Lenses for 2/3″ sensors (5–10 MP)
2/3″ is the format of 5–10 MP cameras with larger pixels: at the same resolution the sensor collects more light, so exposure can be shorter and a moving conveyor is captured without blur. Focal lengths from 8 to 75 mm, C-mount. Such a lens also covers smaller formats — 1/1.8″, 1/2″, 1/2.5″ — which is why it is chosen when the camera may still change.

How to choose
These lenses have an 11 mm image circle; a 2/3″ sensor is about 8.5 mm wide (check your camera datasheet for the exact figure). The estimate is the same: f ≈ WD × sensor width / field width, with the exact field taken from the lens FOV table. Watch the minimum object distance: closer than that there is no focus, and an extension ring buys closer focus only at the cost of infinity.
