[Leica] Thumbs down for Lens Pen!

[hoppyman at bigpond.net.au (G Hopkinson)]

Very likely you may not identify any loss of quality at all in practical use 
from what you are describing. For cleaning fingermarks,
I use the Zeiss optical cleaning mixture with microfibre cloths. I find it 
to be excellent. You can get Zeiss moistened wipes in
sachets, too. I think someone may have mentioned them. I bought a couple of 
hundred off the bay a while back. They are really easy
to carry and effective to use. While you are being careful, be sure to use a 
clean soft brush to gently remove any dust or grit
before you wipe with anything. Plenty of people on the list will tell you 
that modern Leica lens coatings are tough and I have no
doubt that is true. I am always careful cleaning, maybe more than I need to 
be, but there is certainly no harm in it. I have never
scratched any lens over quite a few years of camera handling.

Ok, upon close inspection with a pen light through the front of the lens, I 
still have some oily residue left over. Looking at the
lens directly on held to a light source like a ceiling lamp, the lens looks 
very clear all the way through, but with a pen light a
see some slight leftover stuff, including dust in my lens. 

I don't recommend anyone use a pen light with their precious lenses if 
they're in anyway obsessive. You won't like what you see! Am
I being obssesive about my lens, or should I order some ROR and a new 
microfibre cloth from BH photo? Will it affect picture quality
is what I'm asking?

Thanks,
G Medina
