  • Our take on the 191° Fisheye Lens S-Mount for 10-12MP Sensors

    The CIL281 is a 1.95mm M12-mount fisheye lens built for 10-12MP sensors. It projects a 200° field over a 6.4mm image circle, and its F/1.8 aperture lets in more light than the slower F/2.0-F/2.8 fisheyes common at this size. It suits surveillance and robotics builders who need a near-hemispherical view from a small board camera. The trade-off is heavy barrel distortion and soft corners, which is normal for this class of lens.

    Pros
    • 200° field of view over a 6.4mm image circle
    • Fast F/1.8 aperture for low-light capture
    • Ingress protection for outdoor and industrial use
    • M12 S-mount fits common board cameras
    • Resolves 10-12MP sensors
    Cons
    • Strong barrel distortion, unusable for rectilinear work
    • Corners are soft at the edges of the circle
    • Manual focus only, no autofocus or electronics
    • Needs a sensor sized to the 6.4mm image circle

    Questions and answers

    What sensor size does this lens cover?
    It is specified for a 6.4mm image circle, so it pairs with small sensors in the 10-12MP range. Larger sensors will vignette or crop the fisheye circle.
    Is it autofocus?
    No. It is a manual-focus M12 lens, so you set focus by turning the barrel and locking it in place.
    Can I use it indoors in low light?
    Yes. The F/1.8 aperture gathers more light than slower fisheyes, which helps in dim rooms and at dusk.
    Is it weatherproof?
    The lens is described as ingress protected, so it can handle outdoor and industrial environments. The camera housing still needs its own sealing.
    What mount does it use?
    It uses an M12 S-mount thread, the standard for small board cameras and many machine-vision modules.
    Will it give straight lines?
    No. It is a fisheye, so straight lines bow heavily. You need software dewarping if you want a rectilinear image.
