Silica-gel Protective Cover Case and a lens cap
Protecting your camera is important. No matter if it cost 6000$ or 60$, it would be stupid not to take care of it, especially if it can be safe for just a dollar or two. There is an insane amount of silicon gel made, both cover case and a lens cap. These type of gear can be even made via a 3D printer if you happen to have one.
Protective cover case protects Xiaomi YI body. It can not only cushion the fall, if you drop a camera, but also make it scratch resistant. It is similar to those rubberized cases people use for their mobile phones. Additionally, if you are not a huge fan of YI color, this can make it look stylish.
While silica-gel case is not something I use on every day basis while recording, lens cap is a must. And I seriously mean it. If you crash a lens, you would have to replace it. That can cause a lot of trouble and if you do not know how to do it properly, you would have to buy a new camera.
Nobody wants that, right? Especially if it costs less then a dollar. Lens cap protects F2.8 155° wide angle lens, or “eye” of your Xiaomi YI camera.
Lens protector comes in different colors as well. They are also available in different materials. I personally prefer ones made out of silica.
