Cell Phone Camera Lens, SEVENKA 12X Telephoto Universal Clip On hd Lens Compatible with iPhone 12/11 Pro Max X XS Max XR/8/7/6/6s, Samsung, Android and Smartphone with Travel Case

I was initially wary of the other reviews, but I found it works just fine. Picture is clear if you align and focus properly, and it’s easy to mount and cheap.It does slowly slide down if you hold it vertically, but it’s very easy to just hold in place.

Purchased this camera lens to use on an upcoming trip. The lens itself was poorly made. It’s plastic, and when I tried to thread the lens to the camera attachment it would not thread unless you pressed really hard trying to get it it start threading into the camera attachment part. The actual view is obstructed also . It has a very narrow field of view. Don’t waste your money.

I bought this to take better pictures at concerts. The zoom works super well as I tested this at home first. However once the lens is attached to the clip, it partially blocks the camera (creates a vignette effect) on my Samsung Galaxy S10e so I did return it.

I am impressed with this telephoto system on my iPhone 8.MechanicalAttaching a telephoto lens to a smartphone in a manner that is easily reversible and does not damage the smartphone is quite a challenge, and this solution is one of the best I have seen. Of course, aligning the optical axis of the telephoto lens to the optical axis of the iPhone camera is difficult, requiring a positioning accuracy of something under a millimeter. This is not the fault of the telephoto lens; it is the inevitable consequence of the design of the smartphone camera. A particular strong point of this design is the way that the lens screws into the mount so that the eyepiece of the lens is flush with the surface of the iPhone. This produces the best possible optical performance. Some of the mechanical systems I have seen unavoidably establish a gap between the telephoto lens and the camera lens of several millimeters, which leaks light and reduces the size of the final image in the smartphone.All smartphones pose a special challenge to the designers of add-on optics: many smartphones place the camera lens close to the corner of the phone. In the iPhone 8, the camera lens is only 9mm from the left edge of the phone and 10mm from the top edge. This limits the size of the area that the clip can grasp. The eyepiece lens is 14mm in diameter, meaning that the outer edge of the lens is just 2mm from the edge of the phone. It’s difficult but not impossible to get the lens lined up properly.Once the lens is correctly mounted, the support structure is solid enough to hold it firmly without any shaking.OpticalThe optics of the telephoto lens live up to the old saw that “You get what you pay for”. A decent-quality telephoto device with these specifications would cost at least $50. This telescope suffers from chromatic aberration (a black line has a red edge on one side and a blue edge on the other); spherical aberration (a straight line along the edge of the field of view looks curved) and plenty of internal reflection. I attach an image demonstrating the chromatic aberration and the internal reflections. I must advise that this is an extreme torture test that exaggerates the weaknesses of an optical system.Overall
This product is excellent for the price. If you want really great telephoto images on your smartphone, be prepared to spend a lot more money. For $14, this is a great buy.

I got this to try and take some good photos from far away at a Taylor Swift concert and overall I am happy with it! The photos I put were the best of all the pictures I took, unfortunately it was kinda hard to keep the lense steady so a lot of the pictures were blurry but I am impressed with the good pictures I got anyway. It did not work to take photos of just Taylor from where I was sitting, she was too far away, but it worked amazing for the screen behind her.A tripod would probably be helpful (they didn't let any in the venue I went to though). I'd say keep in mind that the quality of the photos will depend most on the quality of your phone camera, I tried it on a phone with a worse camera and the photos were pretty much unusable. I wish that the lense itself was able to change the amount of zoom, it was a lot too zoomed in at some points. This lense is pretty good for the price so if you want to try it out I'd say go for it but I think next time I would spend a little more on a more complex lense now that I know how well something like this works.I had no problem getting the lense on the phone or having it stay on. It was easy to remove quickly too when I wanted normal photos, I just didn't use the screw it came with. I got it to work on a iPhone se, OnePlus Nord N20, and iPhone XOh and the telescope worked fine too, perfect for spying on the celery tents lol

The lens is fine, it’s the mount that’s the problem. If you have a protective case for your phone it will not work. You must take the case off. The lining up the lenses, good luck. If you can it will not stay in place. I took a chance paying $12 for it. I would be pissed if I payed one cent more. It will live in my junk drawer

I am very impressed with how simple and intuitive this lens is to use. The universal clip attaches securely to my phone and aligns easily over the main camera lens without slipping around. It is lightweight, compact enough to slip into a pocket, and instantly upgrades your smartphone photography game. Finding a reliable zoom lens that doesn't cause terrible distortion or blurriness around the edges can be tough, but this model delivers great results. The build quality feels solid and durable, not like a cheap plastic toy. It forces you to get creative with your smartphone photos and offers incredible value for the money. The magnification is powerful enough to pull distant objects right up close without losing image quality or turning the photo into a pixelated mess. The HD glass provides a remarkably crisp and clear view. It is perfect for bringing along to concerts, sporting events, or nature walks. Easy to Clip On and Works Flawlessly! Highly recommended!

It's a cheap piece of crap that is hard to put on the phone rapidly. It only works if you have it sticking out of your phone the entire time you are exploring a place and the zoom is not that profound.

Nao funciona, nao se adapta ao iphone 17 pro max , nao recomendo . Devolvi .

Es difícil de ajustar además de que es muy inestable y algunas veces queda más grande de la cámara del teléfono o más chiquito
