The Sony FE 24-70mm f/2.8 GM is a professional-grade full-frame E-mount zoom lens designed for the Sony a7-series cameras, and the predecessor to the Sony FE 24-70mm f/2.8 GM II. Key features include:
Covers a wide to short telephoto focal range
Fast, nearly silent autofocus
Rounded nine-blade aperture diaphragm
Great for portrait and event photography
Full-Frame E-mount. As a part of the FE line of lenses, the FE 24-70mm f/2.8 GM is designed to cover the full-frame sensors on Sony a7-series cameras. Since it’s an E-mount lens, it’s also fully compatible with APS-C NEX cameras.
Working Photographer’s Bread and Butter. When used on a full-frame camera, the FE 24-70 GM provides a fast-aperture, wide to short tele focal range that’s perfect for portrait and event photography. Using an APS-C sensor camera? You’ll have a focal length equivalent to 36-105mm. The fast f/2.8 aperture offers shallow depth-of-field capability, as well as allowing you to keep shooting even in low light.
Direct-Drive Super Sonic Wave Motor Autofocus System. This internal-focusing system uses piezoelectric elements oscillating at ultrasonic frequencies to provide fast, highly accurate, and nearly silent autofocus performance that’s great for still and video use.
G-Master Series Quality. The GM series is Sony’s premium lens offering. What sets it apart from other Sony lenses is an emphasis on an extremely high resolving power of fifty lines per mm, out-of-focus “bokeh” quality, and a robust, weather-sealed body.
Advanced Optics. The FE 24-70 GM features three aspherical elements and two extra-low dispersion elements—including one “XA” extreme aspherical element and one Super ED element—for minimizing chromatic aberrations and distortion throughout the zoom range, and for producing clear, high-contrast images. The lens’s rounded nine-blade aperture diaphragm gives images smooth out-of-focus areas when you desire a shallow depth of field.
