Equivalent aperture (f-number, DoF basis) to Aperture (f-number) for Drone 1-inch class
1 Equivalent aperture (f-number, DoF basis) = 0.3663 Aperture (f-number) ยท camera-equivalence calculation for Drone 1-inch class
Direct Answer
On Drone 1-inch class, a full-frame equivalent aperture of f/5.6 needs about f/2.051282
This result uses the fixed Drone 1-inch class sensor profile (crop factor 2.73).
To match 1.4 Equivalent aperture (f-number, DoF basis), you need 0.512821 Aperture (f-number) on Drone 1-inch class.

SwitchExplanation
Formula: f_number = equivalent_f / 2.73. Why: this page keeps Drone 1-inch class fixed, so crop factor and sensor width stay explicit for every calculation.
Drone 1-inch class: a sensor profile with crop factor 2.73 and sensor width (horizontal) 13.2 mm, used as the fixed framing basis for this page.
Equivalent aperture (f-number, DoF basis): a camera-equivalence quantity in this family that depends on the selected crop model.
Aperture (f-number): a camera-equivalence quantity in this family that depends on the selected crop model.
This route is useful when you know the full-frame depth-of-field equivalent and need the actual aperture on Drone 1-inch class.
This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Drone 1-inch class).

Frequently Asked Questions
Which sensor assumptions are fixed for full-frame equivalent f-number to aperture f-number?
Full-frame equivalent f-number to aperture f-number is fixed to Drone 1-inch class, crop factor 2.73, sensor width 13.2 mm.
How do I reverse eq f to f for Drone 1-inch class?
Use the opposite-direction page for Drone 1-inch class to convert aperture (f-number) back to equivalent aperture (f-number, dof basis) with the same sensor assumptions.
Can full-frame equivalent f-number to aperture f-number replace full lens-design simulation?
No. Full-frame equivalent f-number to aperture 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.
