Large-circle wide-angle imaging
Very broad coverage over a larger image circle distinguishes MVL-KF0818M-12MP. The 8 mm C-mount lens covers Φ16 mm, identified as 1 inch. Its F1.8 to F11 manual iris is paired with manual focus. Field angles reach 90.06° diagonally, 77.16° horizontally and 61.3° vertically, while distortion is stated at –4.12%. These characteristics place it at the wide end of the large-format KF choices and define the edge geometry for inspection planning.
The 77.16° horizontal field suits large-area presence checks, tray overview and confined installations where the camera must observe a broad scene. The F1.8 opening provides the series' stated large-aperture option, useful when exposure settings call for more light collection, while the iris can be closed to F11 for depth control. Minimum object distance is 0.3 m, a necessary layout constraint for close stations. At Φ56.8 mm × 55 mm and 236 g, the lens also requires more support and clearance than the narrower KF models.
MVL-KF1228M-12MP moves to 12 mm, covers Ø 17.6 mm and narrows the horizontal angle to 59.8°, with F2.8 to F16 adjustment. MVL-KF0814M-12MPE keeps the 8 mm focal length but covers Ø 17.6 mm, opens to F1.4 and provides an 84.8° horizontal field from a 0.1 m minimum object distance. Choose this KF lens for Φ16 mm coverage and a 77.16° view; choose the 12 mm model for tighter framing or the KF-E model for its larger circle and closer focusing limit.

Selection and applications
Large-area presence inspection. Wide tray overview imaging. Confined-space scene capture.
Minimum kit: The basic imaging chain uses a C-mount camera, the MVL-KF0818M-12MP lens, a cable for the selected camera interface, and the electrical supply stated for the camera.
Nearby in the range: MVL-KF1228M-12MP — Prefer it for a tighter 59.8° horizontal view and Ø 17.6 mm image coverage; MVL-KF0814M-12MPE — Prefer it for 8 mm coverage over Ø 17.6 mm with an F1.4 maximum aperture.

FAQ
How wide is the inspection view from the 8 mm KF lens?
The angles are 90.06° diagonal, 77.16° horizontal and 61.3° vertical for the stated Φ16 mm image size. This is the broadest horizontal field among the standard KF entries in the lineup and should be assessed together with its –4.12% distortion.
Which image format and camera mount does MVL-KF0818M-12MP use?
It uses C-mount with a 17.526 mm flange-back length and covers a Φ16 mm image, identified as 1 inch. That image circle is larger than the Ø9 mm coverage of the HF optics, so sensor coverage must be checked independently of the shared C-mount connection.
What does the F1.8 to F11 iris range allow during setup?
The manual iris opens to F1.8 and closes to F11. This provides mechanical control over light collection and depth of field, while manual focus fixes the object plane. Neither setting is motorized, so both are established directly on the lens.
What close-focus and mounting-load limits should be allowed?
Minimum object distance is 0.3 m. The lens measures Φ56.8 mm × 55 mm and weighs 236 g, so the camera mount and bracket must account for that envelope and mass. Its operating range is –10 °C to 50 °C.
How does the KF-E 8 mm alternative change the optical envelope?
MVL-KF0814M-12MPE covers Ø 17.6 mm rather than Φ16 mm, opens to F1.4 rather than F1.8 and focuses from 0.1 m rather than 0.3 m. Its horizontal field is 84.8°, compared with 77.16° for MVL-KF0818M-12MP.
