Originally posted by Gooshin getting to know the camera better i realized the other day how BIG of an impact having the viewfinder open to light has on exposure, with sometimes as much as a 3 stop difference working off a tripod!
just by blocking it with my thumb i see the readings change drasticly.
my next purchase item will be a cupped eye-piece to eliminate light streaks during regular use.
Gooshin, forgive me, but I don't understand what you're reporting. It sounds as if you're saying that it makes a difference to the metering if the finder in the back of the camera is covered (say, because my face is pressed up against it) or not (as when I'm shooting on a tripod and NOT looking through the finder). Is that what you're saying? How could that be? The meter doesn't react to light coming in through the back of the camera does it?
I just did a quick test here. I held the camera up by a window. It's bright outside and dark inside. I pointed the camera toward the inside of the room (dark) with the finder pretty close to the window and thus getting hit by the bright light from outside. In P mode, I get the same meter reading whether I cover the finder with my hand or not. This is with a K20D.
What am I missing here?
By the way, I do have an eyecup on the camera but I don't see how that would matter.
Thanks,
Will
