I have had this lens for several years using it on my d7100. Very pleased indeed bought it to shoot a wedding along with a 70-200 and it's the perfect focal length to capture groups and small details . The macro end is stunningly sharp at f4 .
Tried out D750 at Photo show in Nyc:-) I had Iso at 8000 Omg amazing. I may have to sell my first born!
