Zeiss Milvus 18mm f/2.8 Review
Sharpness at 18mm
Our sharpness tests were conducted using a Sony A7R II body mounted on 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 18mm
Centre sharpness is high right throughout the entire aperture range, with peak performance between f/4-f/11. F/22 is marred slightly by diffraction. At the edges of the frame, peak performance is again achieved between f/4-f/11.
