The problem that a lot of people seem to have with the 58 is that they are looking at sharpness at test chart distances and extrapolating that to all distances. The sharpness of the 58 varies greatly with focus distance - at distance it is every bit as sharp as the 85 1.4G even at f/1.4. The field curvature also flattens.

It is meaningless to talk about sharpness of the 58 without the context of the shooting distance.

The problem with this is that nobody* shoots at f1.4 and infinity focus. Virtually every example I've seen from this lens is a picture of a person at relatively short distance.

For landscape use I think we can agree there are better choices.

Field curvature in portrait lenses doesn't bother me, since the subject isn't flat and the lens doesn't have to be focused at the image center.


(* I'm sure someone will go find a counter-example...)

Do you see any lack of sharpness of what is in focus in this image taken at around 2m?:
