Samyang AF 85mm f/1.4 EF review: Resolution, shading and curvilinear distortion

Resolution

Samyang AF 
85mm f/1.4 EF

The lens produced a poor set of resolution results wide open. As the solid red line on the chart shows, sharpness improves considerably by stopping down to f/2.8, with centre sharpness peaking around f/5.6. The Sigma 85mm f/1.4 DG HSM Art and Canon EF 85mm f/1.4L IS USM produce sharper results wide open and deliver far superior edge sharpness. Corner sharpness gradually improves to where it peaks between f/5.6 and f/8.

Shading

Uncorrected corner shading at f/2.8

Using the lens wide open at f/1.4 results in the corners of images appearing about 1.6EV darker than the centre. By f/2.8 corner shading is less severe and unrecognisable in real-world images. At the time of testing a lens profile was unavailable, but the profile for Samyang’s 85mm f/1.4 AS IF UMC lens was effective at correcting corner shading.

Curvilinear Distortion
