What the V-5500 lens is

The Marshall Electronics V-5500 is a 1/2" 5MP M12-mount lens with a 3.9mm focal length and f/2 aperture. It is built for visible and IR-corrected imaging, making it suitable for day-and-night surveillance, machine vision, broadcasting and medical camera systems. High-quality glass optics sit in an anodised aluminium housing and the lens meets RoHS environmental standards.

Who this suits and who should look elsewhere

The lens suits integrators and engineers who need an M12-mount optic that delivers sharp, low-distortion images across a 1/2" sensor at 5MP resolution. It is not for buyers whose cameras use a larger sensor format, a different mount thread, or who require a longer focal length for narrow-field viewing. It also does not address applications demanding motorised zoom or auto-iris control.

Behaviour under sustained load

The MTF exceeds 70% at the centre field and 63% at the full field, indicating consistent sharpness from centre to corner during continuous operation. The all-glass, anodised-aluminium construction resists thermal drift and maintains focus stability over long recording sessions. IR correction keeps focus aligned when illumination shifts between visible and near-infrared without manual readjustment.

Highlights

  • Sharp 5MP resolution from 1/2" optical design
  • Clear imaging day and night with IR correction

Questions about this item

What camera mount do I already need to use the V-5500 lens?

The lens fits an M12 mount, so your camera body must provide a matching M12 thread for it to attach.

Will the 3.9mm focal length cover the same view as my older 6mm lens?

The 3.9mm focal length gives a wider field of view than a 6mm lens, so you will see more of the scene from the same position.

How can I confirm the lens is resolving the full 5MP after installation?

Check that centre MTF exceeds 70% and full-field MTF exceeds 63%; sharp, low-distortion corners across the frame indicate correct performance.
