UPDATE January 5th,2023: Nikon officially announced the development of the Nikkor Z 85mm f/1.2 S and Nikkor 26mm f/2.8 Pancake Lenses! No pricing or availability information has been provided for either lens at this time, but they're being displayed at Nikon’s booth at Consumer Electronics Show (CES) 2023 in Las Vegas from January 5–8.
Photos of Nikkor Z 85mm f/1.2 S and Nikkor 26mm f/2.8 Pancake Lenses are leaked ( via Nikon Rumors ) which is a sign of the upcoming announcement. So far, Canon has been the only manufacturer with 85mm F1.2 lenses (both for its RF Mount and EF mount ) and now Nikon is joining the camp.

From the photo, I get the impression that the Z 85mm f1.2 will be significantly longer than its Canon counterpart. This seems to be the trend for Nikkor designs, see below how its Nikon Nikkor Z 50mm F1.2 S lens is much larger than the Sony FE 50mm F1.2 GM and the Canon RF 50mm F1.2L USM lenses:

On the other hand, the 26mm F2.8 is impressively compact and would be great match for smaller cameras such as the Nikon Z fc and the Nikon Z30 .
