I'm not sure what's going on with my camera. I tested it before making the shim adjustments in the viewfinder that I mentioned yesterday, and it tested fine with three different lenses. Spot on, actually. I took the camera out today and it was fine. So, I guess I just had a bad spell of operator error the other day, since I lack any other explanation.
Today it rained most of the time we were outside, so the cameras were kept stowed except for a few short exceptions. I was sheltering under a tree in the second shot. Here's today's catch.
