RED has announced the imminent release of an adaptor that allows users to shoot with Canon lenses with the RED EPIC, in place of the standard PL mount. Manufactured from titanium, and with a lock ring to ensure that long lenses are held securely, the lens adaptor is “smart” in that it can control camera iris, image stabilization, and autofocus electronically, via the various standard control options with EPIC (e.g. touch screen, side handle, REDMOTE). Vincent Laforet has published some footage using the camera with Canon long lenses and a prototype adaptor on his blog.
There is a full list of supported lenses in a thread on the REDUSER forum and the adaptor will start shipping on 9 September at a price of $2,000.
