Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for Super 16 12.5mm
1 Aperture (f-number) = 2.88 Equivalent aperture (f-number, DoF basis) ยท camera-equivalence calculation for Super 16 12.5mm
Direct Answer
On Super 16 12.5mm, f/5.6 corresponds to about f/16.128 on a full-frame depth-of-field basis
This result uses the fixed Super 16 12.5mm sensor profile (crop factor 2.88).
For 1.4 Aperture (f-number), this corresponds to 4.032 Equivalent aperture (f-number, DoF basis) on Super 16 12.5mm.

SwitchExplanation
Formula: equivalent_f = f_number x 2.88. Why: this page keeps Super 16 12.5mm fixed, so crop factor and sensor width stay explicit for every calculation.
Super 16 12.5mm: a sensor profile with crop factor 2.88 and sensor width (horizontal) 12.5 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 Super 16 12.5mm 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 (Super 16 12.5mm).

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 Super 16 12.5mm, crop factor 2.88, sensor width 12.5 mm.
How do I reverse f to eq f for Super 16 12.5mm?
Use the opposite-direction page for Super 16 12.5mm 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.
