comment What grease to use on zoom drive gears?
In the end I went with "cheap stuff that's likely good enough". Some sort of silicone stuff from a RC airplane friend. No point shelling out half the price of a new camera for a tube of unobtainium perfect lubricant!

Yeah, wikipedia's page on boron nitride mentions that BN lubricants can be an alternative where the conductivity of graphite is a problem. I assume it relates to that. But it's also irrelevant to lubricating plastic gears :)

comment How many moving elements in a Canon A490?
I later saw there were two solenoids. As you predicted, one controls the shutter (I didn't know digital cameras had or needed these!) and the other a secondary aperture. Image for the curious.

Couldn't help myself, opened the lens barrel further. Your ID is confirmed: the flex goes to a solenoid. I guess that's your aperture drive!

Thanks! Although the zoom and auto-focus are a bit different, just your pointing out that the flex going in might be for the aperture, is enormously helpful.
