35mm equivalent focal length (mm) to Focal length (mm) for Smartphone 1/2.55" class
1 35mm equivalent focal length (mm) = 0.166667 Focal length (mm) ยท camera-equivalence calculation for Smartphone 1/2.55" class
Direct Answer
On Smartphone 1/2.55" class, a 50 mm full-frame equivalent needs about a 8.333333 mm lens
This result uses the fixed Smartphone 1/2.55" class sensor profile (crop factor 6).
To match 14 35mm equivalent focal length (mm), you need 2.333333 Focal length (mm) on Smartphone 1/2.55" class.

SwitchExplanation
Formula: focal_mm = equivalent_mm / 6. Why: this page keeps Smartphone 1/2.55" class fixed, so crop factor and sensor width stay explicit for every calculation.
Smartphone 1/2.55" class: a sensor profile with crop factor 6 and sensor width (horizontal) 6 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 Smartphone 1/2.55" class.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Smartphone 1/2.55" class).

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 Smartphone 1/2.55" class, crop factor 6, sensor width 6 mm.
How do I reverse eq mm to mm for Smartphone 1/2.55" class?
Use the opposite-direction page for Smartphone 1/2.55" class 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.
