Lovely colour rendition, good flare control and low distortion to my experience. But it does seem to have more pronounced field curvature than my other R lenses. And the field curvature appears to cause the in focus zone to curve away from the camera when moving away from the centre of the image. But I'm no techo on this stuff. With my other lenses, the curvature is both less and moves towards the camera, it seems. Could this be caused by gravitational differences between Germany and Japan? I'd be happy if this comment tripped a discussion on field curvature, in general. Do any of our more skillful users consider the field curvature characteristics of their lenses in day to day use? It strikes me that knowing where the field will be with a wide open wide angle lens could make for interesting photography. Regards Rick Dykstra
