FOV translated to lens
-
I have always wondered how the FOV in SU translated to real world lenses. I found this chart and thought I would share. Also, I have read that a 50mm is the closest to the human eye's perception of perspective, so that would mean that a FOV of 46 in SU should be the default, and not 30.

nice! I've been using 45 degrees for the past couple of years so that was quite close!
-
very very intersting sir, thank you for sharing this informations!
any similar table to calculate a phisically correct lens distorsion to match with this? -
You can also type the FOV in mm in the VCB, so no conversion is needed.

learning something new every day!

You know you can just type 50mm in the VCB when you have the Zoom tool active in order to set the focal length?
Nice chart by the way. Good find!
-
Thanks, that is a handy chart for reference.
What site did you find it on?massimo an TT - thanks for the pointer - indeed something new every day

Had absolutely no idea about the mm! Thanks for the tip!!!

To revert back to degrees type "50deg"

Hmm - the FOV for a camera depends on two things: lens length and sensor width. This chart corresponds to Canon cameras - which have their own specific sensor sizes. Does it say if it's APS-C or full frame sensor? Does the SU lens length assume 35mm film?

AFIK - yes. For matching photos from digital cameras (without using PhotoMatch) I've been using conversion tables that convert the digital lens to 35mm and that seem to work.
But note that SU might some times work on the vertical size instead of the horizontal or diagonal size - and it's pretty much impossible to tell.
