That's an easy definition - "very fast" here means it chills to below the dew point of my jacket interior in less time than it takes for me to take the camera out, take the photo, and return it to my jacket.
The actual temperature at which this occurs varies according to a complex formula depending on the bulk of my gloves (decreases camera operation speed), whether my eyelids are frozen shut (ditto), the particular coat I'm wearing (affects interior temperature), physical exertion prior to the photo attempt (ditt), and how much hot sauce I had on my lunch (hot curries increase perspiration and thus the RH% of my jacket interior). Below -15C is usually my danger zone, but it really depends. I'm waiting for an app to do the calculation on the fly, I think it would be a popular one.

Ooh, Windsor might actually be harder on a camera than my armpit
