Re: Much ado about nothing

What I didn't show you is that the foreground corners in that shot are sharp...

Its IMPOSSIBLE that that is due to focus error, the middle tree is sharper than the nearer tree on the bank.

You can focus on the sides instead, if you are aware of it, you'll throw the center out but have more chance of it being within the DOF. You can get a better result than this - I didn't shoot these as a test, I wasn't expecting problems. If you do the test inside, 2m away, 5m away, the effect is minimal. At 50m you can clearly see the effect of focusing for the sides or the middle.

Maybe my copy of the lens is worse than others in showing the field curvature but I do know what I am seeing IS field curvature.

Cheers,Andrew
