Sony has today announced their newest lens, the Sony FE 20-70mm F4 G lens for full-frame Sony mirrorless cameras. It offers a versatile focal range as a general walkabout lens with a constant f/4 wide open aperture throughout. Sony says it offers “impressive Sony G Lens image quality” with high-speed accuracy and tracking AF, with a design optimised for maximum mobility and operability.
The new lens, they say, is “redefining the standard zoom in our G lens category to meet the needs of today’s content creators”. Offering a slightly slower f/4 aperture over the typical f/2.8 certainly does come with some perks that many creators will find handy, given the ISO performance of many of today’s cameras. The two biggest advantages f/4 zooms offer over their f/2.8 counterparts are price and weight.
