Questions & answers
Frequently Asked Questions
Which sensor assumptions are fixed for horizontal angle of view (degrees) to focal length mm?
Horizontal angle of view (degrees) to focal length mm is fixed to APS-C Canon 22.3mm, crop factor 1.6, sensor width 22.3 mm.
How do I reverse deg to mm for APS-C Canon 22.3mm?
Use the opposite-direction page for APS-C Canon 22.3mm to convert focal length (mm) back to horizontal angle of view (degrees) with the same sensor assumptions.
Can horizontal angle of view (degrees) to focal length mm replace full lens-design simulation?
No. Horizontal angle of view (degrees) to focal length mm provides framing and geometry approximations, not full optical-model behavior.
