A 24–70mm f/2.8 is the lens most working photographers reach for first, and the Sony FE 24-70mm f/2.8 GM II is the sharpest, lightest take on that formula yet. The second-generation G Master standard zoom trims 191g and a big chunk of bulk off its predecessor while improving resolution, autofocus speed, and close-focusing ability. Sony now calls it the world’s smallest and lightest full-frame f/2.8 standard zoom, and on spec alone it’s the benchmark every rival is measured against. Here’s our full review.

What Makes the Sony FE 24-70mm f/2.8 GM II Special

The GM II is a ground-up redesign of Sony’s original 24-70mm G Master. Its headline upgrades:

• Smallest and lightest in class — 695g, roughly 22% lighter and 18% smaller than the original GM.
• 20 elements in 15 groups, including two XA (extreme aspherical), two ED, and two Super ED elements with Nano AR Coating II.
• Four XD Linear Motors driving a floating-focus group for fast, silent autofocus that keeps up with 30fps bursts.
• 11-blade circular aperture for smooth, natural bokeh at every focal length.
• 0.32x maximum magnification with a 21cm close focus at the wide end — genuinely useful for near-macro detail work.
• Dedicated aperture ring with click/de-click and lock, plus two customizable focus-hold buttons.

Image Quality

This is where the GM II justifies its price. The two XA elements keep the lens razor-sharp wide open across most of the frame, with resolution that rivals premium primes. Center sharpness at f/2.8 is outstanding, and corners tighten up nicely by f/4–f/5.6. The Nano AR Coating II suppresses flare and ghosting even shooting into the light, while the 11-blade rounded aperture produces smooth, circular bokeh that stays clean throughout the zoom range.

The close-focus performance is a standout. At 24mm you can focus to just 21cm for a 0.32x reproduction ratio — far better than the typical 24-70mm, and close enough to handle food, product, and detail shots without reaching for a macro lens.

Autofocus & Speed

Four XD (extreme dynamic) Linear Motors split the focusing work and drive a floating focus element, so the lens locks on almost instantly and tracks moving subjects without hunting. Because the motors are near-silent and the lens is rated to keep up with Sony’s fastest bodies, you get full 30fps continuous shooting on the a1 and clean eye-tracking on the a7 IV, a7R V, and a9 III. For event and wedding work, this is the autofocus speed that makes the difference between nailing the moment and missing it.

Video

Sony designed the GM II with hybrid shooters in mind. Focus breathing is dramatically reduced compared to the original, so the frame no longer visibly shifts as you rack focus. The aperture ring can be de-clicked for smooth, silent iris pulls, and linear-response manual focus gives you precise, repeatable focus pulls. Combined with the silent XD motors, it’s one of the best standard zooms you can put on a Sony cinema or Alpha body for video.

Design & Handling

At 695g the GM II sits lightly on a gimbal and balances well on compact bodies like the a7C series. The build is dust- and moisture-resistant, with a fluorine-coated front element that repels water, oil, and fingerprints. The aperture ring clicks in one-third-stop detents, de-clicks for video, and can be locked in “A” to hand control back to the body. An 82mm filter thread matches the rest of the G Master pro zooms, so a single set of filters works across your kit.

Sony 24-70mm GM II vs Original GM vs Sigma 24-70mm DG DN Art

The GM II improves on the original almost everywhere — sharper, faster, lighter, and much better at close focus. Against the Sigma 24-70mm f/2.8 DG DN Art, Sony wins on autofocus speed, resolution, and weight; the Sigma counters with a street price that’s roughly half, making it the value pick if top-tier AF and ultimate sharpness aren’t your priority. If you already own the original GM, the GM II is a worthwhile upgrade; if you’re buying fresh, it’s the class leader.

Verdict

The Sony FE 24-70mm f/2.8 GM II is the best standard zoom Sony has ever made, and arguably the best 24-70mm f/2.8 on the market. It pairs prime-level sharpness and gorgeous bokeh with class-leading autofocus, a featherweight build for its range, and genuine near-macro close focus. The only real drawback is the price — it’s a professional investment. For wedding, event, portrait, travel, and video shooters on the E-mount system, though, it’s the single lens most worth owning.

FAQ

Is the Sony 24-70mm f/2.8 GM II worth upgrading to from the original GM?

For most shooters, yes. The GM II is noticeably lighter (695g vs 886g), sharper across the frame, faster to focus, and dramatically better at close range (0.32x vs 0.24x magnification). If you rely on your 24-70mm daily, the improvements add up quickly.

Does the Sony 24-70mm f/2.8 GM II work on APS-C cameras?

Yes. On APS-C E-mount bodies like the a6700 it behaves like a 36–105mm equivalent, and image quality is excellent. Just note that a lens this size makes the most sense on full-frame bodies.

Is the Sony 24-70mm f/2.8 GM II good for video?

Yes — it’s one of the best standard zooms for video on E-mount. Reduced focus breathing, a de-clickable aperture ring, and near-silent XD Linear Motors make it a strong choice for run-and-gun and gimbal work.
