In-depth review of the Canon EF 14mm f/2.8L II including flare, distortion, field curvature, resolution charts, numerous field examples and comparison to the Nikon 14-24mm f/2.8G.

The review is as much a “user guide” as a review; even if you use this lens it’s well worth your time to read this review..
