Creator: Vlado Damjanovski | Computers - 2013-09-23

Theoretically, it is better to know the lens characteristics for a continuous variation of black to white (in the form of a sine wave), and not just for stripes that abruptly change from black to white. This would be especially suitable for TV lenses ...

    Nice wide-angle image... although there was some initial concern

    I purchased two of these 2.1mm extra wide-angle lenses to substitute on two cameras originally having the "standard" 3.6mm lenses, so that I could get full views of areas approximately 16' x 20', when viewed from a camera site on the ceiling at one end of each area. (The narrower field of view of the standard lenses did not permit full view of these "tight" areas). These 2.1mm lenses work great in both cases, giving a nearly complete view of these areas. The views are clear and sharp, although naturally give the "fish-bowl" distortion of a wide-angle lens. The lenses allow great images, both in daylight (color mode), and under 850nm IR illumination (b/w mode, during low-light conditions). I am very pleased with the images provided by these lenses.The only concern that I had was when I was installing one of the lenses (while the camera was "live"): I noticed a couple small specks of dirt or debris - or *possibly* even chinks in the lens... 5/5 TechnoJunkie - See all my reviews This review is from: Wide Angle 2.1mm 1080P Board Lens Black for Security Camera CCTV Surveillance (Electronics) I purchased two of these 2.1mm extra wide-angle lenses to substitute on two cameras originally having the "standard" 3.6mm lenses, so that I could get full views of areas approximately 16' x 20', when viewed from a camera site on the ceiling at one end of each area.

    Great Deal

    5/5 alan - See all my reviews Verified Purchase(What's this?) This review is from: 6-15mm 1/3" F1.4 CS Mount Varifocal CCTV Manual Lens (Electronics) This lens is a great deal. With its manual zoom, focus, and aperture settings, it is perfect for the IP video camera I occasionally use to keep an eye out for visitors while I'm doing things in other places. This lens is a HUGE improvement over the fixed focal-length, fixed aperture lens that came with my video camera, and for the the price, it's a steal. It was shipped from Hong Kong, but the delivery time, considering, was surprisingly fast. Help other customers find the most helpful reviews  Was this review helpful to you? , November 28, 2012

    All "Fixed Iris Lenses" are normally used in constant lighting conditions, such as indoors.
    As lens focal length increases, the field of view narrows and distant objects are more define.
    Monofocal Fixed Iris Lenses are commonly used for doom and cameras.
    These lenses are factory set for a fixed focal length to achieve the optimal field of view.
    This type of fixed iris lenses with fixed focal length are the least expensive and most commonly used in CCTV cameras.
