Professional Telephoto Reach – The Sony 100–400 mm GM lens delivers outstanding range for sports, wildlife, and action photography. On full-frame bodies, it covers a versatile super-telephoto span, while on APS-C cameras it offers an equivalent 150–600 mm reach. Despite its power, the lens remains lightweight and balanced, making it easier to handhold or pair with monopods and gimbals during long shooting sessions. Exceptional G Master Image Quality – As part of Sony’s flagship G Master line, this lens integrates two Extra-Low Dispersion (ED) and one Super ED element to minimize chromatic aberration, while a Nano AR Coating reduces flare and ghosting. The result is ultra-sharp images with vivid contrast and beautifully smooth background bokeh—hallmarks of G Master performance.

Ideal for both still photography and video, the system locks onto fast-moving subjects like birds in flight or athletes in motion, while internal focusing keeps operation smooth and responsive. Durable, Weather-Sealed Construction – Built to withstand demanding field use, the 100–400 mm GM lens features dust- and moisture-resistant sealing plus a fluorine-coated front element to resist fingerprints and debris. Zoom torque adjustment allows users to control resistance from smooth to tight, while customizable focus hold buttons enhance workflow for professional shooters in the field.
