Do not attach two or more Extenders on the same camera. Doing so will degrade the optical performance and the camera will not be able to obtain proper exposure readings. To enhance water and dust resistance, the Extender EF1.4X III and EF2X III have a rubber ring around the mount. If you used a 1.4x extender then the 100-400 f/4-5.6 becomes a 140-560mm f/5.6-8 lens and that WILL work becuase the wide-open apertures are f/8 or lower for every focal length available. The 2x extender must not be used with any with a focal ratio higher than f/4. Canon EF 100-400mm f/4.5-5.6L IS II USM Lens $2100. Canon EF 300mm f/4L IS USM Lens $1350.
