The Sony FE 24-70mm f/2.8 GM II is Sony’s latest flagship standard zoom lens, promising lighter weight, improved autofocus, and sharper images than its predecessor. If you’re a professional or serious enthusiast shooting with Sony’s full-frame mirrorless cameras, this lens could be the missing piece in your kit. But is it really worth upgrading to, or is the original GM still the better choice? In this review, I’ve put the new GM II through real-world tests—from low-light portraits to fast-action sports—to see if it lives up to the hype. Whether you shoot stills, video, or both, this lens aims to deliver pro-level performance without compromise. The GM II feels noticeably lighter than the original GM, weighing just over 800g, which is impressive for a constant f/2.8 zoom. Sony has used a magnesium alloy shell with weather sealing, giving it a premium, rugged feel that matches their high-end bodies. The zoom and focus rings are buttery smooth, with just the right amount of resistance—no play or wobble here. The fluorine-coated front element resists smudges and dust, a small but welcome detail. The lens balances well on Sony’s A7 IV and A7R V, though it’s still a hefty setup to carry all day. The manual zoom ring is precise, making it a joy to use for video work where smooth transitions matter. Autofocus is where the GM II truly shines. Sony claims a 2x improvement in tracking speed, and it shows—subjects lock on instantly, even in challenging lighting. Sharpness is exceptional across the entire zoom range, with minimal softness at the edges even when wide open. The f/2.8 aperture delivers creamy bokeh, though it’s not as buttery as some prime lenses. Compared to the Tamron 28-75mm f/2.8 Di III RXD, the GM II is sharper and faster, but also pricier. Against the original GM, the improvements are subtle but meaningful—better AF, lighter weight, and slightly better flare resistance. For video shooters, the quiet focus motor and minimal breathing make it a top-tier choice. In real-world use, the GM II excels in low light, where the f/2.8 aperture and improved coatings keep images clean and detailed. Landscape shooters will appreciate the consistent sharpness from 24-70mm, while portrait photographers will love the smooth background separation. The lens handles flares well, though strong backlighting can still cause issues. Battery life isn’t a concern here—this is a lens, not a camera—but the weight savings make it easier to carry on long shoots. If you’re shooting events, weddings, or travel, the GM II is a versatile workhorse that won’t let you down. Is the Sony FE 24-70mm f/2.8 GM II worth the upgrade? If you’re coming from the original GM or a third-party alternative, the improvements in autofocus and weight are compelling enough to justify the cost. For new buyers, it’s one of the best standard zooms available, especially if you prioritize sharpness and reliability. Just be prepared to invest in a sturdy bag—this lens is a beast. If you shoot Sony full-frame and need a do-it-all lens, the GM II is hard to beat.
