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* 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 or something else.
