Panavision Equivalent Focal Lengths Tool
Posted 26 May 2007 - 07:16 PM
and also Dimension to use in the Calculation.
Thanks guys, please help?
ps: I just want to check a 24mm, 50mm, 100mm and a 8 and a 9mm for Super 16, using 35mm still lenses

The Panavision calculator gives you the equivalent focal lengths, that is the lens focal lengths being used on different formats that give the same angles of view.
So, if you wish to find out how the angle of view of Super 16 lenses compared to 35mm still lenses, you select Super 16 as the "first Format", then 35mm Still as "Fomat". You then enter the shortest Super 16 focal length you wish to consider, followed by the "Increments" - the gap between the lens you want to be compared e.g. every 5mm. Following that, you enter the highest super 16 lens you want. You hit the calculate button anf you get a table covering the selected range.
You can work in either direction between the formats and between numerous different formats.

what is the 35mm still lens equivalent for a 24mm lens on Super 16?
and so forth how can we calculate this same equivalent with other lenses?

You just follow the procedure I outlined, beginning with your widest lens, you can put in the next lens in your set as the highest and the difference as the Increment. You can then work through all your lenses.
The alternative is to starting focal length at say 5mm and put an Increment of perhaps 5mm and go up to 120mm as your highest. You'll get pretty good range of lenses listed.

how you came to this conclusion?

focal length on 35/diagonal of 35 neg=focal length on other format/diagonal of other format
You can obviously alter the diagonal part to compare horizontal angle of view, too.
