Focal
Length Chart
Is there a chart that compares relative focal lengths between
35mm, 16mm, 2/3" video, 1/3" video, and 1/4"
video. Doing scouts and research and planning in one format
for production in another necessitates this. The directors
viewfinder goes to 2/3", and 1/2", but now that
there's DV
Seems like someone has done this at some point.

Here's a comparison chart of Canon's website for 35, 16 and
2/3" video :

WOW! Nice chart!
Print it out.
I would really like to have this lens in my kit :
HD: 4.7-52mm = 35mm: 11.6-129 = 16mm: 6.2-69mm
Nice range!

There is an infinitely useful wealth of knowledge on the Panavision
New Zealand website (
www.panavision.co.nz). The heading
"knowledgebase" has tons of useful stuff.
The focal
length calculator that is precisely what you'd want is under "TABLE OF EQUIVALENT FOCAL LENS AND AOV". There's
also a great DOF calculator that can be set for any format
that I've used to make HD and MiniDV focus charts.

Some other handy stuff there too

With apologies to Geoff ...
Dare I say it, but you will find a complete nomogram covering
all these formats, and angles of view, and picture widths/heights
and subject distances on the back of the Samcine Mk. III calculator
... and depths of field for both fixed focal length and zoom
lenses for 1/500, 1/1000 and 1/2000" Cs of C, and much
more ...
