will this work..?

[mateobishop]

I have a new dvx100b and am getting a matte box for it. A lot of those out there are 16:9 format which I won't be shooting in all the time. Will those still work and not be in the way if I'm shooting 4:3 ? I am specifically looking at this one. Any problems with this matte box on the dvx in 4:3 mode??
Also, does it sit on the rods and screw into the lens..how is it secured?
