The Nikon F3, Canon New F1 and several Olympus OM models all do
TTL-OTF ambient metering. The unique feature of the LX is that it
does so down to -6.5EV, a range which is unheard of.
Don't know which F3 model you had. Mine metered off the screen, and
exposure was locked in when the shutter was pushed.
The F3 model did not meter off the screen, Bill. It was the first
Nikon with the metering sensors fully intergrated into the mirror
box, and also the first Nikon to support TTL flash metering. It
didn't do OTF real time metering, though: exposure time was locked in
at the time of the shutter release as you said.
The LX will adjust the exposure to correct changes in light
intensity *during* the exposure.
I don't know much about F1s and Olys.
The Olympus OM-2 did that, they were the first (1975-76, IIRC). I
don't know about the Canon F1.
