Sigma 28mm F1.8 EX Aspherical DG DF MACRO A-mount lens review by Malina DZ
|Malina DZ#12108 date: Jan-25-2015|
flare control: 5
|ownership:||I own this lens|
|compared to:||Carl Zeiss 2/28 ZE|
|positive:||Excellent distortion control for a 75° FOV lens.|
Round aperture shape when closed down.
Very good flare control. Good sharpness wide open in the center of the frame, decent in the corners.
|negative:||Push/pull AF/MF mechanism and requirement to keep the lens in AF mode when switching a camera on/off. I don't follow Sigma's instructions and so far nothing happened to the AF motor. Sharpness doesn't increase by stopping the lens down. At f/5.6 your average zoom lens may capture sharper images. |
Focus throw is only 90°.
Inconsistent AF accuracy in good light.
|comment:||I did a comparison shoot out between Sigma 28/1.8 on a850 and Carl Zeiss 2/28 ZE on Canon 6D. My comments and sample DNG files can be found here: http://goo.gl/xkO2AQ|
