The Sony FE 28-70mm f/2 GM is a high-performance all-around zoom lens that offers a faster f/2 aperture compared to conventional f/2.8 options. As Sony’s first GM zoom with a constant f/2 maximum aperture, it provides a versatile wide-angle to portrait-length range, making it an ideal choice for photographers and filmmakers looking to replace multiple primes without sacrificing speed. Covering some of the most frequently used focal lengths, this lens delivers impressively fast autofocus, exceptional image quality, and a well-balanced design for both photography and filmmaking applications.
G Master Performance
The Sony FE 28-70mm f/2 GM embodies Sony’s highest-performing G Master optics, delivering exceptional sharpness, smooth bokeh, and rapid autofocus. Designed as a single-lens replacement for multiple primes, it offers unparalleled versatility.
- The constant f/2 maximum aperture is a full stop faster than f/2.8, excelling in low-light conditions and providing superior depth of field control for stunning subject-background separation.
- XA, Super ED, aspherical, and ED elements ensure high resolution and smooth rendering, making it an ideal choice for a range of subjects, from architecture and landscapes to portraiture and weddings.
Advanced Optical Design
The Sony FE 28-70mm f/2 GM features cutting-edge optical coatings and design elements to deliver superior image quality in diverse shooting conditions.
- Nano AR Coating II effectively suppresses flare and ghosting, ensuring rich contrast and vibrant colors, even in challenging lighting.
- A floating focus design maintains consistent sharpness throughout the entire focusing range, from infinity to the 1.2′ minimum focusing distance.
- The rounded 11-blade diaphragm produces smooth, circular bokeh, enhancing subject isolation with a natural, artistic background blur.
Designed for Hybrid Shooters
The 28-70mm f/2 GM is built for both photographers and filmmakers, incorporating features that enhance its versatility:
- Four XD (Extreme Dynamic) linear motors provide fast, quiet, and smooth autofocus, supporting continuous shooting up to 120 fps and high-speed video recording up to 240 fps.
- An internal focusing design ensures rapid focusing performance while maintaining the lens’s overall length.
- The short-throw zoom design extends just 0.7″ when transitioning between 28mm and 70mm, reducing the need for gimbal adjustments when changing focal lengths.
Focus breathing is minimized optically, and the lens supports Breathing Compensation in select cameras to prevent angle of view shifts while zooming. The manual aperture ring can be de-clicked for silent adjustments, and the zoom smoothness can be set to either smooth or tight for precise handling. Weighing 2 lb, the lens is designed with a rear-weighted balance to enhance comfort during handheld use.
Portable and Nimble Design
Despite its large maximum aperture and versatile range, the 28-70mm f/2 remains portable and relatively lightweight for handheld shooting and daily use. Measuring 5.5″ long and weighing 2 lb, it is 28% larger and 24% heavier than the 24-70mm f/2.8 GM II while offering twice the brightness. The manual aperture ring provides tactile exposure control, can be de-clicked for silent iris pulls, or locked in the ‘A’ position for camera-based aperture adjustments. Two programmable focus hold buttons and a focus mode switch offer intuitive focus control, while a zoom smoothness switch allows for Smooth or Tight torque settings. Its hybrid construction balances durability with a lightweight design, featuring dust- and moisture-resistant sealing, a fluorine-coated front element for easy cleaning, and an included locking lens hood with a filter window for quick adjustments of rotating filters.
