Bought a 5DmkIII - the level doesn't seem to be correct...

MC Escher couldnt pick a worse shot to test level on.

Agreed.

Agreed that there is still convergence, but you'd expect the convergence to be toward the center of the frame, right? Maybe I don't understand convergence the way I think I do.

Agreed.

Good point too. Still, the left side of the tower is perfectly vertical in the original, and the right side of the tower is leaning left. The right side of the tower is in the center of the frame, and should be generally vertical unless the tower is tapered.

But were castle walls actually vertical? I remember seeing a documentary that showed the thickness of the walls diminishing as they went upward to reduce the load on the bottom and thus you get a slight tilt.

I will take a shot today with the level showing the camera is perfectly level. I will post later tonight.

Yeah, that's back to the "bad subject for this test" thing.

Taking a photo of a 4ft. level seems like a great way to go.
