I need to be able to calculate the focal length for CCD cameras
in all professional formats (1/3, 1/2, 2/3, 1" -- am I missing
any) and I thus need the recordable size of the CCD chip at any
given aspect ratio.
I was able to find the following, which appears to be for 1.33 aspect
Does anyone know if :
1) The sizes listed below are accurate
2) Whether they vary at all between different makes/models of cameras
3) Whether the normal focal length calculations for film work for
4) whether I can just adjust (downwards) the height of the CCD chip
for filming in other aspect ratios?
CCD size (HxV) :
1/3" CCD = 4.8mm x 3.6mm
1/2" CCD = 6.4mm x 4.8mm
2/3" CCD = 8.8mm x 6.6mm
1" CCD = 12.8mm x 9.6mm
Any/all information or direction as to where I might find this information
would be greatly appreciated. Also, is there anything special I
need to know about HD cameras and their CDs?
Thanks in advance,

Maybe you can compare your data with the database from PCam/Pcine
It contains film and all video formats incl. HD...

Thanks Florian for the suggestion of David Eubank's wonderful PCam,
which unfortunately only solves half my problem.
While I'd gotten a lot of information from PCam already you spurred
me to go back to his site and while it has been updated with very
useful HD format information--which, as I say, solves half my problem!--I
am still looking for the corresponding 1/3, 1/2, 2/3 and 1"
CCD data which I can't find on his site nor in the software. If
I'm missing it, please tell me where!
So if anyone else out there has information as to the recordable
widths of each of the above mentioned CCD at standard aspect ratios,
I would greatly appreciate it.

Never mind. I DID find the CCD data in PC Cam. I just had to change
the preferences for the camera from FILM to Video.
Thanks again for all your help.
