As for the EL2, the non-AI lens feature wouldn't apply as it is an AI body.
I don't think anyone mentioned that the Nikon EL-2 is one of the few Nikon bodies with a movable AI coupling lever (just like the FE, FM, F3, and F4). There is a little button on the side of the lens mount, above the lens release button, that lets you move the lever out of the way, and then mount a non-AI lens for stop down metering. Nice cameras.
