Fuzzy focusing

[Steve Hamley]

Gelatin soap. Moisten a cloth, get some soap on it, and rub the GG. Let dry and buff with a clean cloth. Any soap will do, but some leave streaks.

Has to be re-applied fairly often, but it works.

Cheers, Steve

In regards to the last post...before you do, make sure it's the green waxy stuff designed to be used on motorcycle helmet visors.

Definitely don't use...well, you wouldn't anyway.

Here, I should have included this:

This "superhydrophobic" stuff would do it. I'm not sure it's available yet, but it's supposed to be soon. It's pretty exciting stuff and seems to have lots of potential uses, including keeping water off of your focusing screen...

fogging is frustrating, but when temperature drops belove zero and GG gets instant ice coating, then the real difficulties begin..

A thin electric wire around the GG would give enough heat to prevent fogging and even icing, but havent tested.
But i know that such systems are used by star photographers to prevent lens from fogging/icing during really cold winter nights.
