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.
My Nikon F2s came with an eyepiece blind specifically to combat this problem, and to keep stray light from bleeding past the mirror during long exposures.
What happens is that the metering is done off the focusing screen, so stray light coming in the eyepiece can affect metering.
I'm of the opinion that any upper end camera should come with a closable eyepiece blind just for this reason.
Sadly, it seems they would rather listen to their accountants than the people who use the equipment.
As an aside, if you leave a K1000 sitting in a place where sunlight can hit the eyepiece for a few days, it will kill the battery, as the meter is activated by light hitting the photocell.
