[Leica] Thumbs down for Lens Pen!

[vick.ko at sympatico.ca (Vick Ko)]

Politely speaking, it isn't going to affect your images.

It will affect your bench MTF testing, in comparing to a pristine factory 
standard.

I've always like clean glass, and have had to balance off the risk of 
putting cleaning marks on the glass, versus cleaning off fingerprint grease. 
  It does sometimes take a bit of a solvent to get it all off, and Windex 
hasn't ever failed me.

Good luck, and be gentle.

Vick
