Zoom lens for Super35 from CANON [Patent]
Canon filed patent of zoom lenses for Super35.
At first, I showed this patent was for APS-H sensor. But that was careless mistake of my calculation.
Super35 is the correct sensor format.
Thanks for Mistral75.

Hi there
Thank you for your admirable work。 A precision though: for a cinema lens,
Image hight: 15.55 mm constant
corresponds to the Super 35 motion picture format, not to APS-H。

Dear Mistral75,
Thanks for your comment.
Simple and careless mistake of my calculation.
As you mentioned, sensor format is Super35 not APS-H。
