Tamron finally brings its smallest fast zoom to Nikon Z
Tamron has officially launched its 20-40mm f/2.8 Di III VXD, model A062, for Nikon Z mount full-frame mirrorless cameras. Per Tamron's October 8 global newsroom announcement, the lens ships October 22, 2026 at a US price of $729, the same product Tamron first introduced for Sony E in late 2022 (the E-mount version is $699, so Z-mount carries a $30 premium). It is the first 20-40mm f/2.8 for full-frame Z mount, and it arrives without OIS in the lens itself.
In Tamron's own words, the lens is "class-leading" in compactness among fast-aperture F2.8 standard zooms for full-frame mirrorless as of August 2026 — the asterisk in their own disclaimer. That's a fair distinction: at 380g (13.4oz) and 88.7mm long, it undercuts Tamron's earlier 28-75mm f/2.8 G2 by a noticeable margin and is meaningfully smaller than Sony's 16-35mm f/2.8 GM II in the same conversation.
What the spec sheet actually delivers
The optical construction is 12 elements in 11 groups, with Tamron's VXD (Voice-coil eXtreme-torque Drive) linear motor handling autofocus. The VXD motor, which Tamron says is shared with the 50-400mm and other recent redesigns, drives an extending front element on focus. Aperture control is electronic only, with no aperture ring.
For working distances, Tamron advertises a minimum object distance (MOD) of 0.17m at the 20mm wide end. That's where the 1:3.8 maximum magnification ratio lives, which is closer to a "wide macro" claim than a true half-macro figure. Stop down to 40mm and the MOD extends to 0.29m with a maximum magnification of 1:5.1. Real close-up users will probably still reach for a dedicated macro lens, but for documentary-style shots at 20mm with the subject a few inches from the front element, this is more useful than the typical standard zoom offers.
Weather sealing includes Tamron's moisture-resistant construction and a fluorine coating on the front element, with the lens rated for use down to -10°C. The filter size remains the family-friendly 67mm that runs across Tamron's recent E and Z lenses.
Image quality and autofocus behavior I can't verify here
I haven't handled the Nikon Z A062, and I haven't shot with the E-mount version either, so anything I'd say about rendering, autofocus speed in real-world conditions, or flare resistance on the Z body would be guessing. PetaPixel's coverage of the E-mount A062 in 2023 and DPReview's tracking since then talk about "excellent edge sharpness" at f/4 and "some flare susceptibility" wide open, and Tamron's own promo material leans on the same data, but those are third-party and manufacturer claims respectively, not my own take.
What I do notice in the spec sheet: the 67mm filter, the linear motor, and the 380g weight form a coherent trifecta. If you already own a Tamron 28-75mm f/2.8 G2 or the 70-180mm f/2.8 on Z, you'll have spare 67mm caps and spares in your bag. If you don't, you'll need a 67mm CPL or ND set on top of the lens. That's an awkward filter cost for first-time buyers, even at the $729 price.
Where the A062 actually fits in a Z kit
The 20-40mm f/2.8 sits in a strange gap. Nikon's own Z 24-70mm f/2.8 S is the obvious "real workhorse" choice and weighs twice as much. Nikon's Z 24-120mm f/4 S is the obvious "everyday travel zoom" but it's an f/4 lens. Tamron's argument, and it's a defensible one, is that for vloggers, landscape shooters, and event shooters who want a constant f/2.8 across the wide end at a sub-400g weight and under $1,000, there really wasn't a native Z option. The Z 14-30mm f/4 S covers a wider range but stops down; the Z 26mm f/2.8 pancake is compact but isn't a fast constant-aperture zoom.
For hybrid shooters moving between stills and 4K video with a Z 6III, Z f, or Z 8, the 20-40mm + a 70-200mm f/2.8 (Nikon's Z 70-200mm f/2.8 VR S II or Sigma's 70-200mm f/2.8 DG DN OS Sport) covers the gap between ultrawide and short telephoto without breaking the bank. The combination of those two lenses plus the Z body is still lighter than the Z 24-70mm f/2.8 S paired with a Z camera.
Pricing and availability in real numbers
US: $729. Canada: $999 CAD. UK: £429. EU: €499. Japan: ¥119,900 tax-included (¥84,700 typical retail prices are not always matched by Nikon-mount releases per PRONEWS). Black is widely available; the silver version, per Pro Moviemaker and Tamron's EU newsroom, remains a Panasonic Direct exclusive. The Z-mount version is the third major Tamron release for Z, following the 70-300mm f/4.5-6.3 in 2024 and the 90mm f/2.8 macro in 2025.
I'll hold judgment on rendering and autofocus behavior until I get a review unit on a Z body. The spec sheet and the weight class, though, are exactly what a Z shooter who's been eyeing this lens would want.
