Idea of Focal Length Icon
There is a single cone shape lying on it's side with the tip to the left and it's bottom face visible on the right side, beaming off the top and bottom of the bottom face is two diagonal lines, and halfway through each diagonal line is a curved line connecting them.
This is the Focal Length icon for Windows 10
. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
