If it's on the lens...get it off fast! Or ot will etch through the anti reflection coatung. Breath on it...and wipe it with that magic cloth.
Thanks Matt, Gary and Cricketfan - much appreciated
Well, I went to Bentley's Camerahouse at Indooroopilly and found two different cleaning kits. Upon asking which one would be the best for cleaning the D70 lens, I was told neither and they did not have anything suitable for a D70 * The way they said it was as if the D70 is to cameras as a Rolls Royce is to cars.
I do appreciate Bentley's honesty - thanks fellas!
They suggested breathing on the lens and using the microfibre to clean the remaining finger oils off.
Everything now looks OK, but I'm going to redo the lens in the spot where an accidental finger print occurred again shortly.
I think it is probably my fingerprint, but then again, someone took a few pics of the ceiling, wall, doorway and bar, and it wasn't me! So the offending fingerprint could have came from whoever did this.
Wife, son and daugher had denied any involvement. The dog looks awfully guilty though

Might have been a tongue print?
I'll pm birdy and see if he has anything left in his locker after your Sydney meeting today!
Cheers
Graham
