But, as soon I start to walk following the talent I have shaky shots. I have the same problem, I don't know how to walk, or it's caused by my equipment?

So great news!

Sometimes some companies didn't give a official announcement in time when they upgrade their firmwares and add features to older models,etc. But I still like sony band. In generall, the products are not bad. If you want to shoot your snowboarding trips, there is a good choose for you: http://goo.gl/w2bKzV.

Maybe, it also offers what you want. http://www.newfrog.com/c/lenses-accessories-16.html

It's perfect, but no talking about setting.

Canon 5D with 50/1.4 may be ok.
