I used a small-sized video camera SONY CX900 at Mt. Tateyama.
Here are the tools I used with the camera at that time.
These are mont-bell’s “Two-way Pickel Leash”(the blue one) and
Black Diamond’s “Nitron Quickdraw”(the one with purple carabiners attached).
I learned about them from a book written by a Japanese photographer.
And I actually tried it and found that it worked very well for the video shooting
in the mountains. T.S
