so- on the macro topic-
found this on my shirt one afternoon and let it hang out on a house plant while I grabbed some stuff....
d750
105mm f2.8 macro
speed light with radio trigger, stand and a small light modifier (I dislike the look of on camera flash)
I rack the focus all the way in to get a 1:1 image on the sensor and just move in until the target was in focus, simple. subject was moving slow or being still, I had lots of extra light and could shoot at f22 for maximum depth of field.
