Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for Full-frame 36mm width (horizontal)
1 Aperture (f-number) = 1 Equivalent aperture (f-number, DoF basis) ยท camera-equivalence calculation for Full-frame 36mm width (horizontal)
Direct Answer
On Full-frame 36mm width (horizontal), f/5.6 corresponds to about f/5.6 on a full-frame depth-of-field basis
This result uses the fixed Full-frame 36mm width (horizontal) sensor profile (crop factor 1).
For 1.4 Aperture (f-number), this corresponds to 1.4 Equivalent aperture (f-number, DoF basis) on Full-frame 36mm width (horizontal).

SwitchExplanation
Formula: equivalent_f = f_number x 1. Why: this page keeps Full-frame 36mm width (horizontal) fixed, so crop factor and sensor width stay explicit for every calculation.
Full-frame 36mm width (horizontal): a sensor profile with crop factor 1 and sensor width (horizontal) 36 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 Full-frame 36mm width (horizontal) 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 (Full-frame 36mm width (horizontal)).

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 Full-frame 36mm width (horizontal), crop factor 1, sensor width 36 mm.
How do I reverse f to eq f for Full-frame 36mm width (horizontal)?
Use the opposite-direction page for Full-frame 36mm width (horizontal) 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.
