Sony Korea is releasing in Korea the super-telephoto zoom lens "FE 100-400mm F5.6–8 OSS (SEL100400)," which supports a 100–400mm focal length while reducing the weight to 654g.
Sony Korea said on the 11th it will officially release the SEL100400 super-telephoto zoom lens for Sony E-mount full-frame cameras. The price is 1,299,000 won.
The SEL100400 supports a 100–400mm focal length on the 35mm full-frame format. It measures 78.2×164.5mm and weighs 654g. It focuses on improving portability and handheld shooting convenience for super-telephoto shooting.
The lens is constructed with 15 elements in 10 groups. Two Super ED (extra-low dispersion) elements and two aspherical elements are arranged to suppress chromatic aberration and various distortions. The maximum aperture is F5.6–8, and a 9-blade circular aperture is applied to produce background blur.
The minimum focusing distance is 0.86m at the 400mm telephoto end and 1.13m at the 100mm wide end. The maximum magnification is 0.41x, allowing users to magnify and shoot not only distant subjects but also close subjects such as flowers and insects.
By attaching separately sold 1.4x or 2x teleconverters, the focal length can be extended to up to 800mm. When used together with APS-C mode, it can shoot with an effective angle of view equivalent to up to 1200mm.
Dual linear motors are applied to autofocus (AF). It is designed to track fast-moving subjects such as birds, sports, trains, and aircraft. When used with Sony "Alpha 9 III (α9 III)," it also supports up to 120 continuous shots per second while maintaining AF.
It also features optical image stabilization (OSS). It reduces image shake that can occur due to hand movement in the super-telephoto range and can be linked with the in-body image stabilization of compatible Sony cameras.
It supports a breathing compensation function for video. This method corrects "focus breathing," in which the angle of view slightly changes when shifting focus, in the camera body.
User-assignable focus-hold buttons, focus mode and focus range switches, and a zoom lock switch are also applied. It features dust- and moisture-resistant design, and the included lens hood helps reduce flare and ghosting.
A Sony Korea official said, "The SEL100400 is a product that enhances portability by reducing size and weight while maintaining super-telephoto zoom performance," adding, "It can be widely used by users starting super-telephoto shooting or those who shoot photos as a hobby."
