[QUOTE="ScottinPollock, post: 480286, member: 40111"] So in Manual mode it seems pretty clear, but in P,A, and S, the settings are clearly lying to me. Scenario 1: Camera mode S; shutter speed set to 1/125, ISO 100 (no auto). Enter live view and start video recording; exposure is being controlled automatically. Display says 1/125, f3.5, ISO 100, but clearly there is not enough light for proper exposure, so what is being adjusted? I am guessing ISO... so can I count that my shutter speed will at least be fixed to 1/125? Scenario 2: Camera mode S; shutter speed set to 1/125, ISO 1600 (no auto). Enter live view and start video recording; exposure is being controlled automatically. Display says 1/125, f3.5, ISO 1600. Now frame much brighter scene and see fStop rise to as high f22. So can I safely assume the camera is actually adjusting aperture? What happens if light is great enough to over expose at f/22 @ 1/125, does it scale back the ISO at that point? Scenario 3: Camera mode A; aperture set to f8, ISO 400 (no auto). Enter live view and start video recording; exposure is being controlled automatically. Display says 1/60, f8, ISO 400. Now frame much brighter scene and see SS rise to as high 1/200. So can I safely assume the camera is actually adjusting shutter speed? What happens if light is little enough to under expose at f/8 @ 1/30, does it boost the ISO at that point? Scoured the web for this, nada? While I could experiment all day with this to try and determine what it is doing, I am hoping someone actually knows. To bad no EXIF timeline in video. [/QUOTE]
