The last photograph

This is the last photograph I took with the GXR before it died.

It does seem to be that it is just failing to stop down the aperture.  Annoyingly this is clearly not a physical problem, because I can see it opening & closing the diaphragm when it's not taking the picture, so the lens is physically fine: something is just not telling it to stop down at the appropriate moment.  If you take pictures where the camera wants the lens to be wide open then it's fine.

This picture was from yesterday, so this is cheating a bit.
