They are supposed to run dry, however graphite helps where there's been slight corrosion.

Never use graphite! It's almost like a nano invader. It will make its way into the optics and it is a total b*tch to remove!

None. If rust is present remove the blades and remove the rust with 4-0 steel wool.Originally Posted by sanking

It does depend on how you use it, I've used WD-40 before now which is about the worst lubricant possible and that saved the shutter. If and when I use graphite it's extremely sparingly and any excess is removed, never caused any issue in 40 years. The blades only need a tiny tickle . . . . . .

Shutter blades are designed to run dry. There should be no lubricant of any kind.
Certain pivot and bearing surfaces within the shutter need very small amounts of lubricant.
That will be detailed in the service instructions for the shutter.
Don't ever use graphite for anything. It's the worst abrasive in the world.
For lubrication of that type use molybdenum disulphide (aka moly-D).

If you believe you can, or you believe you can't... you're right.
We used to lubricate rotating instrument bearings by diluting the oil in isopropyl alcohol. We would submerge the precision bearing and assembly, then drain and oven bake dry. Applicator syringe can apply by the drop or less. For diluted oil very fine layers can be accomplished. We watched the viscosity of the solution as the oil will coat the item making a layer and leaving less and less lubricant in the dilution.
Nothing personal but if you have to ask this question you really should have the repair done by an experienced service technician.

This seems to have become the latest holy war on camera fourums. I worsip in the church of no lube on shutter blades.
