Houston Zoo 2017 with the Bigger Cahoona - Flamingo Waterfall

They say that it's difficult to do hand-held shots with the 850, but for the most part I beg to differ...a steady hand with a VR lens will do just fine.

For shots like this, though, with a shutter speed of 1/6 second, you do have to do something.  Fortunately there was a wooden fence enclosing the flamingo area and I was able to use my radiulna tripod, which goes with me everywhere.
