# Title: Sony FE 100-400mm f/4.5 GM OSS Lens ## Description: G Master Optical Performance Sony's G Master designation is reserved for its highest performing optics, offering exceptional sharpness, smooth bokeh, speed, and overall performance. This 100-400mm f/4.5 is designed as a versatile replacement for multiple telephoto primes. Constant f/4.5 maximum aperture provides better long-end performance compared to the previous f/4.5-5.6 design while remaining portable and handholdable. Bright design supports ambient shooting and improves depth of field control and subject separation. ED XA, XA, Super ED, and ED elements deliver high sharpness and smooth rendering, even with backlit or complex backgrounds. Nano AR Coating II reduces flare and enhances contrast and color. Floating focus design ensures consistent sharpness from infinity to the 2.1' minimum focus distance. Rounded 11-blade diaphragm produces smooth, circular bokeh. High-Speed AF, Reliable OSS Designed for speed, precision, and reliability, the autofocus and stabilization systems are ideal for wildlife, sports, journalism, and video applications. Four XD linear motors enable fast, quiet, and precise autofocus, supporting up to 120 fps shooting and 240 fps video. AF is approximately 3x faster than the previous model, with 50% better tracking performance. Internal focusing improves speed and maintains lens length. Internal zoom keeps a consistent center of gravity, ideal for tripod and gimbal use. Reduced focus breathing and support for Breathing Compensation in compatible cameras. 0.25x magnification and 2.1–4.9' minimum focus distance enable near-macro shooting. Manual aperture ring can be de-clicked or locked for flexible control. Balanced 4 lb design improves handheld usability. Optical SteadyShot includes multiple modes for standard, panning, and moving subjects. Intuitive Operability and Design Despite its super-telephoto range and constant aperture, the lens remains portable and suitable for handheld, monopod, or tripod use. Measures 12.9" and weighs approximately 4 lb, adding internal zoom and a constant aperture compared to its predecessor. Supports 40.5mm rear drop-in filters and 95mm front filters. Four focus hold buttons and a focus mode switch for quick control. Customizable function ring for camera and exposure settings. Dust- and moisture-resistant construction with sealed seams. Hybrid metal and plastic construction balances durability and weight. Fluorine-coated front element resists water, oil, and dirt. Removable tripod collar with click stops for orientation changes. Lens hood includes locking button and filter window. Teleconverter Compatibility Compatible with Sony FE 1.4x and 2.0x teleconverters while maintaining autofocus and auto-exposure.
