Mike Tapa has been in the adapter business a long time. He specialises in making adapters to fit most popular stills lenses onto large sensor video cameras. At IBC he was showing his updated Effect EF lens adapter for Sony F3, F5 and F55, NEX and M4/3. Comprised of an electronic adapter and control box, the solution allows full aperture control and image stabilisation with Canon EF lenses when mounted to Sony F, NEX or M4/3 cameras. This is smaller and lighter than the previous version due to the removal of the internal battery pack in favour of an external power connector. Check out the video to see more.
