Aperture (f-number) to Equivalent aperture (f-number, DoF basis) for Medium format 44x33
1 Aperture (f-number) = 0.79 Equivalent aperture (f-number, DoF basis) ยท camera-equivalence calculation for Medium format 44x33
Direct Answer
On Medium format 44x33, f/5.6 corresponds to about f/4.424 on a full-frame depth-of-field basis
This result uses the fixed Medium format 44x33 sensor profile (crop factor 0.79).
For 1.4 Aperture (f-number), this corresponds to 1.106 Equivalent aperture (f-number, DoF basis) on Medium format 44x33.

SwitchExplanation
Formula: equivalent_f = f_number x 0.79. Why: this page keeps Medium format 44x33 fixed, so crop factor and sensor width stay explicit for every calculation.
Medium format 44x33: a sensor profile with crop factor 0.79 and sensor width (horizontal) 44 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 Medium format 44x33 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 (Medium format 44x33).

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 Medium format 44x33, crop factor 0.79, sensor width 44 mm.
How do I reverse f to eq f for Medium format 44x33?
Use the opposite-direction page for Medium format 44x33 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.
