The focusing chart shots were done with a 16-45mm on autofocus and the leaf shot was manual with a 90mm lens at f2.5. I manually went out of focus each time, then let the autofocus zero in on the centre bit. They were taken from about 1 meter away.
In the garden shot I focused very very carefully (from about 2-3 meters away) on the 5 leaves together that are somewhat brighter than the rest and approx. in the centre of the pic. Notice its the leaves beyond that that are the sharp bits, and the focusing chart should speak for itself.
I'm not having you on, and I've had the camera for 6 months and probably should have noticed the problem by now. Where it finally came to light was using a tripod and f2.5 aperture and the subject was just not quite right in any of the pics. I had him hold a CD with text on it about an inch or two in front of his face and I focused on the text. After that all the pics were perfectly focused.

You claim you can detect an error of one inch in six yards. That's approximately 0.5%.
First, I'm amazed you can measure such a small focussing error so accurately, and second, at that distance the DOF will ensure that there is no problem. Or are you the fortunate possessor of a lens with a focal length of 1:0.2?
I am beginning to suspect a wind-up.

Doh! He's only painted on, so he won't be around much longer.
What is really funny is the pagans getting upset about it - whilst the Giant is not an ancient figure at all but a joke against Cromwell.
I like the photos though ChrisA - did you have to fight your way through the crowds to take it?
This isn't at all funny; it's just a cynical marketing ploy.

he, he... dunno if I can get that past the wife. But I suppose for the price of the DA* lenses, the extra body won't even be noticed.
Now, just have to figure out exactly where can I sell that second kidney?
