Canon EF 180mm f/3.5L Macro USM telephoto macro lens provides 1:1 magnification and, thanks to its long focal length, allows photographing insects and small animals from a distance. The minimum focus distance range can be quickly limited from 0.48 m to 1.5 m via a switch to speed up autofocus. Three low-dispersion elements suppress chromatic aberrations, and an internal floating element design maintains sharpness at any distance. The lens does not extend during focusing, preventing accidental contact with the subject. Autofocus speed is relatively slow despite USM, so it is best suited for slower-paced work. The very smooth background blur makes it excellent for jewelry photography where optical quality and background rendering are critical. Included: Canon EF 180mm f/3.5L Macro USM lens, front and rear caps, protective filter, hood, tripod collar, pouch.
