Why This Lens
The 28-75mm f/2.8 has become the standard zoom of choice for many Sony shooters, offering a more compact and affordable alternative to Sony’s own 24-70mm f/2.8 GM while maintaining excellent image quality and autofocus performance.
f/2.8 Constant Aperture
The constant f/2.8 aperture provides consistent exposure throughout the zoom range, enabling:
Low-light performance: Shoot indoors and at night without flash
Subject isolation: Smooth bokeh that separates subjects from backgrounds
Fast shutter speeds: Freeze action in challenging light
VXD Linear Autofocus Motor
The VXD (Voice-coil eXtreme-torque Drive) linear motor delivers fast, quiet, and precise autofocus — suitable for both stills and video. It’s significantly faster and quieter than the original G1 version’s motor, with improved tracking for moving subjects.
Improved Optical Design
The G2 features an updated optical formula with specialized elements (XLD, LD, GM, and aspherical) to control chromatic aberration, distortion, and spherical aberrations. The result is sharper images with better color rendition and reduced fringing compared to the original.
Compact and Lightweight
At just 540g, this lens is remarkably light for an f/2.8 standard zoom. It pairs perfectly with Sony A7C, A7C II, A7 IV, and A7R V bodies for a portable full-frame kit.
67mm Filter Thread
The common 67mm filter thread matches many other Tamron lenses and Sony primes, allowing you to share filters (ND, polarizers, etc.) across your lens collection.
Close-Focus Capability
The minimum focus distance of 0.18m at 28mm allows for dramatic wide-angle close-ups with a maximum magnification of 1:2.7 (0.37x), approaching macro capability.
Honest Note
The Tamron 28-75mm G2 is widely praised as one of the best value lenses for Sony E-mount. Owner reviews note it’s “insane value” with “fast, sharp, lightweight” performance . Autofocus is good in good lighting but may struggle slightly in low-light conditions — tapping the screen to focus helps .
What you get: f/2.8 constant aperture, excellent value, lightweight, fast VXD autofocus, and G2 improvements over the original. What to consider: 28mm vs 24mm wide end (the difference between 28mm and 24mm is significant for some users), plastic build (but high-quality), no optical stabilization (relies on camera IBIS).
