First of all, for handling: The lenses are screwed into a clothespin-like mount, they are then placed over the camera phone with the help of those. This works as far as faultlessly; However, you should make sure to position the lens really well centered over the camera, otherwise drops the already not exorbitantly high imaging performance on underground level quite quickly. Theoretically, the clip also attach, without removing a possible in-use protective cover from the phone, I can recommend this at least the iPhone 6 not: Since most cases have a single cut-out for camera and flash, does not include the patch lens around tight fashion and it may come up at the side scatter light, which reduces the image quality noticeably.
The clamp sits pretty sure on the phone, so you have to have no fear, they could accidentally fall off at least as long as no one touches anything. It should be pointed out that the macro lens is part of the wide-angle lens. For macro shooting you so it must unscrew. That's easy. Sometimes unfortunately too easy. It happened to me several times that I wanted to screw the whole wide-angle lens of the retaining clip, but ultimately only the upper part was in his hand. Not so tragic, but in the handling partly something friemelig.
Among the different lenses following things are to be noted: With all you can have fun, the picture quality decreases but from Macro on wide angle fisheye to my opinion always further.
The macro lens can be relatively amazingly good close-ups from the lowest distance make. At least the central areas of the image are still quite crisp sharp. So if you like once close-ups of insects, flowers or whatever else would ever do, can hereby actually have fun.
The wide-angle lens is also quite to use yet. I feel that after the resolution is acceptable to the edge are of course already distortions to notice. For one or the other. Overall, however, can certainly be quite pleasing shots with this lens make.
When fisheye lens you should just be aware that it certainly has its place for funny recordings; or for pictures where it does not depend on details and accurate imaging. That a fisheye lens reflect strong barrel-shaped distorted, lies in the nature of things. In so one should not complain. With the present lens position but any part located outside the direct center of the photo to be displayed quite heavily blurred. To what extent that is still acceptable for the individual user, just everyone has to judge for yourself. In addition, it should be noted that their design is created an annular black border around the picture.
So what remains the bottom line? I had already quite some fun with these lenses, but higher photographic claims they will not certainly do justice. Meanwhile, every buyer should be aware in advance; However, each of them different expectations given the very reasonable price would be presumptuous plentiful.
