Focal Length Chart

Published : 13th June 2004

Hi,

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.

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 ...

Sincerely
