Sony FE 28-70mm f/2 GM Lens (Sony E)

Sony FE 28-70mm f/2 GM Lens (Sony E)

A Speedier Standard Zoom

The Sony FE 28–70mm f/2 GM is a high-performance all-around zoom that’s faster than conventional f/2.8 options. It’s Sony’s first G Master zoom with a constant f/2 maximum aperture, covering a versatile range from wide-angle to portrait lengths.

Designed for photographers who want to replace multiple prime lenses with a single zoom—without sacrificing speed—it delivers fast autofocus, excellent image quality, and balanced performance for both photography and filmmaking.

G Master Performance

Sony’s G Master line represents its highest-performing optics, delivering exceptional sharpness, smooth bokeh, and fast operation. The 28–70mm f/2 meets these standards as a true multi-purpose replacement for several primes.

• Constant f/2 aperture: One full stop faster than f/2.8, improving low-light performance and depth-of-field control.
• Advanced optics: XA, Super ED, aspherical, and ED elements ensure high sharpness and smooth rendering across various subjects—from landscapes to portraits.
• Nano AR Coating II: Minimises flare and ghosting for strong contrast and vivid colours.
• Floating focus design: Maintains consistent image quality from infinity down to a minimum focusing distance of 0.36 m.
• 11-blade diaphragm: Produces smooth, circular bokeh.

Designed for Hybrid Shooters

Equally suited for stills and video, this lens includes features tailored for hybrid workflows:

• Four XD linear motors: Provide fast, precise, and quiet autofocus, supporting:
  • Continuous shooting up to 120 fps
  • High-speed video up to 240 fps
• Internal focusing: Keeps lens length constant during focusing for improved handling.
• Short-throw zoom: Lens extends only 1.8 cm when zooming from 28mm to 70mm—minimal enough to avoid rebalancing on gimbals.
• Reduced focus breathing: Plus support for Breathing Compensation in compatible cameras.
• Manual aperture ring: Can be de-clicked for smooth, silent operation.
• Adjustable zoom resistance: Switch between smooth or tight zoom control.
• Balanced weight distribution: Total weight is 0.91 kg, with emphasis toward the rear for comfortable handheld use.
