Canon EOS-1D X / Canon EF 500mm f/4L IS II USM pictures from canoe

Last few weeks I have spent photographing from a canoe with Canons equipment

Canon EOS-1D X / Canon EF 500mm f/4L IS II USM,  and I´m very content with the result.  When you move on the water absolute silent it is possible to get really close to birds and other animals; so far I have got pictures of Beaver, Moose, Black throated diver and Whooper swan from the canoe.

 In June it is possible to shoot all night through in the marvelous light. Canon's new EF 500mm f/4L IS II USM   is no problem  to hand hold from the canoe. I have also tried longer shutter speed  and it looks like the image Stabilizer works well if the canoe stand as still as possible in the water.
