This is a SLR Filled 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 13,000 icons, all in the same style and quality.
The logo for looks like a simplified image of the top of a camera. It kind of looks like an L that is laying on it's back with the bottom pointing up to the right side. There is also a double circle, a black dot, a striped rectangle, and a curved rectangle on the image.
