Focal length (mm) to 35mm equivalent focal length (mm) for Compact 1/2.5" class
1 Focal length (mm) = 6.8 35mm equivalent focal length (mm) ยท camera-equivalence calculation for Compact 1/2.5" class
Direct Answer
On Compact 1/2.5" class, a 50 mm lens gives about a 340 mm full-frame equivalent
This result uses the fixed Compact 1/2.5" class sensor profile (crop factor 6.8).
For 14 Focal length (mm), this corresponds to 95.2 35mm equivalent focal length (mm) on Compact 1/2.5" class.

6.8 35mm equivalent focal length (mm)
SwitchExplanation
Formula: equivalent_mm = focal_mm x 6.8. Why: this page keeps Compact 1/2.5" class fixed, so crop factor and sensor width stay explicit for every calculation.
Compact 1/2.5" class: a sensor profile with crop factor 6.8 and sensor width (horizontal) 5.76 mm, used as the fixed framing basis for this page.
Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.
35mm equivalent 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 actual lens focal length on Compact 1/2.5" class and want the matching full-frame equivalent framing reference.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Compact 1/2.5" class).

Frequently Asked Questions
Which sensor assumptions are fixed for focal length mm to full-frame equivalent mm?
Focal length mm to full-frame equivalent mm is fixed to Compact 1/2.5" class, crop factor 6.8, sensor width 5.76 mm.
How do I reverse mm to eq mm for Compact 1/2.5" class?
Use the opposite-direction page for Compact 1/2.5" class to convert 35mm equivalent focal length (mm) back to focal length (mm) with the same sensor assumptions.
Can focal length mm to full-frame equivalent mm replace full lens-design simulation?
No. Focal length mm to full-frame equivalent mm provides framing and geometry approximations, not full optical-model behavior.
