sticky focus ring in cold weather

[DM_rider]

Well, I was shooting in 30 degree weather today and the focus ring on the 170 gunks up. It wasn't even that cold! I don't even want to guess what happens when I shoot in 10 degree weather... It was almost impossible to get a smooth pull because the ring sticks when it gets cold and takes a good twist to unstick it and get it turning. Even with a follow focus, I still think it's going to be a problem... I'm not happy right now. It reminded me of a cheap fluid head in cold weather.

This never happened to me with the hvx200 either.

Edit:
Just tested it at 28 degrees outside, the colder it is, the worse it gets.

If it's cold enough outside, other 170 owners need to try this, I can't be the only one.
