Morning all,

Does anyone have a reliable way of equating given focal length to houdinis
cameras. Or maybe a look up table

I  have a shot and I am unable to track and get the info that way.

The shot info is limited, but I have been given,

lens - 40mm
medium close up focus - 5 feet 6 inches

I know it is shot on a phantom high speed camera with a a inch x inch sensor
producing a 1024x1024 image.

Any help would be very welcome
