Richard Sibley tries out Sony’s fastest FE lens for the Alpha 7-series full-frame compact system cameras
Test results: Distortion and vignetting
Distortion is very low indeed; our tests show a little barrel-type in the images, but you’ll be hard pushed to spot it in real-world use.
As is typical of a fast prime for full-frame cameras, vignetting is rather pronounced, reaching a maximum of almost two stops wide open. The falloff profile is also somewhat abrupt into the corners of the frame, making it very visible in real-world shots. Stopping down to f/2.8 reduces the effect significantly.
