Tamron M12VM412 overview

  • 1Description

The Tamron C-Mount 4 to 12mm Varifocal Manual Iris Lens is a varifocal lens which features a 4 to 12mm adjustable focal length. Compatible with cameras using a 1/2" imager size and C-mount, the lens is designed to deliver high-quality imagery. With an aperture range of f/1.4 to close, the lens allows for clear images even in low light conditions. The lens surface is multi-coated for lessening ghosting and flare in backlit conditions and eliminates constructional problems such as lopsided blur and focal point image degradation. The integrated slip-mount mechanism allows you to fine-tune the position after mounting the camera to set the auto-iris meter to a proper position around the lens. With the lock for each control ring (zoom and focus), you can avoid setting displacement after installation.

    Tamron M12VM412 reviews

    C-Mount 4 to 12mm Varifocal Manual Iris Lens is rated 4.5 out of 5 by 4.
    Rated 5 out of 5 by from quality for a decent price I use this lens for outdoor filming in an environment containing a lot of water and it gives good results. You will just want to add polarizing film. It produces low physical and color distortion and great images. It also seems pretty solid.

    Rated 5 out of 5 by from Versatile low-light lens with close focus This is the megapixel version of the less expensive IR lens 12VM412ASIR, which is almost as good with as well a slightly lower f/1.2.
    Date published: 2016-01-20
    Rated 4 out of 5 by from the lens is fine but... I cannot fully extend to widest because the back end of the lens hits the camera. I guess it is a 7-12mm I may get an extender ring for it but it looks like it will work for my super 8 camera.

    Rated 4 out of 5 by from it gets the job done Solid lens that does what I expected it to do. Very simple
