Olympus EC-20 doubles focal length for Four Thirds shooters

The EC-20 is a 2x teleconverter built specifically for the Four Thirds mount system. Mount it between a compatible Four Thirds lens and your body, and you double the effective focal length, a 300mm reach becomes 600mm without swapping glass. One important distinction: this is a Four Thirds accessory, not a Micro Four Thirds one. The two systems share a superficial family resemblance but use different mounts, and the EC-20 will not work on Micro Four Thirds bodies or lenses.

For Four Thirds system photographers who want more reach without the cost of a longer prime, the EC-20 is the direct route. Doubling focal length on a system that already benefits from the crop factor built into Four Thirds sensors means serious telephoto extension from glass you already own.

Who It's For

Wildlife and sports photographers shooting with Four Thirds bodies who need more reach from an existing telephoto lens will find the EC-20 a straightforward solution, the 2x magnification doubles effective focal length without adding a second lens to the kit. Bird photographers working at distance get a meaningful range extension. Travel photographers with a Four Thirds kit who want telephoto flexibility without carrying additional long glass also have good reason to keep the EC-20 in the bag.

Key Features

  • 2x magnification for Four Thirds mount system
  • Doubles effective focal length of compatible lenses
  • Four Thirds mount only, not Micro Four Thirds
  • Extends reach without purchasing additional telephoto glass

FAQ

Will the EC-20 work on my Micro Four Thirds camera?
No. The EC-20 is built for Four Thirds mount only and is not compatible with Micro Four Thirds bodies or lenses, despite the systems' visual similarity.
How much does the EC-20 extend my focal length?
It doubles your effective focal length. A 300mm lens becomes 600mm, a 150mm becomes 300mm, and so on.
What Four Thirds lenses work with the EC-20?
Any Four Thirds mount lens that's compatible with teleconverters will work. Mount the EC-20 between your lens and your Four Thirds body.
Why would I use a teleconverter instead of buying a longer lens?
Cost and portability. You extend reach from glass you already own without the expense or weight of an additional long prime.
Is the EC-20 specific to Olympus Four Thirds bodies?
The EC-20 is a Four Thirds mount accessory, so it works with any Four Thirds body that supports teleconverters, not just Olympus cameras.
Can I stack multiple EC-20s for even more magnification?
The verified specifications do not address stacking or multiple-converter use.
