Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for Compact 1/2.5" class
1 Aperture (f-number) = 6.8 Equivalent aperture (f-number, DoF basis) ยท camera-equivalence calculation for Compact 1/2.5" class
Direct Answer
On Compact 1/2.5" class, f/5.6 corresponds to about f/38.08 on a full-frame depth-of-field basis
This result uses the fixed Compact 1/2.5" class sensor profile (crop factor 6.8).
For 1.4 Aperture (f-number), this corresponds to 9.52 Equivalent aperture (f-number, DoF basis) on Compact 1/2.5" class.

6.8 Equivalent aperture (f-number, DoF basis)
SwitchExplanation
Formula: equivalent_f = f_number 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.
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 Compact 1/2.5" class 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 (Compact 1/2.5" class).

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 Compact 1/2.5" class, crop factor 6.8, sensor width 5.76 mm.
How do I reverse f to eq f for Compact 1/2.5" class?
Use the opposite-direction page for Compact 1/2.5" class 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.
