Thanks Paul, but that equation doesn't seem right to me. Simply consider the case of a 90° FOV - for this equation to yield a 90° FOV the focal length would have to be zero. And according to the equation 12.7mm should give an 81.79° FOV.
This contradicts the results of the empirical tests already reported here, i.e. that for the dolly cam an exact 12.7mm focal length gives an exact 90° FOV.
The 3Dcheapskate (also available in DAZ and HiveWire3D flavours) occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
