No. A press on the green button does a light metering that takes the aperture setting on the lens into account, and sets the camera to a suitable shutter time. That shutter time remains set until you a) press the green button again or b) change the shutter time manually with the Tv wheel. The shutter time does not change if you change the aperture. The shutter time does not change if the light conditions change. anders ------------------------- http://anders.hultman.nu/ med dagens bild och allt!
