Bump for a fantastic lens. I just got one in September and absolutely love it. It's almost always paired to my D750. Yesterday I took off the 24-120mm only because I wanted a slightly wider focal length for the Empty Road Challenge
but put it back on as soon as I was done. I also have an older Sigma 24-70mm f/2.8 that is an excellent, very sharp copy. I wasn't sure I'd like the Nikon 24-120mm f/4 quite as much, but honestly I do. The fact that the Nikon 24-120mm has VR is great (my Sigma doesn't have any vibration reduction). I can use the Nikon during Worship with slower shutter speeds and not have to deal with missed shots like I was getting with the Sigma.
Good luck in your search.
