Frost on Lense?

I attached a picture of what I seeing this morning. Any idea why the lease appears to be frosted. It wasn’t that cold here and other cameras were ok at the same time.

Curious that only one camera was affected in the same environmental conditions. May I suggest wiping the lens with a soft microfiber cloth. Do not apply any type of cleaner to the cloth. Perhaps some fine dust accumulated on the lens.

Recent advances have revitalized the capillary model, such as the engulfment model and the concept of geometrical supercooling. Key experimental and theoretical challenges remain to be resolved MyFordBenefits Login
