I was lucky to visit , monitor, study and capture another rare Borneo Endemic , Dulit Frogmouth . A real great tour which need to transit flights, 4 wheel, walking over the bamboo bridge ..
A bird I dream to get it picture for so long .. and finally I got few good open shots while casual shooting while assist Ahli Chung (http://www.endemicguides.com/) for a bird watching group… with his good experience we actually managed to see this bird open but I was away from the team for short moment and I missed the first chance .. and I was lucky saw it again few hours later and managed to have few minutes with it …
I am glad that I have chance to test on this len CANON EF 400mm F4 DO IS 2 … I am here just share some actual test result but not compare to other len … except some simple physical compare to my usual tele len CANON EF 500mm F4 IS2 …

CONCLUSION from basic test in low light condition :
1. AF speed is FAST and as good as my 500mm F4 IS2
2. from the picture and more test result , it is sharp and without any weird bokeh appear
3. the size and weight real small and light (about 700gram different with 500mm F4 IS2)
4. easily handheld 😀
