APS-C (Canon) sensor size
Canon's APS-C sensor is smaller than the Sony, Nikon and Fujifilm version, which is why Canon quotes a 1.6× crop instead of 1.5×. The same lens therefore frames tighter on a Canon APS-C body.
Also called: Canon APS-C, Canon EF-S, Canon RF-S

Lens needed on Canon APS-C to match a full-frame view
Divide a full-frame focal length by 1.61× to find the lens that gives the same view on Canon APS-C. Real lenses come in fixed focal lengths, so pick the nearest one available.
| Full-frame view | Focal length on Canon APS-C |
|---|---|
| 14 mm on full frame | 8.7 mm |
| 24 mm on full frame | 14.9 mm |
| 35 mm on full frame | 21.7 mm |
| 50 mm on full frame | 31.0 mm |
| 85 mm on full frame | 52.7 mm |
| 135 mm on full frame | 83.7 mm |
| 200 mm on full frame | 124.0 mm |
