The world’s smallest and lightest constant f/4 ultra-wide-angle APS-C power zoom lens offers outstanding mobility and superb image quality for both stills and movies. Smooth, versatile power zoom provides speed and framing control that brings extra expression to dynamic ultra-wide visual perspectives.

Outstanding optics in a compact lens

Three aspherical elements suppress field curvature and astigmatism while an ED (Extra-low Dispersion) aspherical element subdues chromatic aberration for high image-wide resolution throughout the 10 to 20mm zoom range (35mm full-frame equivalent: 15 to 30mm). Natural-looking G Lens bokeh can deliver striking expression with this lens’s 0.2-meter minimum AF distance and 0.13 ~ 0.17-meter minimum MF distance.

Responsive power zoom

A new electronic power zoom system instantly converts zoom ring rotation to actual zoom operation so that the creator’s intent is faithfully captured. There’s also a zoom lever that makes it easy to execute super-slow constant-speed zooms that are difficult with manual zoom. Zoom can also be controlled remotely from the optional GP-VPT2BT grip, RMT-P1BT remote commander, or the Imaging Edge Mobile application.

Extraordinary AF for stills and movies

Two linear motors ensure fast, quiet, low vibration autofocus that can smoothly track subjects when shooting high frame-rate movies and reliably follow fast-moving subjects when shooting stills continuously at high speed. Focus is especially critical when shooting 4K or 8K movies, particularly while zooming. This lens easily acquires focus and tracks challenging subjects smoothly and silently.
