Poser cameras: Just the math, untested

This is based on the idea that the lens size really is 25mm, as well as the default focal being that, and that using of this the human eye ration comes out pretty close to 50mm, as you can see, which would seem to ratify this. However, it seems to me that the 14mm focal to simulate an SLR sounds pretty low, and I'm wondering why they wouldn't go with a 50mm lens to make the focal numbers more familiar to SLR users, who are the only people besides professional photographers (motion or still) that really pay much attention to these things.
