Horizontal angle of view (degrees) to Focal length (mm) for Medium format 53.4x40
1 Horizontal angle of view (degrees) = 3,059.516958 Focal length (mm) ยท camera-equivalence calculation for Medium format 53.4x40
Direct Answer
On Medium format 53.4x40, a 50 horizontal angle of view needs about a 57.258335 mm lens
This result uses the fixed Medium format 53.4x40 sensor profile (crop factor 0.67).
To reach 14 Horizontal angle of view (degrees), you need 217.45405 Focal length (mm) on Medium format 53.4x40.

SwitchExplanation
Formula: focal_mm = 53.4 / (2 x tan(HFOV/2)). Why: this page keeps Medium format 53.4x40 fixed, so crop factor and sensor width stay explicit for every calculation.
Medium format 53.4x40: a sensor profile with crop factor 0.67 and sensor width (horizontal) 53.4 mm, used as the fixed framing basis for this page.
Horizontal angle of view (degrees): a camera-equivalence quantity in this family that depends on the selected crop model.
Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.
This route is useful when you know the target horizontal framing angle and need the focal length required on Medium format 53.4x40.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Medium format 53.4x40).

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 Medium format 53.4x40, crop factor 0.67, sensor width 53.4 mm.
How do I reverse deg to mm for Medium format 53.4x40?
Use the opposite-direction page for Medium format 53.4x40 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.
