Title: ZIESS conquest - black crap on the lens
Post by: KFhunter on October 18, 2013, 11:06:25 AM

Other day, lens on the ZIESS conquest went black.  Couldn't see through it. It was cold humid morning where optics would be prone to fogging.

This was like a coating of soot, I had to almost scrub the gunk off so I could see through it.  Anyone got a clue to what happened?

I wonder if the lens coating somehow had a reaction and went black  :dunno:

.....you dropped your cigarette ash on it while hiking in, and with moisture, it froze during your walk :dunno:

actually it looked more like I held it in the exhaust of one of those rednecks dodge trucks that blow black soot out the exhaust



I don't smoke

so messing with it, seems to be the backside of the lens going black when the temperature changes rapidly.

got to be a coating

hasn't done it to me since that last time


was weird, like a coating had a chemical reaction to something and went black like rubbery soot.

Send it in. They'll fix it or replace it. No need to mess around.
