90 degrees FOV at 11 mm? (D5000 w 10-24mm DX lens)

Nice test, mcammer. Now how will you check that the focal length is really 11? (just kidding ;-)
Ah, a Socratic temperment married up with a physicist's precision. A result and a correction is still two publications jonny!
(not shown- intermediate shots where i was trying to find when 11 rounded up to 12)
Ah, I'm facing the same issue here. However I'm pretty much set on the Tokina 11-16. Just waiting for a little bit more research
Hahaha! You're right, mcammer.
Your method works for me. I wonder why in the metadata they don't save the focal length info to three digits of precision on the wide end like they do on the long end (I mean, I might see 136mm but not 13.6mm). Probably I'm the only one who cares, but it could have saved you a couple of shots in this case. By the way, I'm impressed by the flare handling in that shot. How far off the frame is the sun?
Really, all the information was already there for you... ;-)
Angle of elevation for that time of day at 42N 84W is 48.7 degrees
Vertical field of view for that lens at 11mm is 72.1 degrees. Since horizon is in middle of pic, sun must be another 13 degrees higher.
Sorry about that all other NR readers!
I can't even begin to comment on how nerdy your last comment was, mcammer. Unbelievable.
(Did everyone else stop reading? Oh, good. Your last comment was awesome!! What can't you figure out with the right metadata?)
