I have an HVX200 and use a Century Optics .6x wide converter from time to time. I'm in the market for a Chrosziel mattebox and have been looking at the MB-450-R20, but I'm concerned it's not wide enough to use with my .6x wide converter. As I understand the MB-450-R20 can accommodate lenses as wide as 19mm, but that's 35mm Academy, and I have no idea what that converts to in HVX speak.
I've also been looking at the MB-450w-20, which is wider (16mm Academy), but it's a bit more expensive and I'd rather save a few bucks if I could. Is the MB-450w-20 even wide enough to use with the .6x converter on an HVX200? Does anyone have any suggestions or have experience with this type of setup? How would I even calculate the conversion from the HVX lens to 35mm Academy?
