I do that much of the time, too... especially in a situation with unchanging light, where the meter might be fooled by the changing tonal values in the background... the hockey rink, for ex. When I use "auto" exposure modes (Av, Tv) my m.o. is always : "Trust, but verify." :) > > I have my camera set up so that the thumbwheel controls aperture, the front > wheel controls shutter speed, and the thumbwheel + ISO button controls ISO. > That part is standard.

I'm not sure how that's different from the setting up & chimping that I do without the green button... Sounds the same, except that I check the settings by looking at the meter in the viewfinder.

It's damn near like having auto > exposure on manual exposure lenses, truly a thing of beauty. Interesting. I'll have to look into that aspect... I only have a couple of old manual lenses, they don't see too much action these days, but maybe I'll try them out that way.
