Telephoto lens users requiring dramatically increased telephoto magnifications will appreciate the enhanced reach the EC-20 provides. By attaching the EC-20 to a macro or fisheye lens, photographers will be able create new and dramatic compositions from super high-magnification and super wide-angle macro photography.

Without doubt, the availability of the EC-20 provides a whole new world of equipment flexibility and convenience for the professional photographer.

For the sports photographer or photojournalist, the superfast compact Zuiko Digital 150mm f2 (300mm film equivalent focal length) used with the EC-20 provides a combined focal length of 300mm at F4 - meaning that the photographer would have a film equivalent 600mm F4 telephoto lens at his disposal that's no larger in size than a conventional 35mm film format 300mm F4 lens! Nature and surf action photographers using the razor sharp Super Pro 300mm F2.8 lens (600mm film equivalent) will instantly have a 600mm f5.6 lens (1200mm film equivalent!) just by attaching the EC-20.

The ability to double the focal length of the master lens using a high quality compact converter is also very convenient for extended travelling situations where minimising total equipment weight is important.

The splash-proof and dust-proof design and robust construction makes it suitable for professional use.

*When the teleconverter is used, the effective F-number of the lens is reduced by 2 steps.
