Hello, I just received a Canon AE-1 and wanted to know if the light meter on the side of the viewfinder only works when the lens aperture ring is set to "A". I want to be able to control both aperture and shutter speed. I do know when I take the lens off of "A" the led "M" flashes letting me know that I am in manual control. When this happens does this mean the light meter is disabled?
With my Pentax K1000 I would set the aperture and adjust the shutter speed until the needle was in the center and then write that combo down and adjust my DOF from there. Does the Canon AE-1 work the same way; you know the needle in the center?
I just want to completely understand this camera before loading a roll.
Thanks for your help,
