherical element, three glass molded aspherical lenses, one extra low dispersion element, and three low dispersion elements. The company says it’s designed to be sharp to the corners, and to minimize and correct for aberrations like color fringing and sagittal coma flare. The latter is especially important for astrophotographers, who may be interested in this lens thanks to its wide focal range.

At 12mm, it can focus on subjects as close as 0.18m (7″), and at 20mm, its minimum focusing distance is 0.28m (11″). It has a 12-blade aperture. Because of its bulbous front element, it can’t accept front filters, but it has a rear filter holder in addition to its integrated lens hood.

Focusing is handled by a linear motor and is internal. While zooming doesn’t make the lens any longer, the front element does physically move back into the body. The lens has both an MF/AF switch and a manual focus lock switch; the latter is again something that will be appreciated by astrophotographers.

Beyond those switches, the lens is covered in controls. There’s a customizable function button in both portrait and landscape orientations, a zoom lock switch that can be used to keep the lens at either 12mm or 20mm, a lock for the aperture ring (or control ring on Nikon), a switch to click or declick that ring and a custom setting switch, which you can use Tamron’s Link software to configure to switch between focus position, change your rings’ rotation direction, limit focus, etc. There’s also a USB-C port you can use to update the lens’s firmware, or to connect it to your phone via a cable or wireless adapter to use Tamron Link.

In its briefing, Tamron took a lot of pride in the lens’s size and weight, saying it was comparable to slower lenses, or ones with less range, and substantially lighter than other options. The E-mount version of the lens weighs 570g (20.1oz), with the one for Nikon weighing 15g more. The Sony version is 119mm (4.7″) long, with the Z-mount version adding 2mm.

This isn’t just a new lens for Tamron, though. The company is also introducing its new branding alongside it. Those familiar with the company’s naming conventions may have noticed what’s not there, first: there’s no “Di III” or “VXD” at the end of the name, denoting it as a mirrorless lens that uses a linear motor. Like Sigma , the company has decided that it doesn’t need to distinguish its DSLR lenses from its mirrorless ones directly in the name, and likewise, most of its lenses going forward are likely to use linear motors.

The updated industrial design language that Tamron is launching with the lens is called “Toned Profile Next,” which the company says is made to match how modern cameras are designed, while feeling better in the hand and more recognizably Tamron. Compared to its older lenses, the 12-20mm F2.8 has chunkier rings for zooming, aperture control and focusing, updated textures for its touchpoints, and new placement and print color for its branding. It also narrowed the champagne-colored “brand ring” that borders the lens mount.

I personally quite like the new look, especially since it comes with a clicking aperture ring on E-mount, something Tamron hasn’t been including on its recent lenses. I also appreciate that it’s now quite easy to grip the control rings and to distinguish which one your finger is on just by feel. The switches and buttons are all satisfying to use, and the lens feels solidly built, even if I don’t prefer the finish’s smooth texture.

The Tamron 12-20mm F2.8 will cost $1699 for the E-mount version and $1799 for the Z-mount version; the company says the difference comes down to volume, behind-the-scenes differences in manufacturing, and the competition on the different mounts. The Sony version will be available starting July 30th, while Nikon owners will have to wait until August 27.

Thanks to Nikon for the loan of a Z8 to shoot this gallery. All images were processed using our standard lens workflow in Capture One, with the manufacturer’s distortion correction applied but no correction of vignetting. The profile corrects a minor amount of distortion – barrel at the wide end and pincushion at the long end – but we wouldn’t consider it an essential part of the lens design.
