Zoom setting of Varifocal conversion to Fixed Focal Lens

[hotwheels498]

Is there a conversion from the Zoom setting in the EmpireTech varifocal 54 series camera to a Lens MM of a the fixed focal ?

In the camera settings it goes from 26 to 2206.
2.8mm lens = ?
3.6mm lens = ?
6.0 mm lens = ?

You will find there is no real comparison between the focal lengths of these cameras.

Heck even taking the 5442 6mm fixed lens and setting up the 5442-ZE to the equivalent 6mm and you will find the field of view is different for both. The 5442-ZE had to be set to a 9mm equivalent to get the same field of view as the 5442 6mm fixed lens.

You can see a member here demonstrated this thread

The best you can do is kinda take the min and max of the focal length of the camera and assign the 26 to the smaller focal length and the 2206 to the highest and then do interpolation.
