Compact S-mount (M12) lenses

The M12 thread (S-mount) covers optics for embedded cameras and code readers where space is measured in millimetres. Focal lengths from 3.37 to 25 mm: short ones give a wide angle for close-up work, longer ones keep a normal field of view inside a tight housing.

How to choose

S-mount focusing is done by turning the lens in its thread, so after setup it is locked with a nut — otherwise vibration will drift the focus. Wide-angle versions show more distortion than longer ones, but the actual figure is given per part number — check it if you measure from the image.

FAQ

What should be checked before choosing an M12 focal length?

Set the required field of view and object distance first. The family spans 3.37 to 25 mm: shorter options give a wider angle for close-up work, while longer options give a narrower view. Then verify coverage, aperture and focus range.

How are the F2.8 and F5.6 groups arranged?

F2.8 is listed at 3.37, 6, 8, 12, 16 and 25 mm. F5.6 alternatives appear at 8, 12, 16 and 25 mm. At a shared focal length, use the model designation to keep aperture, image-circle diameter and focusing limits aligned.

Which lens in the family focuses to infinity?

MVL-HF0856-05S is the listed 8 mm, F5.6 version with a focus range from 100 mm to infinity. The other models show finite upper limits, ranging from 850 to 950 mm, so this focus-range distinction should be checked explicitly.

Why is the locking nut important after focusing?

An S-mount lens is focused by turning it in the M12 thread. The selected position is then held with a nut; otherwise vibration can shift the focus. Set focus at the intended object distance and lock the thread after the adjustment.

When does lens distortion need extra attention?

The wide-angle versions show more distortion than the longer lenses. This is particularly relevant when dimensions will be taken from the image. Check the value associated with the chosen part number rather than assuming one figure for every focal length.
