I always got a kick out of people who wear glasses and pay big bucks for
a "scratch resistant" coating on plastic lenses. The coating is actually
called a hydrophobic coating and does absolutely nothing to make the lens
surface "harder". All it does is adds a bit of lubricity to the surface
so dirt or dust will tend to slide off rather than scratch the plastic
surface.

Wiping them with mineral oil will do the same thing.

Eisboch

That sounds like me.
Would that mineral oil affect the UV coatings?



No. Wipe it on gently and then off gently.

If you paid for a "scratch resistant" coating, you were probably also given
a small bottle of "refresher" or something called similarly. Guess what's
in the little bottle?

(As I raise my hand) ME ME ME , Eisboch call on me.

Is that the same stuff my mother made me drink when I was a kid?

JohnH,
I hate to interupt this discussion of laxatives, but did you ever take
that photo class Nikon was offering? I took the D200 class Nikonian
Academy http://www.greaterphoto.com/ gave and it was a great course.

No, like a dummy, I didn't. I just looked and it doesn't look as though
Wash DC is on the agenda for next year.

I took the 18-200mm VR on the Disney trip. I don't know if I'm satisfied
with the sharpness of the lens. Actually, it doesn't make any difference
because I used it for about 450 pictures during the week. I'm thinking of
sending it to Nikon just to have them check it out.
