This lens has been factory refurbished by Nikon back to its original condition.
#3 How is this lens for astrophotography? Coma-free at its widest aperture?
The Nikon 24mm f/1.4G ED does not have significant coma correction at f/1.4, but its performance is decent at f/2.8. For a lens that performs better at wide open, very popular choices include the Nikon 20mm f/1.8G ED and the Rokinon/Samyang 14mm f/2.8 ED UMC
#4 is this lens compatible with my Z7 ( I have the adapter)?
Yes the Nikon AF-S NIKKOR 24mm f/1.4G ED Lens is compatible with the Z7 if you are using the Nikon FTZ adapter.
#5 Can this be used with the GH5 and a Metabones Nikon G Lens to Micro Four Thirds Lens Mount Adapter?
Yes but considering the price, you would be better off using this Panasonic 25mm f1.4 lens and no adapter instead: https://bhpho.to/3Cg7VSD. The Metabones adapter would make the Nikon lens manual focus only while the Panasonic 25mm would have autofocus.
