The Nikon 105 is a great lens with outstanding Bokeh. It is also great for portraits, and surprisingly versatile.
I also have a D750 that I love, and take it with me whenever I want. It’s heavy, but a good strap makes a huge difference. Put your equipment in a non-descript black backpack (remember a shiny camera bag is a thief magnet!), leave it on the backseat floor...then quit worrying.
I use the nikkor 105mm f:2.8 macro lens for all macro shots. It works great on DX or FX bodies, this one was with my old D5500. Itâs a fun lens to get out and discover the whole miniature world most people never see.
