Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for Micro Four Thirds 17.3mm

1 Aperture (f-number) = 2 Equivalent aperture (f-number, DoF basis) · camera-equivalence calculation for Micro Four Thirds 17.3mm

Direct Answer

On Micro Four Thirds 17.3mm, f/5.6 corresponds to about f/11.2 on a full-frame depth-of-field basis

This result uses the fixed Micro Four Thirds 17.3mm sensor profile (crop factor 2).

For 1.4 Aperture (f-number), this corresponds to 2.8 Equivalent aperture (f-number, DoF basis) on Micro Four Thirds 17.3mm.

Explanation

Formula: equivalent_f = f_number x 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.

Aperture (f-number): a camera-equivalence quantity in this family that depends on the selected crop model.

Equivalent aperture (f-number, DoF basis): a camera-equivalence quantity in this family that depends on the selected crop model.

This route is useful when you know the actual lens aperture on Micro Four Thirds 17.3mm and want the full-frame depth-of-field equivalent.

This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Micro Four Thirds 17.3mm).

Method & Sensor Profile

Model basis: Micro Four Thirds 17.3mm sensor profile with crop factor 2 and sensor width 17.3 mm.
Profile reference: Micro Four Thirds 17.3mm (crop factor 2, sensor width 17.3 mm).
Consistency rule: forward and reverse pages keep the same sensor profile; only the formula direction changes.

Frequently Asked Questions

Which sensor assumptions are fixed for aperture f-number to full-frame equivalent f-number?

Aperture f-number to full-frame equivalent f-number is fixed to Micro Four Thirds 17.3mm, crop factor 2, sensor width 17.3 mm.

How do I reverse f to eq f for Micro Four Thirds 17.3mm?

Use the opposite-direction page for Micro Four Thirds 17.3mm to convert equivalent aperture (f-number, dof basis) back to aperture (f-number) with the same sensor assumptions.

Can aperture f-number to full-frame equivalent f-number replace full lens-design simulation?

No. Aperture f-number to full-frame equivalent f-number provides framing and geometry approximations, not full optical-model behavior.

Does equivalent f-number change exposure?

No. Equivalent f-number here is for depth-of-field comparison only. Exposure (light transmission) does not change.
