Shel,

The simple explanation is usually the one to go for. The aperture is set by the lens. The camera's only input is to activate the stop down lever, and I would guess that that is something that either works or it doesn't.

The camera of course has to fire the shutter at the correct speed, and I would think that an intermittent problem here in such a well-tested and common mechanism is rather unlikely. Again, these tend either to work properly or not at all.

So, in my view, and assuming it's not a sudden light shift, as Kostas suggested, it comes down to the lens. You exercised it AFTER the event, so it's working properly now, but it might not have been when you took the picture.

Hi John,

Not that I can tell, but I did exercise the lens for about 100 cycles after
seeing this just to be sure.  The aperture is certainly working fine now.
My concern isn't so much that the lens may be at fault so much as that
there may be some odd behavior that's an issue with these cameras.

It looks rather as though the aperture didn't stop down fully.  Sticky?
