Sharpness at 35mm

Our sharpness tests were conducted using a 24.3-megapixel Sony A7 Mark II body mounted to a tripod. The camera’s shutter release was also set on a timer-delay to avoid any possible camera shake. The test subject was shot using ambient lighting, hence some colour and contrast variation is to be expected between apertures.

Centre sharpness is impressively high throughout the aperture range, though apertures between f/2.0 and f/5.6 are marginally sharper. Corner sharpness is also very good, but fringing is noticeable at f/1.4 and f/2.0 when viewing at 100% image size. This has disappeared by f/2.8 and the lens goes on to produce optimal sharpness at f/5.6.
