Voigtlander 40mm f1.2 Nokton Aspherical Review

October 12, 2017 | Mark Goldstein |

Sharpness at 40mm

Our sharpness tests were conducted using a 42-megapixel Sony A7R 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 almost the entire aperture range, with peak performance between f/2-f/11. Corner sharpness isn't quite as good, producing optimal sharpness at f/4-f/11.
