This is a Switch Camera icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,900 icons, all in the same style and quality.
The outer edge of the icon is in the shape of a hand-held camera that one would take pictures with. The shape is rectangular with a slight bump at the top, similar to a camera. Inside the rectangle are two arrows that form a circle with the arrows pointing in a clockwise direction.
