Sony E 10-20mm f/4 G PZ Autofocus APS-C Lens for E-Mount, Black {62} SELP1020G

Sony's 178g power zoom ultra-wide built for APS-C video work.

At 55mm long and 178g, the 10-20mm f/4 G PZ is the smallest and lightest ultra-wide constant-aperture power zoom built for APS-C. That's not a spec to gloss over. Internal zoom and focus mean the barrel never extends, so balance stays fixed whether the lens is on a gimbal, a matte box rig, or just handheld. The constant f/4 aperture across the full 10-20mm range (equivalent to 15-30mm on full-frame) means exposure stays locked when you're doing a slow power zoom pull during a take.

The optical formula runs 11 elements in 8 groups, including two ED elements, an ED aspherical element, and two additional aspherical elements, that's a serious commitment to controlling the chromatic aberration and field curvature that plague lesser wide-angle designs. The power zoom lever gives you continuously variable speed control, which is the feature that separates this lens from manual-zoom alternatives for video: you can execute a glacially slow, perfectly smooth zoom that no human hand can replicate by twisting a ring. Focus breathing is minimized by design, and compatible Sony bodies can apply breathing compensation on top of that. Two linear AF motors handle fast-moving subjects for stills and track cleanly through high-frame-rate video. Minimum focus distance sits at 5.1 inches in manual focus mode, giving you real close-up reach for a wide-angle zoom.

Who It's For

Solo video creators and vloggers get the most direct benefit from the power zoom lever and the constant barrel length, no shadow changes mid-shot, no balance shift on a gimbal when you zoom. Run-and-gun documentary shooters working APS-C Sony bodies will appreciate the dust and moisture resistant construction alongside the 109° angle of view at 10mm. Travel photographers shooting stills who also produce video will find the 178g weight genuinely useful when packing light. Gimbal operators and small-crew cinematographers using Super35 or APS-C cameras who need smooth, remotely controllable zoom pulls without adding a follow focus system will find few alternatives at this size.

FAQ

What's the actual close-focus range on this lens?

Autofocus minimum is 7.9 inches with 0.14x magnification; manual focus goes to 5.1 inches at 0.18x magnification, giving you real close-up capability for a wide-angle zoom.

Does the barrel extend when you focus or zoom?

No. Internal zoom and focus mean the lens stays 55mm long regardless of focal length or focus distance, keeping balance fixed on gimbals and rigs.

How slow can you make the power zoom?

The variable-speed lever gives continuously adjustable zoom speed, allowing glacially slow pulls that manual zoom rings can't match for video work.

Does focus breathing get in the way during video?

The lens is engineered to minimize breathing by design, and compatible Sony bodies can apply additional breathing compensation on top of that.

Can I control zoom remotely?

Yes. You can operate zoom via assignable buttons on compatible cameras, accessory grips, or remote commanders without touching the lens itself.

What's the equivalent focal length on full-frame?

15-30mm equivalent on full-frame, giving you a 109° to 70° angle of view.

Is this sealed against dust and moisture?

Silicon seals around buttons and switches plus a rubber gasket at the mount reduce dust and moisture incursion for outdoor reliability.
