Designed for 24-hour operation the Tamron 12VM412ASIR uses infrared corrected lens elements to produce brighter images in lighting conditions ranging from ambient to totally dark locations and is compatible with both Day/Night and conventional B/W cameras. Using special multi-layer lens coating, this vari-focal lens provides corner-to-corner image quality and compensates for glare and ghosting caused by back-lit environments.

IR

Uses advanced infrared optical elements to produce brighter images in both regular and near total dark conditions and is ideal for use with both Day/Night and conventional B/W cameras.

Vari-Focal

Uses an advanced aspherical multi-coated lens design to provide vari-focal versatility in near and far image viewing and to boost corner resolution when used with digital cameras.

Features a focus and iris ring lock mechanism to prevent shifting when used on vibrating equipment.

Slip Mount

Enables lens rotation after camera mounting, allowing an accurate iris reading based on the camera's position.

question

Does this lens take infrared picture or normal images? (I have seen review of this lens that takes normal images. is there a non infrared version of the lens?)
Asked by: Anonymous
This lens records both infrared and normal wavelengths of light.Most lenses are not corrected for infrared light.Which means if you set the focus on your lens for normal shooting it will be blurred or out of focus for shooting infrared.If you likewise set the focus for infrared and try and shoot the next day in daylight it will be out of focus again.This because infrared light focuses at different points in the lens than all the other wavelengths of light.What THIS lens does is it keeps you from having to refocus everytime you switch from shooting in normal light to nighttime infrared aided light.This is done using a IR coating to make sure the the wavelengths of light focus on the same point in the lens barrel no matter if its IR or not.Hope that helps anserw your question.23

question

Is this IR Filter lens?
Asked by: Dhananjay Y.
No, it's the opposite -- it lets IR light through rather than filtering it off.
