I spent two mornings and one evening in nature guide Ole Martin Dahle's boat in the middle of May and were able to get some great action shots of white-tailed eagle catching thrown out fish in the water. A 300 mm lens (thank's Ole for lending it) together with my 70-200 mm zoom worked really well for the task and complemented each other. Sometimes the eagles were too close when I used the 300 mm lens on my Canon 7D making an equivalent focal length of 480 mm.
