Full Frame sensor size
Full frame matches the frame size of classic 35 mm film. It is the reference format for crop factor and focal-length equivalence: a lens on full frame gives exactly the field of view its focal length implies.
Also called: 35mm format, FX (Nikon), 135 format

Full-frame equivalent focal lengths on Full Frame
What common lenses frame like when mounted on Full Frame. Field of view is computed from this sensor's actual width and diagonal.
| Lens | Full-frame equivalent | Horizontal FoV | Diagonal FoV |
|---|---|---|---|
| 14 mm | 14.0 mm | 104.3° | 114.2° |
| 24 mm | 24.0 mm | 73.7° | 84.1° |
| 35 mm | 35.0 mm | 54.4° | 63.4° |
| 50 mm | 50.0 mm | 39.6° | 46.8° |
| 85 mm | 85.0 mm | 23.9° | 28.6° |
| 135 mm | 135.0 mm | 15.2° | 18.2° |
| 200 mm | 200.0 mm | 10.3° | 12.3° |
Lens needed on other formats for the same view
To reproduce a full-frame framing on another format, divide the full-frame focal length by that format's crop factor.
| Format | for 24 mm FF | for 50 mm FF | for 85 mm FF |
|---|---|---|---|
| APS-C (Sony, Nikon, Fujifilm) | 15.7 | 32.8 | 55.7 |
| APS-C (Canon) | 14.9 | 31.0 | 52.7 |
| Micro Four Thirds | 12.0 | 25.0 | 42.5 |
| 1-inch | 8.8 | 18.3 | 31.2 |
| Medium Format 44×33 | 30.4 | 63.3 | 107.6 |
| APS-H | 18.6 | 38.7 | 65.9 |
