CCTV, From Light to Pixels

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 Telephoto lens for many cameras

    4/5 pat Photo, video, computer geek - See all my reviews Verified Purchase(What's this?) This review is from: uxcell Replacement Black CCTV Box Camera 25mm Focal Length Board Lens F1.2 (Camera) Compared to the usual approx. 3mm lens on security cameras, this is about an 8x telephoto. The lens mount is a "standard" M-12 (The diameter of the mount is 12 mm - just under 1/2 inch) as is used on most low resolution cameras. With an 8x telephoto, you'll have to carefully focus this by screwing the lens in for longer distances and out for shorter distances. I don't know for sure, but I suspect this is not "megapixel" sharpness. I installed mine on an APEXIS pan and tilt 640x480 camera to pick up license plates on my driveway and mailbox.The attached photo was taken at 9 PM May 22 (somewhat dark outside with a street light 120 ft away). The mailbox is about 40 feet from the camera. (The black square on the back of the mailbox gets covered by the white rectangle when the mailbox is opened, triggering motion detection), May 22, 2016

This review is from: uxcell Replacement Black CCTV Box Camera 25mm Focal Length Board Lens F1.2 (Camera) Used on a Costco/ Lorex LHV828/ LHV2000 security system. CAUTION ... The lens is too long for the camera to close by 1/2 inch. Camera is the LBV2521. Stock is 3.6mm for 4 to 25 ft focus. This 25mm focuses for 80 to 100 ft. Install is easy and focus is adjusted by screw in or out. CAUTION ... The lens is too long for the camera to close by 1/2 inch. We sealed with metal tape to get the excellent zooming.

    Very Nice 25mm Miniature Camera Lense

    It says it's for box cctv cameras, however I used mine on a mini ip board camera without any problems. Usually the back focus is a problem when buying some long focus lenses, but in this case for my use I didn't have any problems getting it into focus on my mini ip board camera. The image quality is clear and it works well for my hobby purposes of having the tiny board camera sitting in a window looking at a hummingbird feeder just outside of the window in our yard this past fall for hummingbird migration (2016).For other cameras I couldn't say how well it will work, because sometimes you don't have enough back focus on longer focus lenses - however - if you're a hobbyist with access to a mini mill like I have you can always shave 2-3mm off of your camera's screw in lens mount and achieve back focus properly. WARNING - That's a hobbyists tip and not any thing I'd recommend for anyone who has back focus problems unless if you are extremely handy with the right tools and... 5/5 Amazon Customer - See all my reviews Verified Purchase(What's this?)

    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.

    Far Exceeded Expectations Considering Price

    5/5 MattBianco - See all my reviews Verified Purchase(What's this?) This review is from: Fotasy M3517 35MM F1.7 TV Movie Fixed Lens and Lens Adapter Kit for Olympus Panasonic MFT Micro 4/3 M43 Cameras (Electronics) I am not a photographer and I wanted a lens for low light situations for my Panasonic GX7, without spending a lot of money as I have minimal use for low light photography or videos. The lens (35mm version) exceeded my expectations. I also bought a 25mm version without the adapter (different amazon listing) and have provided sample photos of that lens in that review as well.Both lenses perform well. The 35mm does not vignette at all. The 25mm does at higher F settings.Also:• The adapter fit perfectly• No problems with zooming to infinityCon:• Lens does not have a coating or a good enough coating as in some photos you may get a bright spot when pointed not directly at, but near a bright light source.• Focus ring is smooth, but at times it gets jammed near infinity, December 15, 2014

    I love it on my Panasonic Lumix G7

    I found out about this lens by accident when researching about anamorphic lenses for my Panasonic Lumix G7. I was looking for a lens which would give videos a different look, maybe more of a "film" look. A couple of things which I found odd (at first) was the price and it stating it's a CCTV camera lens. Upon reading other reviews on other sites and watching video samples on YouTube I decided to give it a try. It's not an expensive $400+ anamorphic lens but hard to beat for a unique lens for under $30 (at time of purchase).The lens was delivered via USPS inside a small bubble padded envelope. Inside the envelope was a small white box which contained the lens and the adapter to allow it to fit a micro four thirds body. I was surprised by the weight. The lens is made of metal and feels durable. At the front of the lens there's a ring which is almost half an inch in height and kind of works as a lens hood even though lens flares are still seen at specific angles.

    Makes you work for it, but you get some interesting shots.

    4/5 Eric - See all my reviews Verified Purchase(What's this?) This review is from: Fotasy M2514 25MM F1.4 TV Movie Lens and Lens Adapter Kit for Olympus Panasonic MFT Micro 4/3 M43 Cameras (Electronics) This lens will make you work for the results, but you get interesting character in your shots that you don't get in other lenses. This won't replace any of your walk around lenses, but when you want some unique bokeh on a budget, this is where it's at.Although this is a cinema / TV lens, it is VERY jittery if you don't have some sort of in body stabilization on your camera. I suggest using a tripod to get the best results.I've included a sample picture to give you an idea of the look and feel of this lens. You'll notice that on the left side, the chair arm is more in focus than the right side, even though they are both equal distance away from the camera. These are the kinds of weird results this lens produces, and you either love it or hate it. I wouldn't be able to recreate this shot if I tried, even using the same lens.At the end of the day: it's a cheap, fun lens. So get it and enjoy!, February 9, 2017
