Tamron 28-75mm f/2.8 Di III VXD G2 Full-Frame Lens for Sony E-Mount, Black {67} A063

Tamron's 28-75mm f/2.8 G2 redefines what a budget fast zoom can do

The second-generation VXD autofocus system is the headline upgrade here. Tamron's Voice-coil eXtreme-torque Drive locks focus roughly twice as fast as the original RXD version, and it does so quietly enough for video work. Sharpness at 75mm f/2.8 holds from center to corners with only the faintest softness at the extreme edges. At 50mm, center performance is flat-out strong. Wide open at 28mm, corners lag behind, but stopping to f/8 brings them into line, a reasonable ask for architecture or landscape work.

The physical specs matter here. At 539 grams and 116.8mm long, this lens sits noticeably lighter on an A7-series body than the Sony FE 24-70mm f/2.8 GM, which runs 886 grams. The 67mm filter thread keeps accessory costs down too. A minimum focus distance of 18cm at 28mm gives a 1:2.7 maximum magnification, so detail work on small subjects is possible without swapping to a dedicated macro lens.

Chromatic aberration is well-managed for a zoom at this price point, and distortion correction profiles in Sony bodies handle the mustache distortion at 28mm without much fuss. For Sony Alpha shooters who need a constant f/2.8 zoom and don't want to spend twice the money on the GM alternative, this lens earns its place in a serious kit.

Who It's For

Travel photographers working from Sony A7-series bodies will appreciate the 539-gram weight and weather-resistant build on long shooting days. Wedding and event photographers get consistent f/2.8 exposure across a 18mm-to-75mm working range with AF fast enough for receptions and candid moments. Portrait shooters working at the 75mm end benefit from the strong wide-open sharpness in that focal range. Videographers running Sony mirrorless rigs get the quiet VXD drive without the bulk or cost of the GM glass.

FAQ

How does the VXD autofocus compare to the original RXD version?

The new VXD system focuses roughly twice as fast as the previous RXD generation while staying quiet enough for video recording. Speed and silence matter equally here - you get both.

Is corner sharpness acceptable at 28mm f/2.8?

Corners soften noticeably at wide open, but stopping to f/8 brings them into line. At 50mm and 75mm, corner performance is strong from f/2.8 onward.

How does weight and size compare to the Sony FE 24-70mm f/2.8 GM?

This Tamron runs 539 grams versus the Sony's 886 grams, and measures 116.8mm long versus the Sony's 136mm. You're looking at roughly 40% lighter and noticeably more compact.

Can this lens handle close-up work without a macro lens?

The 18cm minimum focus distance at 28mm with 1:2.7 magnification covers detail work on small subjects. It won't replace a true macro lens, but it's capable for many close-up situations.

How bad is the distortion at 28mm?

Mustache distortion (lines curving inward near center, outward at edges) is noticeable on architecture, but Sony's lens correction profiles handle it without much fuss. At longer focal lengths, the distortion shifts to more subtle pincushion patterns.

Is chromatic aberration visible?

Minimal fringing appears in challenging situations at wide apertures - slight magenta in foreground, green at edges - but it's well-managed for a zoom at this price point. Stopping down reduces it further.

What's the filter thread size?

67mm, which keeps accessory costs down compared to lenses using 77mm or 82mm threads.
