Redefining Super-Telephoto Portability

Offering super-telephoto reach in an ultra-light package, the Sony FE 400mm f/4.5 GM OSS Lens packages G Master optical precision into one of the most portable 400mm primes ever made. With high-speed autofocus support, advanced internal stabilization, and a weather-resistant design, this lens is optimized for handheld use everywhere from football sidelines to photographing wildlife deep in the woods.

Optimized for Handheld UseAvoiding the traditional size and weight difficulties associated with super-telephoto setups, this 400mm f/4.5 is easy to bring with you for a day of handheld shooting, ensuring you'll have the reach you need in any situation.A maximum aperture of f/4.5 allows the lens to be shorter and lighter without significantly compromising light-gathering abilities when paired with the OSS.

Thanks to the use of a single front element, the center of gravity of the lens is shifted toward the camera body for a well-balanced design perfect for handheld use.
With a length of only 9.5" and weighing 2.2 lb, this lens looks closer to a 70-200 f/2.8 than a super-telephoto prime. Compared to the FE 400mm f/2.8, this f/4.5 version weighs 4.2 lb less and measures 4.6" shorter in length.
