I took the Tamzooka off the D7100 to give my arm a rest.  Wish I had it on for these shots. 
		
		
	 
It seems as that (having the wrong lens) happens often to me, too.  I believe your real issue is the great number of opportunities you have.  You could use a 14 - 800 mm f1.8 zoom that weighs 2.6 pounds and is the size of the 105 mmf2.8 Micro Nikkor!!

  Then again, couldn't we all use such a lens.  It would, of course, cost only $495 for the Fluorite version...
