~ There are shots which stretch the technology and the photographer's skills to the limits…this series of Aethopyga siparaja, Crimson Sunbird, was taken at a considerable distance, with the bird appearing as a remot speck hopping around in shady foliage…that these images are at all usable attests to the resolution capacity of the EOS 1D Mark IV and the EF 400mm f/5.6L super telephoto lens
