What the heck is this large light spot in the center of my image? Three very similar pictures show the same thing. I've not seen this before in any of my images, even the images taken a few minutes earlier in the evening.
No CPL, just a B+W MRC filter that's been on it through all my shots since I've had it.
Thoughts?

I've had the same thing happen to me on a couple of occasions with this lens - both with and without a UV filter. I only use UV filters in areas such as sand dunes, and I photograph in those areas very rarely. I know for certain the other occurrence was using no filters at all.
This is not a filter issue. It's something with the lens, and as you said, only happens in very specific lighting scenarios.
Over at dpreview there were talks (quite a while ago) of a vignetting occurring with this lens and to turn off a specific setting. I've turned that setting off, but haven't really shot landscapes with the 100-400 since that, so I'm not sure if that resolves this issue for me. (or what the setting was - but there's a long discussion of vignetting with the 100-400 over there)
While I love the lens overall, this issue with my lens has removed a bit of confidence for me to use this lens in landscape scenarios. We'll see because I'm taking it to Grand Teton, Yellowstone and Glacier for a week and a half...
Exactly. Every once in a while I get these results under certain conditions and it takes away a bit of confidence with a lense that otherwise is outstanding. I've seen this kind of thing before and it appears to me to be a reflection from the sensor surface back reflected off of the diaphragm and back to the sensor.
