I am getting a lot of fogging on the viewfinder because of the large rubber eyepiece. Anyone else experiencing this? I wonder if Zacuto has any plans to address this, ie. a textile version...
I was shooting in a hot humid environment and the only time that was happening to me was when the eyepiece was "suctioning" to my eye socket, making an airtight fit, once I unsealed my eye from the eyepiece, the fog would disappear. No big deal for me, I just positioned my eye so it wouldn't make an airtight seal.
That said, you can get anti-fog sprays and cloths at Sport Chalet. Scuba divers have the same issues with our masks fogging up underwater sometimes. Or you can always spit in your mask, then rinse it. I wonder if you could spit in your Z-Finder, then rinse it? ;-)
