The Nikkor Z 40mm f/2 is an ultra-compact prime, ideal for a travel/street lens for those on the Nikon Z mount system. Not a top of the range S-Line piece of glass, but it's a fraction of the cost and sits nicely between the 35mm and 50mm if you don't want to fork out more for one of those.
According to Camel Camel Camel, $248 is the best price on Amazon for this lens so far. Sold by Amazon AU as well, so it will be covered by local Nikon warranty, however, note there is a bit of a wait for delivery as they must be waiting for more stock.
Harvey Norman also have the lens for the same price if you can find stock (none in WA), or want to pay the $7.95 delivery fee.
Wish Nikon make a silver DX 20-23mm version of this then will be perfect!! It will make Z Fc a nice and classy street shioting option.
