I've never owned an LX, :-( so I can't be certain just how the OTF metering works. If it indeed waits for stop down and reads the light level from the film or shutter curtain then yes, it should be a fair test with either lens. Perhaps one of the other PDMLers will be more helpful here. I was led to understand that OTF only works at certain shutter speeds, but perhaps that was just for TTL flash.
