Lenstip is one of the best review sites you can find. And they just tested the new 16mm f/1.4 E-mount lens:
The Sigma C 16 mm f/1.4 DC DN is not a flawless device; especially in the area close to f/1.4 you can find several distinct shortcomings. Still you have to remember that those shortcomings disappear on slight stopping down of the aperture and image quality improves very quickly too. As a result this lens’s resolution levels are close to record values on both types of sensors and we mean here records achieved by lenses several times more expensive than the tested one.
Pros:
- good quality casing,
- sensational image quality in the frame centre,
- sensible resolution on the edge of the frame,
- slight lateral chromatic aberration,
- moderate vignetting,
- nice out-of-focus areas,
- silent and fast autofocus,
- good price quality ratio.
Cons:
- a bit too high longitudinal chromatic aberration,
- not completely corrected spherical aberration,
- too high distortion,
- coma visible in the corners of both types of detectors,
- noticeable astigmatism.
