Zeiss Otus 55mm f/1.4 Distagon T* Review
Sharpness at 55m
Our sharpness tests were conducted using a 50-megapixel Canon EOS 5DS R 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.
The full frame at 55mm
Both centre and edge sharpness are incredibly high right throughout the entire aperture range, with peak performance between f/2-f/11. Only f/16 is marred slightly by diffraction.
