What are actual dimensions of the following formats and chip sizes? I'm trying to come up with some accurate idea of what lens equivilents are and I keep finding #'s that significantly differ.
I'm interested mainly in the horizontal width and not in the diagonal or in numbers derived from assuming that a 2/3" chip is actually 2/3" (which it may not be.)
SLR full aperture
Academy - not projection but camera negative's image size
2/3" 16:9 chip (like an HDCam or varicam)
1/2" 16:9 chip ( like Sony Ex-1)
1/3" 16:9 chip ( like an HVX - didn't Barry discover the actual dimension?)
If you have numbers for 16, super 16, & super 35 that's OK also but the ones above are the ones I care about .
Here's some guesses from stuff I was able to glean & it matches some of my observations. The 32mm figure for SLR I got from a Panavision FOV calculartor and it suddenly made other numbers work. (BTW I've changed these numbers a few times since I poosted about 1/2 hour ago.)
SLR full aperture - 32mm
Academy - not projection but camera negative's image size - 24mm
2/3" 16:9 chip (like an HDCam or varicam) - 9.6mm (read this on the web)
1/2" 16:9 chip ( like Sony Ex-1) - 7.2mm (derived from the 2/3" size)
1/3" 16:9 chip ( like an HVX - didn't Barry discover the actual dimension?) - 4.8mm (just halved the 2/3" )
