At The River With The Nikon F

 Cool Fall weather has brought the Sandhill Cranes back to the Rio Grande Valley.  I've taken a couple long walks along the river to photograph them with my Nikon F and the Vivitar 70-210 Macro Focusing Zoom.

The Vivitar lens seems a versatile performer, though I found it challenging to get it well focused at maximum extension.  I think I likely just need more practice using it.
