Questions & answers
Frequently Asked Questions
Which sensor assumptions are fixed for focal length mm to horizontal angle of view (degrees)?
Focal length mm to horizontal angle of view (degrees) is fixed to Drone 1-inch class, crop factor 2.73, sensor width 13.2 mm.
How do I reverse mm to deg for Drone 1-inch class?
Use the opposite-direction page for Drone 1-inch class to convert horizontal angle of view (degrees) back to focal length (mm) with the same sensor assumptions.
Can focal length mm to horizontal angle of view (degrees) replace full lens-design simulation?
No. Focal length mm to horizontal angle of view (degrees) provides framing and geometry approximations, not full optical-model behavior.
