Field of view (width × height) of the 75 mm lens by sensor format and working distance
Sensor formatAt 10000 mm
1/2"6.4 × 4.8 mm853 × 640 mm
1/1.8"7.07 × 5.3 mm943 × 707 mm
2/3"8.45 × 7.07 mm1127 × 943 mm
1/1.2"11.25 × 7.03 mm1500 × 937 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.
