I have a 35mm adapter and some lenses. I was wondering if there's a mathmatical equation to find out what the HVX+lens equivalent field of view is on a 35mm camera. I know that the field of view is dependent on the ratio between the lens and chip, so that a 50mm lens on a HVX is not equivalent to a 50mm lens on a 35mm camera, right?

I know that the the HVX is 1/3" which is about 8.4mm and a 35mm camera is... well... 35mm. What I dont know is how to figure out what lens I would need to put on my HVX to match the same field of view as a 50mm on a 35mm camera. If the ratio were to stay the same, that would mean I would need a 12mm lens on my HVX... that doesnt sound right. Please help!
 
Just use this formula and you will get it right every time.

LOL...I know that with the manual AI nikon lenses it is 1.5 times more on a digital camera. IE a 50mm reads as a 75mm lens on a digital camera. so on the HVX it could be something similar. You might try a 35mm lense and see if that simulates 50mm.
 
a 35mm focal plane has roughly 7x the field of view of that of a 1/3" ccd.
so at 4.5mm on the HVX the field of view is roughly equivalent to a 32mm focal length on a 35mm camera (I am guessing you are talking about a 35mm still camera frame).
