Engineering data
Field of view with the LS-SWL-0142
Worked out from this lens's own focal length, image circle and closest focus: what it sees at your working distance, on the sensor you use.
| Sensor format | At 5000 mm |
|---|---|
| 1/3"4.8 × 3.6 mm | 480 × 360 mm |
| 1/2.9"4.98 × 3.74 mm | 498 × 374 mm |
| 1/2"6.4 × 4.8 mm | 640 × 480 mm |
Thin-lens approximation: field of view ≈ sensor size × working distance ÷ focal length, with the distance measured to the front of the lens; closest to reality when the distance is many times the focal length. Sensor sizes are typical for each optical format.
