Today I brought my dog Mimmi, a coffee thermos and two extreme cameras to the archipelago outside Söderköping. One camera was an old Hasselblad 503 CW with crank and waste level finder, but with a new CMOS digital back CFV50c instead of film back. The other camera was a Canon EOS 1D X Mark II (to be released this summer) with a Canon EF 600mm f / 4 L IS II + 2x III, a total focal length of 1200 mm at maximal aperture f/8. With previous cameras the focal length of 1200 mm didn’t work so good; the maximum aperture of f/8 only admitted one active AF point. But with this new camera, it was extremely easy to focus on a flying white tailed eagle – this thanks to that all AF points were active, despite the fact that the lens had maximal aperture f/8. Once I got the eagle in sight, the eagle remained locked in focus.
