ZIESS conquest - black crap on the lens
« 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

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.
