Fast wide-angle KF-E coverage
An F1.4 opening and an 8 mm focal length make MVL-KF0814M-12MPE the fast, wide-angle KF-E choice. The C-mount lens covers a Ø 17.6 mm, 1.1-inch image with 98.4° diagonal, 84.8° horizontal and 68° vertical fields. Focus and iris are manual, and the aperture closes to F16. Distortion is stated at 5.5%, an important quantified characteristic when the broad view includes geometry near the edge of the image.
The 84.8° horizontal field supports large-area inspection, close machine overviews and multiple-object presence checks where mounting distance is restricted. A 0.1 m minimum object distance allows close placement, and F1.4 supplies the largest listed opening among the KF and KF-E models in the lineup. Manual iris adjustment toward F16 can extend depth coverage when light permits. The Ø 60 mm × 77.8 mm body weighs 371 g, so the camera bracket must accommodate both the wide barrel and its load.
MVL-KF0818M-12MP also uses 8 mm but covers Φ16 mm, opens to F1.8, gives a 77.16° horizontal field and focuses from 0.3 m. MVL-KF1628M-12MPE retains the Ø 17.6 mm KF-E image circle while narrowing coverage to 45.8° at 16 mm and opening to F2.8. Choose this model for the combined 84.8° view, F1.4 aperture and 0.1 m focusing limit; choose the KF model for its smaller circle or the 16 mm KF-E lens for tighter framing.

Selection and applications
Very-wide machine overview. Close large-area inspection. Multiple-object presence checks.
Minimum kit: A complete starting chain consists of a C-mount camera, the MVL-KF0814M-12MPE lens, that camera's interface cable, and the power arrangement defined for the camera.
Nearby in the range: MVL-KF0818M-12MP — Prefer it for 8 mm imaging over Φ16 mm with an F1.8 maximum aperture; MVL-KF1628M-12MPE — Prefer it when a 16 mm focal length and 45.8° horizontal field give tighter framing.

FAQ
How broad is the inspection image from the 8 mm KF-E lens?
The stated fields are 98.4° diagonal, 84.8° horizontal and 68° vertical over a Ø 17.6 mm image. That coverage is broader than the 8 mm standard KF model's 77.16° horizontal angle and is accompanied by a 5.5% distortion figure.
What does the F1.4 maximum aperture contribute to setup?
The manual iris ranges from F1.4 to F16. Opening to F1.4 increases light collection, while closing the iris can increase depth of field when illumination permits. Focus is also manual, so exposure depth and the object plane are established mechanically.
Which camera format and mount match MVL-KF0814M-12MPE?
The lens uses C-mount with a 17.526 mm flange-back length and covers a Ø 17.6 mm image, identified as 1.1 inch. Its 8 mm focal length supplies the wide field, while the camera sensor must remain within the stated image circle.
What close-focus, size and weight constraints apply?
Minimum object distance is 0.1 m. The housing measures Ø 60 mm × 77.8 mm and weighs 371 g, making it the largest load among the KF and KF-E entries here. The operating range is –10 °C to 50 °C.
How does the standard 8 mm KF model differ from this KF-E lens?
MVL-KF0818M-12MP covers Φ16 mm, opens to F1.8 and focuses from 0.3 m. This KF-E lens covers Ø 17.6 mm, opens to F1.4 and focuses from 0.1 m. Horizontal angles are 77.16° and 84.8° respectively.
