35mm equivalent focal length (mm) to Focal length (mm) for Micro Four Thirds 17.3mm
Snapshot
On Micro Four Thirds 17.3mm, a 50 mm full-frame equivalent needs about a 25 mm lens. Conversion Encyclopedia keeps the same sensor profile across the calculator, common values, and reverse page for this page.
- Sensor profile: Micro Four Thirds 17.3mm (17.3 mm width, crop factor 2).
- Example: To match 14 35mm equivalent focal length (mm), you need 7 Focal length (mm) on Micro Four Thirds 17.3mm.
- Use the reverse page if you need the opposite direction with the same basis.

SwitchExplanation
Formula: focal_mm = equivalent_mm / 2. Why: this page keeps Micro Four Thirds 17.3mm fixed, so crop factor and sensor width stay explicit for every calculation.
Micro Four Thirds 17.3mm: a sensor profile with crop factor 2 and sensor width (horizontal) 17.3 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 Micro Four Thirds 17.3mm.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Micro Four Thirds 17.3mm).

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 Micro Four Thirds 17.3mm, crop factor 2, sensor width 17.3 mm.
How do I reverse eq mm to mm for Micro Four Thirds 17.3mm?
Use the opposite-direction page for Micro Four Thirds 17.3mm 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.
