Nikon is rumored to officially announce their new Nikon NIKKOR Z 24-70mm f/2.8 S full-frame mirrorless lens soon. My guess is that we will have the announcement before the CP+ show that starts on February 28th. Here are the rumored details (for comparison, in the brackets you can find the specs of the current Nikon AF-S 24-70mm f/2.8E ED VR F-mount lens):
The Nikon NIKKOR Z 24-70mm f/2.8 S will be the only lens that will be announced. The Nikkor Z Noct 58mm f/0.95 lens will come later in 2019.
