HKSDP (Society of Digital Photographers) organized a one-day tour (from 10:00 to 17:30) to the Mai Po Marsh Nature Reserve attended by 20 members plus four staff of PopArt (HKSDP) and Olympus Camera(sponsor). Its my first attempt in bird photography. Most photos were taken by 70-200/f.28 + 1.7 teleconverter. I ain't so sure whether I'd spend HK$100,000 for the AFS 600/f4.0, heavy duty tripod + ball head etc etc. And like fishing you've to be very patient.
