"real " cameras in xsi 2005-06-14 - By Bruce MacDougall
Back
The most comprehensive table of Aperture and Finder Marking sizes I have yet
encountered is in "David Samuelson's 'Hands-On' Manual for
Cinematographers".

I have an old, weathered, marked-up photocopy close at hand at all times,
but it lists film formats only.
For video sensors, here are some standard widths (you can compute height
from aspect ratio):
1/3" Video (4:3) 4.8mm
1/2" Video (4:3) 6.4mm
2/3" Video (4:3) 8.8mm
2/3" HD Video (16:9) 9.59mm
I got these off the back of a Canon Lens Focus Chart.
Also keep in mind that frames produced by a "proper" film scanner, for film
work, are most likely full-aperture (is the image 2048x1556? can you see
slight imperfections around the edges and/or radii in the corners?),
while images produced by a telecine for broadcast work could very likely be
digitally "zoomed", which would throw your aperture size out the window.
Further clouding of the issues involved in manual camera tracking can be
found here:
