Redmoon Converters Convert focal length and aperture between Full Frame, APS-C Canon (1.6x), Sony/Nikon APS-C (1.5x), Micro Four Thirds, 1-inch, Fuji GFX and Phase One sensors.
| Sensor | Crop | Equivalent focal (mm) | Equivalent aperture (DOF) |
|---|
Field of view scales with the crop factor: equivalent focal = focal × (source crop / target crop). Depth of field scales the same way: equivalent aperture = aperture × (source crop / target crop). Exposure is unchanged — an f/2.8 lens still meters at f/2.8 on any sensor.
Crop factors are relative to a 36×24 mm full-frame sensor (diagonal ≈ 43.27 mm).
