Focal Length Multiplier for 1/3" and 2/3" Cameras

[drew_town]

Hey everyone,

 

Could someone please tell me what the focal length multiplier for a 1/3" camera and a 2/3" camera is compared to the standard 35mm camera? Thanks.

Hey everyone,

If you're talking about the standard 35mm movie camera, not FF35 still photography, then I believe you'd divide the 35mm focal length by 2.5 to get the 2/3" equivalent and by 5 to get the 1/3" equivalent.

 

But there are conversion programs to figure this stuff out, like at:
