My blizzard rescue of a frozen lens made me question workspace rules
I was on a ski trip when a client's zoom lens stuck solid from the cold. A lot of camera techs insist you must only fix things in a clean, controlled space. With just my pocket kit, I got it moving again right there in the snow. That was a year ago, and the lens still works great. I firmly believe that being ready to work anywhere is more valuable than waiting for perfect conditions.
That line about the best tool being the one you have with you hits hard. I was a total stickler for the clean room rule, always thought you were asking for trouble otherwise. Seeing your lens still work a year later after a fix in a blizzard completely flipped my view. Getting the job done with what's in your pocket beats waiting for a perfect setup every single time.
