An image capturing device comprises a viewfinder, a lens and an adjusting member. Light enters the viewfinder along a first central axis thereof. Light enters the lens along a second central axis thereof. The adjusting member connects the lens and the viewfinder, rotating around the second central axis, thereby defining a focal length of the lens. The first and second axes cross each other at an intersection when the adjusting member impels the viewfinder to rotate, wherein the focal length is substantially equal to the distance from the lens to the intersection.
