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.
