Hi All,

Just a quick question as I know very little about how lenses are put together etc.
I took my samyang fisheye out for the first time today and when I first took it out to shoot I noticed the center of each shot was misted.

After about 10 mins is seemed to clear ok, but is this normal?
I can understand misting on the OUTSIDE of the lens but not sure I like the idea of it inside?!
 
so you took it from a warm house to outside in the cold then, if so yes, when you go from outside to inside i always carry a big ziplock bag with silica gel in then put it in there andseal it before i go in the leave on side to come back up to room temprature, just open the zip slightly after a while.
never leave them in a bag if you have been out in cold always take them out when they have warmed to room temp and leave to air out.

Brill, I had read that trick but wasn't sure if it just applied to misting on the outside of the lens!

Thanks for confirming :)
 
Also, unsealed lenses can get moisture inside, the lens will then mist up as the water slowly evaporates.

I had this once with a Canon 55-250, after a soaking wet shoot in snowdonia (after someone left my bag open!) but it cleared after a few hours sat in the open warm air and was fine ever since.
