Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for 1-inch sensor 13.2mm
1 Aperture (f-number) = 2.73 Equivalent aperture (f-number, DoF basis) ยท camera-equivalence calculation for 1-inch sensor 13.2mm
Direct Answer
On 1-inch sensor 13.2mm, f/5.6 corresponds to about f/15.288 on a full-frame depth-of-field basis
This result uses the fixed 1-inch sensor 13.2mm sensor profile (crop factor 2.73).
For 1.4 Aperture (f-number), this corresponds to 3.822 Equivalent aperture (f-number, DoF basis) on 1-inch sensor 13.2mm.

SwitchExplanation
Formula: equivalent_f = f_number x 2.73. Why: this page keeps 1-inch sensor 13.2mm fixed, so crop factor and sensor width stay explicit for every calculation.
1-inch sensor 13.2mm: a sensor profile with crop factor 2.73 and sensor width (horizontal) 13.2 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 1-inch sensor 13.2mm 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 (1-inch sensor 13.2mm).

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 1-inch sensor 13.2mm, crop factor 2.73, sensor width 13.2 mm.
How do I reverse f to eq f for 1-inch sensor 13.2mm?
Use the opposite-direction page for 1-inch sensor 13.2mm 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.
