I have spent 3 days at Tang Jia He Nature Reserve in Sichuan province, China. I have taken 2 long focal lens with me, a Nikkor 400mm f/4.5 lens and a Nikkor 800mm f/6.3 lens. I always handheld one of them and put another in my backpack. I switch them from time to time according to the distance btw animals and myself. But I must say in 90% chance I need the 800mm focal lens because the wild animals are quite far away. I’d like to share some of the images I have taken in this trip. All of them are with the 800mm lens.
