I ordered this CPL lens filter for my iPhone 15 Plus as I have been wanting one to help reduce glare when taking photos through windows and also cut sun glare in outdoor shots. I was excited to try it out and took comparison photos from my kitchen window and out on my back patio, both with the filter on and with it off.So far, I haven’t seen a big difference between the photos taken with the filter on versus off. In particular, the filter didn’t really reduce the glare in the photos taken from inside my kitchen window, and the colors in the photo of the horizon taken from my back patio don’t seem better than the photo without the filter. However, I may not have rotated the filter enough or in the right way to reduce the glare more than it did in my photos. It may also be because I’m testing it here in December in the cloudy Pacific Northwest where the sunlight is limited and low in the sky. I’m looking forward to trying it again in sunnier weather when conditions are more challenging for glare.As shown in my video, the filter easily screwed onto the clip, and the clip attached securely to my iPhone 15 Plus. The filter comes in both 58mm and 67mm sizes. I ordered the 67mm version after doing a little research and reading that the larger size is better for covering the full lens area, especially on newer phones like the iPhone 15 and 17 that have larger camera modules. The 67mm filter fits my phone fine and might even be slightly oversized, which I don’t mind since it gives me flexibility if I upgrade to a newer phone later.The kit also came with a zippered carrying case and an orange wrist strap, which makes it easy to bring along and keep everything organized. The case feels sturdy and compact, and it’s a nice touch for protecting the filter and clip when not in use.Overall, the filter is well made, easy to attach, and fits securely. As you can see in my attached comparison photos, the difference isn’t dramatic yet, but I’m optimistic that it will perform better in stronger glare conditions. I rated it four stars instead of five because I haven’t seen the filter make much of a difference in my photos so far. I will update the review if I get significantly different results in my future photos.
