This SLR Large Lens icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
It's a logo for an SLR large lens and has a top-down picture of a camera with a large lens. There is a shutter button of the right side of the camera and a large lens made up of rectangles coming out of the top of the image.
