Hi

here we go, another crop factor my mind is exploding thread. I'm used to my full frame canon and its quite easy to calculate the lens taking it into a 3d program to match, as all numbers are based around fullframe in it. What would be the correct focal length equation for my black magic pocket cinema camera using a 24mm full frame lens and a speed booster xl 0.64?

In the 3d program I have my lens information and the camera have a setting for aperture in mm, it defaults to fullframe 35mm using 36 x 24mm

I enter 18.960x10mm for my Pocket cinema camera 4k as that seem to be the sensor size found on the specs sheet

would the formula for calculating the lens be 24 x 0.64 = 15.36

or 24x2x0.64= 30.72 as I already defined my sensor size ?
