Awesomeness. More positive karma for me and negative for him.

I held the mirror up while releasing the shutter at 1/500th and 1/1000th. Same effect. It's definitely the rear shutter curtain which seems to not even open up all the way. So it'll probably end up at KEH.

For everyone that thinks the shadow would be sharp at the edge of the shutter, here is a photo from my Spotmatic shot at 1/1000th which has the same problem (which goes away after you fire the shutter about 5 times.) The Pentax has a horizontal shutter travel.

It would be sharp with electronic flash. I tended to also think it was the mirror. In natural light there's no real reason why it would be sharp, if the shutter is dragging or hanging up, unless it were stopping altogether.

Nice shot of the dog, BTW.
