Hello all!
So it's that time of the year again... winter is fast approaching and weather is getting colder and it's more windy outside for sure.
Since this will be my first winter with my D-SLR and my lenses, I was wondering if there are any things I should keep in mind in regards to shooting outdoors in extreme cold situations.
Have you guys ever had focussing or USM or mechanical issues with lenses, L lenses in particular in the cold outdoors?
I hope this thread opens up some discussion for shooting in the wintertime and perhaps some ideas on shooting winter situations/landscapes too! 
Cheers!
