anyone know how the dvx's Z00 to Z99 convert into milimeters when talking about lenses?

It's in the DVX Book, if you have that. Otherwise, I know a chart was posted here once upon a time but I didn't find it in the search...

really? damnit. I indeed bought ur book (awesomely helpful btw) but have since misplaced it. I have the dvd right here, but I've been looking for the book for a couple months now 
I'll do a search, but if anyone else knows where this is, please let me know

awesome, THANKS BARRY!
Barry, is this for 35mm film as in what I'd put in an SLR (36X24mm film) or 35mm film as in the considerably smaller frame of 35mm motion picture film?
The reason I ask is because I'm going to be doing some steadicam shots (a whole bunch of them) with a 35mm adapter. While I'm going to be using a 28mm f2.8 lens for most of them, I'll be required to use a 35mm lens for some shots (SLR lenses) because I need to shoot at f1.4 for night scenes in order to get enough light to shoot and I can't find a 28mm f1.4 lens I can afford.
I've found the 28mm lens to be wide enough, but if I zoom in at all with the dvx, it's not wide enough. Will the 35mm lens work at all (with the mini35 we used a 17mm and 35mm and the 35mm seemed quite like a 50mm SLR lens, so this makes a big difference to me.)
Thanks, and sorry for the redundant/convoluted question.

That chart is attempting to equate DVX field of view with 35mm still photography. Cine cameras have a much narrower field of view, of course, which necessitates using wider-angle lenses. The multiplication factor is around 4.4 for matching the field of view with a 35mm cine camera (so, 5mm on the DVX = about 22mm on a 35mm cine camera).

ahhh, ok well if i'm using these measurments for Sketch Up, where I'm adjusting the focal length of an Arri 35mm cine camera (the only option for 2.35 framing) would the measurements be different?
When playing arounf with the focal lenth in sketch up I wasn't sure if it was my imagination that it didn't look like 30mm from the arri looked like 30mm from the DVX (using that chart)
This assumes the programs accurate too

Yes it would be different. If you look at the DVX settings and compare them to the 35mm settings, you'll see that they're about 7.2x different (10mm on the DVX ~= 72mm on the 35mm still camera). For cine work, use a 4.4 multiplier instead (10mm on the DVX ~= 44mm on the 35mm movie camera).
