Any C-hing knows whether this is a good lens for Birding..or should I consider
Canon 400mm f4 DO lens ?

Many thanks for all CHings valuable recommendations .. I was in Danum Valley, Sabah in January..with my 7D + 100-400mm , I found the zoom not sharp enough once reach 350mm up .. I am looking at the 400 DO for a reason becos I want to go back to Rainforest for birding. However, found the daily sudden rain really shock me if the Gears are too big and heavy
to carry inside the jungle .
