The 180mm SB f/4.5 is a compact mid range telephoto lens. It yields a good camera to subject distance, slight flattening of portrait subjects and exceptional sharpness. This short barrel lens allows for continuous focusing from infinity to close-up when attached to the Tilt/Shift Adapter. The 180mm SB f/4.5 is optically identical to the RZ 180mm f/4.5 W-N. It covers a wide image area and allows full use of the Tilt/Shift Adapter's capabilities.

The 180mm SB f/4.5 may be used on the RZ camera without the Tilt/Shift Adapter. To use like the standard 180mm lens the 27.2mm Spacer must be attached.

Applications include portraiture, fashion, landscape and sports. Equivalent to 87mm in 35mm format.
