Best I could do from a moving canoe with a manual focus 105mm and a 2x TC. Not sure if the 300mm would have done better with the motion of the boat. Saw about 2-3 eagles on this paddling trip.
Pentax Program Plus, Fuji Provia 100F, 210mm. Cropped to about 30% of the original frame to make up for lack of tele range.
