When attached to a lens having a focal length of F, a 1.4Ã TC results in an effective focal length of 1.4ÃF, whereas a 2Ã TC results in an effective focal length of 2ÃF. Thus, a 400mm lens with a 1.4Ã teleconverter attached provides the same magnification as a 560mm lens, since 1.4 Ã 400 = 560. Similarly, a 400mm lens with a 2Ã converter produces the same magnification as a true 800mm lens. For birders, teleconverters can be a godsend.
