Image quality is good enough for the cheap cameras that these lenses fit. A good price for a useful range of lenses. No markings on the lenses, and the stickers don't always stay on the caps. There is a big gap in the range between 6mm and 3.6mm, and I really needed something in between. No IR-blocking coating, so there will be some false color if there is no filter on the sensor, but this is okay for security cameras. If you need the flexibility of having a whole set of lenses, get this. I bought a few sets myself. Read more

This is a realy good and useful set of lens to update a existing camera or to find out what lens are best for a given situation. The construction is realy good and the price is also great. The lenses are from a good maerial and clear and the caps are a good addition. Not a con but a idea is that the data on the cap could also be engraved or printed on the lenses itself. I didnt found other real cons. A box for storage would be a good addition but would probably made it more expensive. Great lens, good price and a nice addition for a wide range of web and Surveillance cameras. Read more

Lens have metal body and thread easily into the several lens holders I have tried. These lenses do not have an IR filter and can be used with night vision cameras. Not a negative for me, but some might like to have the focal length labeled on the rim of the lens. Again, not a negative, but since they pass IR, objects illuminated with daylight will not show true colors, as humans perceive them. These lenses will not work in cameras with a very short lens holder that has only about 4 or 5 threads. The lenses have to be spaced out from the sensor a few mm to focus. I found a longer lens holder and replaced the one on the camera. The mounting holes in my camera PC board had to be filed to fit the closer mounting holes on this lens holder. Otherwise, it would have to be glued to the board. A very good set for the experimenter and general user. Read more

- a very wide range of sizes for a low price; - a very good amount of glass in each piece so more light reaches the sensor - for some reason they the manufacturer has decided to spare some plastics and made the lens of longer focal distances (12mm and 16mm and who knows why 6mm too) a bit shorter... - a very wide range of sizes for a low price; - a very good amount of glass in each piece so more light reaches the sensor - for some reason they the manufacturer has decided to spare some plastics and made the lens of longer focal distances (12mm and 16mm and who knows why 6mm too) a bit shorter in the threaded part and it falls of my cam's mount just before it can clear the focus I bought this to replace the lens of a webcam for a specific project. Unfortunately the focal number that'd have suited me best was 6mm and I couldn't use it for the above mentioned reason so I put the 3.6mm on (same as my old lens) as at least this one gets me a brighter image (and more fps) Good buy if you have enough length on your lens mount's tube and you need aim for low light performance (no IR filter here so color images are not what one'd usually expect to see) Read more

Great set of lenses, sturdy, comes with a cover for every lens. No cons. Note that these lenses come without any filter. This means they can see infrared. Using them with a modified PS3 camera (as I do) this means the colors in the image will be much distorted, unless you use a filter that lets through only visible light (these are very hard to find). It is also possible to see only IR light, using an IR pass filter, for example 850 nm filter. This works great with these lenses. Great product at a great price! Highly recommended. Read more

IR sensitive and fit on almost any inexpensive module/camera. Together with a SONY CCD HAD2 700 line module these are great for overnight surveilance with a minimal of noise.

Together with a SONY CCD HAD2 700 line module these are great for overnight surveilance with a minimal of noise. For people that do not know: 16mm means objects are becomming closer to you, 2,8mm is a wide angle lens. None Together with a good camera module (go for ccd because they have less noise in dark situations ) and a 96 IR led beam you can select the right lens for the application without compromises. Both the IR beam and the camera with lens are situated inside behind my window. The HDD recorder records whoever comes close to my car. Inexpensive and good! Read more

Strong plastic plastic screw Cover for every lens The long screw allows you manage the focus Works great on meny webcams and security cams I found no cons on these item The variety of available lenses is really attractive. It has been extremely useful. I bought it for use in a Play Station 3 eye camera, along with an adapter as this camera does not have native support for this type of lens. It's a nice product. Recommend be sure what type of thread team, if not the same threading light may enter to the camera sensor and this diminishes the quality. Read more

The only real drawback to me is that there are no markings on them (only on the caps) so if you interchange them frequently you might get them messed up If you have a camera that uses that mount, you should get those.

Great lens if you have a webcam that fits these lenses. I bought this for the fish eye, and the picture quality is great, mount is clean and neat, fits well.

I bought this for the fish eye, and the picture quality is great, mount is clean and neat, fits well. Can't find a normal webcam with telephoto or fisheye these do this for you. No cons. - can be tiresome changing lenses though. maybe a webcam with a rotating set of lenses could be interesting. Would make a great accessory for cheap digital cameras, especially since cheap and nasty digital zooms usually ruin a great picture, but these lenses are just great quality. Great web cam accessory. I would have bought the single lens if it was better value for money. Read more
