It also focuses as close as 16 centimeters, providing an unusual combination of close focus and wide-angle perspective for 1:4 macro photography.The 24mm focal length, equivalent to 36mm on a 35mm format camera, is an excellent choice for general shooting.

Movie makers will love this lens too, because smooth, low-noise autofocus and aperture operation mean they can take advantage of its outstanding optical characteristics without worrying about mechanical noise infiltrating the soundtrack. • Weight (approx): 225 g • Dimensions (Dia.
