This lens is a good performer from center to edge, although not quite as sharp in the center as some newer 24mm lenses I've tried, and it does need to be closed down by a stop or so (I should note my specimen has a soft spot in its left quarter, presumably this is an individual problem with my less-than-pristine sample). Build is very good, slight chromatic aberration can show up towards the edges but not to any great excess.
