I own or have owned the 40mm DX, 105mm FX, 70-180D FX all F-mount, 50mm Z and 105mm Z. All are good for purpose. However, the Z 105, in my opinion, provides the best overall image quality and is my go to macro lens for most purposes.. So much so that I gifted the 105 F-mount to my granddaughter, and traded in the 40mm DX. I have kept the 70-180 because I love the "character" and zoom capabilities on my D850. The 50mm Z is for the ES-2 slide/negative copying. These are my preferences. Others will have theirs.
