I'm not saying I don't want to buy the Z 58mm Noct, but for that price, it better have zero, and I mean ZERO red/purple/green/cyan fringing, in or out of focus, even wide open, and needs to be sharp corner to corner at f/0.95.
Otherwise, why not wait for the 50 1.2 S? Speaking of 50mm lenses, I'm glad Voigtlander has announced a new 50mm f/2 APO for Sony users. Nikon users can use it with an adapter. Preferably a "dumb" adapter.
Bernard, did you actually record photos taken with the 58 noct? I didn't know the prototype was an actual functioning lens...
