Venus Optics has announced that its Laowa 4mm f/2.8 Fisheye, Laowa 9mm f/2.8 Zero-D, and Laowa 24mm f/14 2 x Macro Probe lenses will be available in both Canon RF and Nikon Z mounts. All 3 lenses are manual focus.
megadap has announced an adaptor for Nikon Z mount cameras that offers autofocus and auto aperture with Sony and third party E mount lenses.
Tokina has formally announced the test results of their F mount lenses with the Nikon FTZ adaptor and Z7, Z7 and Z50 cameras. The most important information for underwater image makers is that autofocus will not work with both versions of the 10-17mm f/3.5-4.5 fisheye (AT-X 107) and their 100mm macro (AT-X M100 PRO D Macro). Manual focus will work, of course.
