Anyone chipping AI(-S) lenses?

Nope, only Ai-S lenses will meter correctly...

... because of the linearity of the aperture. The way the aperture prong on the lens will cover is different between Ai and AiS lenses. All Nikon AF lenses are AiS lenses because of the linearity of the AiS lenses.

Chipping Ai lenses will work but the exposure will be slighly wrong. The amount of the failure is dependent on the aperture you dial. The failure nearly wide open is small, stopping down more and the difference will be greater.

best regards
