I've seen http://www.luminous-landscape.com/reviews/...70-review.shtml

and I'm not sure if what I'm seeing on my copy is typical or not...

I took these

http://camera.fotopic.net/c574855.html

Technique was to set centre focus point on the building (should have been near enough infinity in these cases, I think), focus lock (half press shutter in one shot focus mode) and recompose to get the building "target" in a different part of the frame. All reasonably fast shutter speeds, hand held.

All jpg, parameter 2, Av, AWB. You can look at the original. I've only renamed the files (no cropping, resaving, or anything else).

So trying to take a step away from the theory of how good L glass is supposed to be, and pixel peeping, if YOU have one of these lenses, is the lens I have showing typical performance, given the technique, do you think?

I know no lens is perfect. I know taking this kind of shot at f2.8 isn't what I should be doing other than as a test. I'm just trying to work out if my copy is typical or not. I don't expect perfection. But these lenses are not cheap, and I want to work out if this is as good as it gets, typically.

I've seen suggestions I should be taking pictures of newsprint, camera on tripod, mirror locked up etc, but even if I did that, I've know idea what I should be seeing as acceptable.
