I love my Sigma 50mm on my D4. I use the 24-70/2.8 on my D810 most of the time. But, my D500 is becoming the camera I have with me the most often. By default, I use a 16-80 on the D500. I am beginning to think I should put my sharpest lens on the D500 and carry it all of the time. Then the D4 and D810 could be "special shoot" tools. What lens would you put on a D500 if "image quality" was your primary criteria?
Robert M. Poston: D4, D810, V3, 14-24 F2.8, 24-70 f2.8, 70-200 f2.8, 80-400, 105 macro.
