FAQs

1. What is the field of view (FoV) for a 2.8mm M12 lens?

The FoV depends on the sensor size. For a 1/2.7” sensor, the horizontal FoV is approximately 110°, making it ideal for wide-angle applications.

2. Can M12 lenses be used in low-light conditions?

Yes. Towin’s M12 lenses feature apertures as wide as F2.0, allowing sufficient light intake for dim environments. Pairing them with low-light sensors enhances performance further.

3. Are M12 lenses compatible with all cameras?

M12 lenses are compatible with cameras using an M12 (S-mount) thread. Ensure the lens’s image circle matches your sensor size (e.g., 1/3” or 1/2.7”).

4. How do M12 lenses compare to C-mount lenses?

M12 lenses are smaller, lighter, and more cost-effective, making them suitable for compact devices. C-mount lenses offer larger image circles but are bulkier.
