Q: I’ve heard mixed reviews on the Sony FE 24-70 F4 ZA OSS. How does it stack up against the competition? — Chuck

A: Lots of people are comparing it against the Sony FE 55 F1.8 ZA prime – which is one of the sharpest lenses I’ve ever owned. But in DxO Labs lens test comparisons against its competition – Canon EF 24-70 F4L IS USM and Nikkor 24-85 F3.5-4.5 G IF-ED VR – the Sony FE 24-70 F4 ZA OSS is ‘Best in Class’.
