Sony announces new ultra-wide standard zoom

The FE 20-70mm f/4 is Sony’s latest G series lens for photographers seeking extra width

Sony has announced its newest standard zoom, the FE 20-70mm f/4 G, which offers a constant f/4 aperture from ultra-wide 20mm through to 70mm. With promises of high image quality, efficient autofocus and user-friendly handling all within a compact body, the FE 20-70mm f/4 G will appeal to still photographers, videographers and vloggers alike.

Image quality

The FE 20-70mm f/4 G boasts a 20-70mm zoom range, with the 20mm end offering a 16:9 (2.35:1) aspect ratio. A minimum focusing distance of 0.25 metres (fully extended) and a maximum magnification of 0.39x add to its versatility.

The nine-blade circular f/4 aperture, combined with Sony’s XD (eXtreme Dynamic) Linear Motors technology and full-frame sensors, reportedly delivers high image quality and pleasing bokeh at any focal length. The lens contains seven elements — two AA (Advanced Aspherical), one aspherical, three ED (Extra-low Dispersion) glass and one ED aspherical — and also features flare and ghost resistance.

Auto focus and video

According to Sony, the 20-70mm lens improves upon previous models’ thrust efficiency and tracking performance by offering faster, quieter, more consistent AF, while XD Linear Motors are said to reduce both noise and breathing. When combined with the Sony Alpha 1 camera body, the lens can capture fast-moving subjects at 30 frames per second or record video at a similarly high frame rate. Additionally, for photographers who prefer manual controls, the zoom, focus and aperture rings allow for direct, immediate adjustments, which could prove especially useful while shooting video.

Operability and reliability

The lens includes several features designed to enhance user customisation and control. Two focus hold buttons — as well as an auto to manual mode switch — could prove handy when adapting to dynamic conditions, while an Iris Lock prevents accidental changes. The lens additionally supports the use of compatible polarised filters and is dust, moisture and smudge-resistant to increase protection against external elements.

Pricing and availability

The FE 20-70mm f/4 G will be available in February at authorised Sony dealers for an estimated retail price of £1400. Learn more at Sony UK.
