Field of view & crop factor calculator
Angle of view of a lens on your sensor, its full-frame (or any format) equivalent and how much of the scene fits in the frame.

Same framing on every format
| Format | Crop | Focal length | Aperture (same DoF) |
|---|---|---|---|
| Medium format 54×40 | 0.65× | 83 mm | f/4.3 |
| Medium format 44×33 | 0.79× | 68 mm | f/3.5 |
| Full frame | 1× | 54 mm | f/2.8 |
| APS-C (Sony, Nikon, Fuji) | 1.53× | 35 mm | f/1.8 |
| APS-C Canon | 1.61× | 33 mm | f/1.7 |
| Micro Four Thirds | 2× | 27 mm | f/1.4 |
| 1-inch | 2.73× | 20 mm | f/1 |
Crop factor = full-frame diagonal ÷ sensor diagonal. The equivalent aperture gives the same depth of field and background blur at the same framing; exposure (shutter speed, ISO) stays the same f-number. Sensor sizes are typical for each format and differ slightly between cameras.
