	I agree. I've been deleting like crazy over the past
	two days. But forgive me to make one comment regarding
	English (this comes from an originally non-native):

	To me, Eastland's sentence means that the region in space
	which is being photographed and which is being metered - is
	affected by which lens one has mounted. Changing the lens,
	changes the frame lines and shows which region in the real
	world is being metered.

	Oh. Maybe you got it also.

	OK. Enough of this. Let's go take some pictures and find
	out.
