Unfortunately you can't vary the input for focal length in your
formulas, which is the whole point to comparing different AOVs of
particular focal lengths on different formats. It's complicated by the
fact that different nominal focal lengths in fisheye lenses give
equivalent results. Just in P
Actually I was going to have it update as you entered numbers in the
focal length box, but it required a bit more exception coding than I was
willing to engage in. I've already found a bug so a new version will be
forthcoming, eventually.
From my research there's no simple formula for fisheye

Yes.
It works fine, but my on quibble is if you select the format size,
then enter the focal length, pressing enter doesn't update the AOV
numbers.
I had to click on the 'compared to' format list (or reset the main
format size), to get the values to update.
Cheers,
Dave.

Same here.

I'll be ready for ya when you do a Java version. ;-)
VB .Net is of no use to Mac OS X users.

I've been doing quite a few stitched panos. Haven't needed more than a
camera and some basic knowledge about
It might be important for understanding to see the numbers, Tom.
Sometimes discussion or other activities moves in a theoretical way.
If you're using several cameras with different format film, sensor,
etc, you might want or need to see numerical values to visualize what

Yeah, I know. Mailing lists are great. I can be generally obnoxious yet
avoid the firsthand repercussions I would get IF I was obnoxious at home.

That's nice if you already own a particular focal length.
Sometimes, however, one might want to have an idea of FoV numerically
for other purposes.
