The lens has a focus-limiter switch with three choices: 1.4-4m, 1.4m to infinity (the entire range), and 4m to infinity. There's also a programmable function button and stabilizer toggle.
If you need more reach, Olympus' 1.4x teleconverter can increase the effective focal length to 420mm (a 35mm- equivalent angle of view to 840mm) and 0.67x magnification.
