Kipon has released a built-in aperture Micro Four Thirds adapter ring. It is the world's first Micro Four Thirds adapter with aperture control for EOS lenses. Check it out in action with a 50mm Canon lens and the Panasonic AG-AF100 camcorder on Vimeo
Up until now, if you wanted to use a Canon EOS lens on a Micro Four Thirds camera, you had to set – and stick with – a single aperture as current adapter rings lack the electronic communication required to change it. The Kipon EOS-m4/3 adapter super-cedes this problem by featuring a built in aperture ring you adjust manually.
EOS-m4/3 A breakdown:
Use your Canon EOS lenses on your Micro Four Thirds Camera
Built-In 14 blade aperture iris
Aperture dial labeled 1 to 6 instead of actual f-stops
Only EOS to M4/3 adapter on the market that lets you adjust aperture
