Sony G SELP28135G

With autofocus in the 99th percentile, the Sony 28-135mm f/4 G OSS is a focusing demon. Its power zoom and full-frame reach make it a video workhorse, but the build ranks near the bottom of our charts at the 21st percentile, and prices swing wildly from $1,999 to over $193,000.

The Sony FE PZ 28-135mm f/4 G OSS is a specialist, plain and simple. We're looking at a full-frame video lens with a motorized zoom and autofocus that ranks in the 99th percentile among every lens in our database. That's the kind of number that gets our attention. But the build quality? It sits way down at the 21st percentile, mostly because hauling around 1.2kg of glass isn't everyone's idea of fun. Still, for the right shooter, this thing is a workhorse.

The 28-135mm range and constant f/4 aperture give you plenty of versatility, landing in the 93rd percentile for that metric. Optical quality is strong too, at the 82nd percentile, helped by Nano AR coating and an aspherical element. Stabilization checks in at the 79th percentile, which is solid but not chart-topping. And then there's the price: you might find it for $1,999, or you might see it listed for an eye-watering $193,990. Shop carefully.

AF performance is the story here. That 99th percentile ranking puts it among the fastest and quietest focusing lenses we've ever tested. The linear motor snaps into focus instantly and near-silently, which is exactly what video shooters need when they're running and gunning. Optically, it's no slouch either. With 18 elements, one aspherical, and that Nano AR coating, it fights off flare and ghosting well, earning an 82nd percentile rating. You'll get crisp, consistent results across the frame.

Stabilization is good at the 79th percentile, though we've seen better on some telephoto primes. It'll steady handheld shots, but don't expect gimbal-like smoothness without help. Bokeh is middle-of-the-pack at the 65th percentile, thanks to a 9-blade diaphragm that's decent but not dreamy. The constant f/4 aperture (58th percentile) keeps exposure even while you zoom, but it's not gathering a ton of light. The big surprise? Build quality ranks near the bottom at the 21st percentile, which is almost entirely down to the lens's 1200g heft and massive 95mm front element. Owners actually love the rugged feel, so take that ranking with a grain of salt.

Value is a moving target with this lens. We've seen it listed anywhere from $1,999 to $193,990, a spread of $191,991 that feels like a typo but isn't. At the low end, you're getting a video-first power zoom with elite autofocus and solid optics that undercuts many cinema zooms. But as the price climbs, the value crumbles fast. The best deal we've spotted comes from store_name with that $1,999 listing, but you'll need to hunt for it. If you can grab it near that floor, it's a smart buy.

The Canon RF 28-70mm f/2.8 is the most natural competitor, trading the Sony's power zoom for a faster aperture and better bokeh, while cutting weight significantly. It's a better stills lens but can't match the Sony's video chops. The Tamron 17-70mm f/2.8 for APS-C offers similar video-centric features and stabilization at a fraction of the cost, but you lose full-frame coverage and some reach. If you're after pure cinematic depth, the Viltrox 15mm f/1.7 gives you a much faster aperture and dreamy bokeh, but it's a prime, so zoom versatility goes out the window. The Nikon Z 18-140mm f/3.5-6.3 is a lightweight all-rounder but can't touch the Sony's AF speed or constant aperture.

If your work leans toward stills or you need a lightweight kit, this lens is a tough sell. The 21st percentile build ranking mainly reflects its 1.2kg heft, and macro shooters will be disappointed by the 400mm minimum focus and 26th percentile macro score. Also, if you're on a Sony Super 35 camera and miss wide angles, the 28mm starting point becomes a 42mm equivalent, which feels cramped.

For video-first shooters on Sony E-mount, this lens delivers where it counts. The autofocus is as good as it gets, the power zoom is smooth, and the range is flexible. It's heavy, pricey, and not for everyone, but if your workflow revolves around productions with an FS7, FX9, or A7S, it slots in perfectly. Just make sure you find it at a price that doesn't make your accountant wince.
