Is basically a circular polarizer that you can attach to a phone and I pretty much love everything by k&f concept. I've been doing photography for a very long time and I really love this brand and the majority of their products and I think that they're A Step Above some of the other ones. As soon as I seen this I grabbed it just because I like to do a lot of photography on my phone and I already knew that this was going to be a very good purchase. And one of my favorite lenses to shoot actually has a 67 mm filter size so I popped it on there and sure enough it works like a charm. Overall this thing is super easy to use and I think it's a very high quality filter the build quality is pretty much Second To None except maybe some of the very very high-end ones but for the value for the money and the price paid I think it's very good. This is super cool comes with a little pouch the clip and the filter and it makes upgrading your phone photography definitely taking it to the next level. Overall highly recommend

I produce videos for my YouTube channel. Many people enjoy videos of driving around in a car, particularly in cities far from their own homes. I live relatively close to New York City and frequently create videos of my travels around the streets of New York City, which many people who don’t live in the city enjoy.I do get complaints from people when I’m driving into the sun, and the sun's glare reflects off the window and the dashboard into the camera. I tested this new lens today and found it to be effective when driving into the sun. It reduces most of the glare from the sun. This will be a very valuable tool for my YouTube business. I always apologize while videoing for any glare they may see.I’m not sure how the technology works. Still, it seems to filter out a lot of the sun’s glare and the streaming that you get from sunlight coming in through your camera through windows and reflecting on other objects. The reflected light is also blocked to a reasonable extent; it's not perfect, but it's much better than this without it. This is a very worthwhile device for anyone serious about taking videos or photographs with an iPhone.

Good !

This little filter really surprised me. I mainly use it with my iPhone 13. The biggest difference I noticed is in the sky. Blues are deeper and clouds stand out more. Reflections on water and glass are reduced significantly. It's great for outdoor photography. The clip itself is easy to use. It fits securely on my phone without blocking the camera. The build quality seems pretty good too. It feels solid enough. It's not perfect. It can be a little fiddly to align correctly. You need to rotate the filter to see the effect.

If you want to improve your phone photography it’s worth getting a filter to bring out some additional optics that the phone’s lens can’t.This is a camera filter with a peg to grip over your phone’s lens(es) and take advantage of better contrast and reduce reflections that daylight bounces off. Its size means that if you have more than one camera on the back of your phone it should cover the others too, but it will also cover the screen too, so you may have to adjust so your controls aren’t blocked.Although to do that you’ll actually have to override your phone’s default auto adjusted images and do things a little more manually, or even shoot raw if your phone is compatible. If you just clip this on and expect to see any difference your phone will just readjust the colour balance to what it thinks looks best - so tap and hold to lock in your exposures!This filter comes with a thread, meaning you can twist it your my phone camera and attach it to any camera with the same diameter or use step-up/down rings and take advantage of having a filter across all your electronics!There’s a soft ribbed edge to twist the polariser comfortably and work out the distance it’s travelled by feel, although it would be handy to have marker dots on the rim to or mechanical stop to know the intensity you set the polariser to.While not an essential, it is a nice to have for those upping their iPhoneography or who also have a camera to get even more use out of it.

This is a nifty gadget for phone photography. The clip is snug and secure. Brilliant gift for any photography enthusiasts.

Using it for my iphone 16 pro max and it’s perfect. Captures better videos and photos especially when the sun is so harsh. Very quick and easy to attach and remove. Comes with a hard case too. Highly recommend. Good value.

Great for sharpening images and minimising sun glare.

I have several K&F products and they have all proved to be well built and effective, this 67mm K&F clip on polarizer is definitely up to the same high standard as their other products in my kit and as usual, really well priced!This clip on filter is mostly used on an older non AI assisted phone camera so the results are very much true to what you see through the filter at the time of shooting. I have tried using this filter on an AI assisted camera but find myself going back to non AI camera as I just know where I am with that.The filter is supplied in its own protective case which I have colour coded with acrylic paint, this is due to having two other identical filter cases in my kit and gives me a ready reference to which filter I have in my hand. The case is soft but robust and does a great job of protecting the filter.You'll soon find practice makes perfect when using the K&F filter, like most things in life there is a learning curve to complete before you get the best results from it, this said it's a short curve and it's not like you have to spend hours in the darkroom waiting to see the results
