Just to let you know. I have a DVX100B with a Epic housing for sale. I live in Orlando. Let me know if you are interested. As for DVX wake footage, They used a lot in the Truth, Esoteric was shot entirely on the DVX. The Chick Flick and Delta Sessions 2 I think as well. You can also check out the teasers for Pendulum and Box of Fun. Both of these are shot on the DVX with the exception of the slow-mo footage. There are a bunch of other wake films using the DVX as well. The DVX has a decent wide angle compared to most cameras but sacrificed the telephoto to achieve this.
Now for the Best camera "in the wake industry" (this is all opinion) Most of the top filmers in our industry are now using the Panasonic HVX. Justin Stephens, Sean Kilgus, Ronn Sidenglanz, Collin Harrington and Myself. Just to name a few who are using it.
You also might want to check out the DVX Users forum at
www.dvxuser.com You can check out all kinds of footage and find answers to almost all your questions regarding the DVX and HVX as well.
Best of Luck and get in touch with me if you are interested in checking out the camera.
