Sony Releases its First GM Zoom With a Constant f/2 Maximum Aperture
A look at the new Sony FE 28-70mm f/2 GM and how it could be the perfect all-arounder pair for the new a1 II.

Sony FE 28-70mm f/2 GM
Along with the announcement of the company’s new flagship mirrorless camera, Sony has presented a new FE 28-70mm f/2 GM as the ideal speedy standard zoom lens to accompany the new a1 II.
And while we’ve covered the Sony a1 II already, let’s now take a moment to look at this zoom lens option and its constant f/2 maximum aperture which is set to make the lens an ideal all-arounder option for those looking to get the most range and diversity out of a potential purchase of the a1 II.
Introducing the Sony FE 28-70mm f/2 GM
Announced as Sony’s first GM zoom with a constant f/2 maximum aperture and set to feature a useful wide-angle to portrait-length range, this high-performance all-arounder should be a good deal faster standard zoom option compared to the conventional f/2.8 lenses you usually find for flagship cameras these days.
The lens would be ideal for photographers or videographers alike looking to replace a set of primes with a single zoom without sacrificing speed. The Sony FE 28-70mm f/2 GM should be able to cover some of the most frequently used focal lengths, offers impressively fast AF, and is overall a single, well-balanced option for photography and filmmaking needs.
Designed for Hybrid Shooters
As is the case with the a1 II, which Sony is marketing as a versatile hybrid camera for all types of shooters and content creators, this FE 28-70mm f/2 GM should really fit the bill as a just-as-versatile zoom lens option which includes several useful features in its design to benefit its hybrid use, including:
- Four XD (extreme dynamic) linear motors generate fast and responsive AF performance that's equally quiet and smooth. The focusing system is compatible with continuous shooting speeds up to 120 fps or high-speed video recording at up to 240 fps.
- The internal focusing design promotes quicker focusing speeds and maintains the lens length during use.
- Short-throw zoom design means the lens only extends 0.7" when changing from 28mm to 70mm positions, meaning, despite the lens not being a true internal zoom, you still do not need to adjust gimbal settings when changing the zoom position.
This new lens is also set to feature Sony's G Master designation which is reserved for its highest-performing optics and should offer great sharpness, smooth bokeh, and impressive speed, to further impact its overall performance.
