Sony FE 400mm F4.5 GM OSS Lens (Sony E)

OVERVIEW

A lightweight, compact 400 mm prime

This high-performance 400 mm F4.5 super-telephoto prime lens weighs just 994 g (35.1 oz.) despite offering innovative G MasterTM optics and extraordinary image quality. Balance is excellent too, affording smooth, easy handling and minimum fatigue when shooting handheld. Overall length is just 242 mm (9-1/2 in.) for outstanding mobility.

G MasterTM sharpness for breathtaking detail

Super ED (Extra-low Dispersion) and ED glass elements in an advanced G Master optical design minimize aberration for stunning resolution, while Sony’s Nano AR Coating II suppresses flare and ghosting for superior clarity and contrast, even in backlit conditions that are often encountered when shooting wildlife and other outdoor subjects.

Individually optimized for exquisite bokeh

In addition to featuring an innovative new optical design, the spherical aberration of each lens is individually calibrated to deliver optimum bokeh quality. An 11-blade circular aperture contributes to smooth, beautiful ball bokeh. Gorgeous G MasterTM bokeh can really make subjects stand out, especially at a super-telephoto focal length.

Fast, precise AF captures the moment

Two of Sony's advanced XD (extreme dynamic) Linear Motors and a refined algorithm bring out the full AF potential of the latest camera bodies. Focus and subject tracking are fast, precise, and quiet. Unpredictable subject movement is reliably tracked and captured, even when shooting 120 fps bursts with the α9 III body.

A great choice for movies

Innovative lens technology ensures that focus breathing is effectively suppressed for smooth, professional-looking movies. The XD Linear Motor drive system and circular aperture unit are quiet too, so movie audio won’t be spoiled by lens noise or vibration. Linear Response MF supports direct, intuitive manual focus control when needed.

800 mm with optional teleconverter

An optional teleconverter can be used to extend focal length up to 800 mm for even greater reach when you want to capture distant wildlife or other subjects.

Enhanced shooting freedom and control

Optical image stabilization with selectable modes delivers stable framing and sharp images when shooting handheld. The lens and a compatible body can work in concert for even more effective stabilization.

Customizable for any shooting style

Four focus hold buttons allow easy access in any orientation. A function ring can be assigned to control APS-C/Full Frame switching, Preset Focus, or Power Focus. A dedicated switch is also provided for optical stabilization ON/OFF switching and mode selection.

Quick, easy focus adjustment

If focus locks onto the wrong subject, it can be returned to the intended subject simply by rotating the focus ring when the Full-time DMF switch is ON. A Focus Range Limit switch allows the lens’s focus range to be limited for faster focusing. This type of detailed control significantly enhances overall focus flexibility.

Reliable in challenging outdoor conditions

A dust and moisture resistant design ensures high reliability in outdoor conditions where light rain and airborne dust might otherwise be a problem. The front lens element features a fluorine coating that prevents contaminants from sticking to the lens surface while making it easier to clean.
