I’ve used a number of filters like this one and I’m happy with this one. It reduces light intensity on photos taken with my iPhone camera app, but it’s very subtle compared to some of the others I have used. Rather than increasing the contrast, it tends to crudely, darken the images. This can be really useful when it is very bright outside, but if you take a photo indoors, the result is usually that the brighter colors are just simply dulled. I actually kind of like this effect as it can make images to seem muted. I was expecting it to reduce glare and reflection, but I didn’t really see that in any real situation’s. It’s basically like putting sunglasses over your phones camera.The lens is rather lightweight . The lens plus the case only weighs 114 g while the lens itself with the clip only weighs 61 g. The lens and adapter are small and light enough that I wouldn’t have any problem taking it out for a family excursion. The resulting images I think are worth the minimal added weight.The set also comes with a lens cleaning cloth in a wrist lanyard. Both of which are welcome additions, but I don’t think I will be using the lanyard much if I’m carrying the case with me.The adapter allows you to screw on other 67 mm filters, but I have not tried that because I mainly use 58 mm. However, it is fairly easy to screw on and off the filter, and once screwed on it feels very secure. The clip that secures the adapter to your phone is very nice. I’ve had others like this that press hard metal onto the phone screen. This adapter has a rubberized component that touches the phone screen, ensuring that you won’t damage your screen while clipping on the adapter.I think the filter is a quality accessory for any phone photography enthusiast. I think the asking price at time of purchase is on the higher end, but I do think after using it for a time it’s worth the price. Five out of five stars.
