my name is Olivier Vanaschen, I'm part of DP team called "the black sheep". We worked a lot with MINI35 adapters, we shot a short about two years ago with one of the first homemade MINI35 adapters, the short is called "Marla." ( http://www.marlathemovie.com
). We've since then continued to develop our own adapter and tested about every possible camera/adapter configuration.
I personaly wouldn't recommend the JVC because I really dislike its look but that's maybe just a matter of taste. The HVX200 is a great camera but I do prefer the Canon H1. The sharpness, color and overall resolution is just superb. It's also easier to use this camera handheld. I used the PAL version and the 25p mode was very convincing. The HD-SDI output is just amazing, I really would like to test recording to the Wafian uncompressed recorder ( http://www.cineform.com
Here's a link to a music video with directed and shot with a Canon H1/P+S MINI35/CookeS4 lenses: http://www.theblacks...taintedlove.mov
Nikon lenses would be really good, we use a set with our homemade adapters. It's fully possible to gear them so you can use a standard follow-focus,... The new Zeiss in Nikon mount should be amazing too.
The best is to test the configuration you have in mind in some kind of real-life production setup because a MINI35 adapter system can quickly become big/heavy and quite difficult to operate.
If you have any questions, I'll do my best to answer them.
