I'm using a Canon 7D and have a question about metering in certain modes. When I'm in Aperture Priority mode, for example, with Auto ISO and a speedlight attached, the camera gives me no form of warning whatsoever if my exposure is way off before I take the picture. For example:
I walk outside mid-day and set the following:
Speedlight attached on camera hot shoe
If I half-press the shutter to update the light meter, it just has the line locked on the center of the meter at EV 0. Now I understand that is what the purpose of a non-manual mode is; to tell the camera to maintain a certain metering. But without a ND filter on my lens with the above settings, the shot would be WAY overexposed if I snapped a picture. However, before I snap the picture there is no form of warning whatsoever that the camera is not capable of achieving that exposure.
This was a little difficult to explain in words so I hope I made it clear.
