Not sure where this ought to go, didn't see a troubleshooting forum.
In any case, on vacation last week my camera took a dump in a pretty cold semi-wet setting. Was at a waterfall, it was snowing lightly, camera died on me.
Took the batteries out, let it set over night, it came back mostly fine, with the one exception being that the aperture won't go wider than 4 with the tokina lens I was using while it died. Tested other lenses which all seem to have full aperture range.
Tell me I didn't bork my new tokina 11-16 f/2.8.
FWIW, the body is a canon 50D and the lens is a tokina 11-16 f2.8 dxII (which was great for the landscapes I took in Iceland).
Not sure if related, but in the illumination correction settings my 50D seems to think the lens is a 12-24 for some reason.
