Sony FE 100-400mm f/4.5 GM OSS Lens

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.
