Nikon D500 Anticipation

Nikon D500 DSLR

  In a blatant violation of my advice to photographers at the start of the year (Five Tips for 2016), I pre-ordered the Nikon D500 and the 16-80mm lens.  According to B&H, my D500 bundle is working its way to me and should arrive early next week.  The timing of this should work out well, as my poor Sigma 17-70 air to air lens is getting pretty beat up and needs to go in for a reconditioning.  

  What am I most excited about?
