    First let me start by saying that every lens has it's purpose. This lens is meant to be used for portraits and or close up photography.For $28 this is hands down amazingly worth the buy! I just got it in the mail a few hours ago but the moment I opened the box I knew I was satisfied with my buy. I thought it's plastic but it's metal, solid and has weight to it. The image quality is definitely sharp enough. Unless your magnifying the image by 300% or more the sharpness is perfect. I've purchased this for my NEX-5N and it fits as should, tight and no wobble. I'm very happy I decided to buy this.I recommend this for anyone looking for $300 lens capability at 1/10 the price. I'm putting the 50mm 1.4 they make on order right now, I can't wait!UPDATEPictures only have adjustments made to crop, contrast, saturation, ambiance, warmth, and vignette.

    For the price, a must-have

    If you're on a budget and you don't own a 35mm prime lens, this little lens is a must-have!

My DSLR prime lenses are like 3x bulkierIDEAL AMBIANCE: Simply because you have to manually adjust the focus, I wouldn't recommend this for shooting moving subjects. It's best suited for still photography (i.e. portraits, still life) where you have all the time in the world to fine-tune. A monopod or tripod would be beneficial. If shooting a few feet away or closer, you'd ideally only care about one specific area of the subject in focus (i.e. a few petals from a large flower). The focus ring is by no means *difficult* to operate or unsmooth, but it does require you to exert more force than say, manually focusing on an EF-S lens.BUILD QUALITY: The lens itself is VERY solid--all metal/glass except for... 5/5 tightsandtea - See all my reviews Verified Purchase(What's this?)

    Really Nice 16mm Lens

    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 several of my mini ip board cameras. The image quality is clear and it works well for my hobby purposes of having tiny board cameras sitting in a window looking at hummingbird feeders just outside of the window in our yard this past fall for hummingbird migration (2016). I then fed the live streams to our big screen tv and kicked back and we watched them do all sorts of fun flying and territorial sparring.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.

    Zoom for Lorex

    5/5 James M - See all my reviews Verified Purchase(What's this?) This review is from: uxcell CCTV Security Camera 1/3" F2.0 16mm Focus Length 21 Angle Fixed IR Board Lens (Electronics) Zoom for the Lorex system LHV828 camera LBV2521.No need for another camera now. This lens worked for 80 to 100 ft person ID! With 16mm it gives about a 4x zoom on this system and camera. It could read a license plate in daylight at 100 ft and a person filled half of the screen height. Just remove the glue with a drop of carb cleaner, screw out the old lens and screw in the new one until you get focus. I also ordered 12mm and 25mm to experiment more. That 12*.05mm thread is a key requirement for this camera.Jim Help other customers find the most helpful reviews  Was this review helpful to you? , July 18, 2015

    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.

    I am not a photographer, but like taking pictures.Pros:- crips pictures, with a center that is well focused, and permitter more out of focus when F is closer to 1.4- very bright in low light. You can take pictures with just a candle light- affordable for anyone who wants a fun lens- produces very soft bokeh (sp?), especially for a lens of its price- with an adapter worked flawlessly on my Micro 4/3 Panasonic GX7Cons:- the ring to set the F is closer to the front of the lens where you would expect focus to be, and vice versa, focus ring is closer to body- focus ring takes too many turns. While this makes it more precise, it slows down focusing especially if shooting video- while it came in a nice acrylic box (as shown) it does not include (cheap) lens cap covers as I got with a 35mm CCTV lens I purchased.

    Fun toy

    5/5 The Cheese - See all my reviews Verified Purchase(What's this?) This review is from: SainSonic 25mm F/1.4 C Mount CCTV Lens for Pentax Q P/Q Mount Interchangeable Lens Camera (Electronics) Using this with an APSC Sony a6000, and it works nicely. The vignetting is severe, you get a full circle of black on APSC sensors. If you have an MFT sensor this would be perfect. The sharpness isn't tack sharp when wide open, and when you stop it down it gets a swirly effect due to the imprecise/irregularly closing aperture blades. All this may sound bad, but it is a cool effect and you can't get this look with the ultra precise computer engineered lenses found on most modern cameras. I would classify this as a toy lens when used on MFT or APSC. This will not work well on full frame because the full circle of black vignette would reduce the visible part of the frame to about 30% of full. Even APSC reduces the image to about 60% of the frame. The best use of this lens is for antique looking images or to get a 1920's movie look., August 29, 2015

    1/5 Michael - See all my reviews Verified Purchase(What's this?) This review is from: SainSonic 25mm F/1.4 C Mount CCTV Lens for Pentax Q P/Q Mount Interchangeable Lens Camera (Electronics) I was so excited to get this lens. As a very low budget Filmmaker, you could only imagine my excitement in finding out about "vintage lenses". I will admit that I was a bit skeptical upon ordering it; I mean, come on, 19 dollars for a lens? Sounds fishy. And truthfully, I'm not creating a big stink about it at all. BUT, the lens came in and as soon as I pulled it out of its box, it came out in pieces. I manged to securely put it back on and slap it onto my Canon 60D. Damn, was I ready to see the magic of this cheap vintage lens.Nope. The focus ring does not work. Then, to top it off, it got so badly stuck in the adapter that I purchased for it. I thought I would break the adapter trying to twist it off.Anyway, I was upset that this product came in in such poor condition. I'm returning it and I already have another on its way. I really, really want this lens to work out. I will report back on how the new one comes in! Help other customers find the most helpful reviews  Was this review helpful to you? , January 8, 2017

    Photography (uxcell)
    List Price: $9.06

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