enemies lens mushrooms
The biggest problem I face for the protection of my goals is the humidity.
Humidity is, however, in most cases only a means through which to spread the worst enemies of the objectives: mushrooms.
happens very often now reading the various forums to find people frigates by this problem, because the problem itself is seen that depending on the size of the colony over the image quality to deteriorate and cause problems similar to backfocus, in cases advanced can cause irreparable damage to the lens.
Recognition is not complicated, just look at the lens to 45 °, with the aperture so that light enters and if there are a lot of fungus or mold these eye-catching.
