Last week I invested in getting a macro lens, the new Tamron 90mm f/2.8 Macro SP.  For those of you with really good memories, you will have realized this is my third Tamron lens in the past 9 months.  Tamron is just simply producing the best lenses available for Nikon right now.  I had the Nikon 105mm VR Micro (they use micro not macro in the name) lens from 2009 until about 2013 and loved it.  It was such a fun lens to shoot with, as making macro shots always had a sense of wonder at showing a hidden world the naked eye cannot see.  It had very creamy bokeh and was very, very sharp.  I also loved it for portraits and just as my walking around lens.
