This impossibly long, 90 meter shot of a shy and rare Philippine endemic made it to my elite list for the following reasons - rarity of bird, endemism, difficulty of capture and good technicals (framing, sharpness, exposure, background and pose). This pic, taken at 1600 mm with the Sigmonster + 2x TC, is one of those shots where the photographer wishes for perfect execution (shake control, MF accuracy and timing of shutter press) to squeeze out a half-decent image from that distance and focal length. As it turned out, everything went well and the equipment delivered to its potential.
