Where'd 41.4214 come from?

If aperture is camx width in mm then I’m totally confused about where 41.4214 comes from??

Any ideas?

Thanks much,

Combined with the default focal length of 50, this gives you a horizontal field of view of 45 degrees. See in the online help:

cool, thanks

Wasn't sure why that number was used but if 45deg. was the target fov with default settings and 50mm I can understand that.

Thanks,
