SwitchExplanation
Formula: focal_mm = equivalent_mm / 0.67. 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.
35mm equivalent focal length (mm): 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 full-frame equivalent focal length and need the actual lens focal length 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 full-frame equivalent mm to focal length mm?
Full-frame equivalent mm to focal length mm is fixed to Medium format 53.4x40, crop factor 0.67, sensor width 53.4 mm.
How do I reverse eq mm to mm for Medium format 53.4x40?
Use the opposite-direction page for Medium format 53.4x40 to convert focal length (mm) back to 35mm equivalent focal length (mm) with the same sensor assumptions.
Can full-frame equivalent mm to focal length mm replace full lens-design simulation?
No. Full-frame equivalent mm to focal length mm provides framing and geometry approximations, not full optical-model behavior.
