The gap between smartphones and cameras has always been due to one element: the lenses. The growing quality of sensors in mobile devices is undeniable, as are the wonders done by artificial intelligence, which succeeded in making the most of miniaturized photographic sectors. But the weak point of those who have chosen to shoot with their phone is always represented by the lenses. For this reason, lens kits are being created today in order to bring smartphones even closer to cameras. Or at least to compact cameras.

Black Eye's Pro Kit G4 is one of the most convincing products, a three-lenses set designed specifically to combine quality and practicality. Inside a protective case you find four lenses compatible with all smartphones, both iOS and Android. Thanks to a clip, the lenses can be easily mounted onto the smartphone, and you don't need to do anything but choose the right lens. 

The Pro Cinema Wide G4 lens extends the angle of view of your smartphone camera to 120 degrees. It is designed for both photos and videos as it allows you to shoot amazing photos while avoiding the typical corner distortion of wide-angle lenses. Then there is the Pro Portrait Tele G4 lens. It gets you 2.5x closer to your subject, and it feels like shooting with a 50mm lens on a full-frame camera. As the name suggests, this lens is mainly designed for portraits, but allows you to capture distant elements without needing to get extremely close, too.

The last lens, the Pro Fisheye G4, takes its brother - the Pro Cinema Wide G4 - to extremes, thanks to its 175-degree angle of view. These are important numbers, which give photos, but especially videos, that famous fisheye effect that many people associate with GoPro, the action camera that made this so popular in the first place.

It goes without saying that like any additional lens kit this one too, even though it's portable, is not as practical as just picking up the phone and shooting. But if we compare it to real cameras like compact or mirrorless, the Pro Kit G4 has many advantages.
