Tell that to Fujifilm's X-Mount 33mm (APS-C so 50mm equiv.) haha -- but man its fantastic glass even if it is $1400 AUD
Though they have their 35mm WR lens thats a third the price, which is super cheap for the glass quality in my opinion. And you can always slap some older 35mm glass on it with adapters, if you don't mind giving up autofocus.
There is also a 33mm/f1.4 from Viltrox that has autofocus. I haven't used it (my Fuji 35/1.4 has to do) but I own their 56mm/f1.4 and I'm very happy with that particular lens.
It's a classic, super cheap and usually very fast prime that's a recommended starter prime on every photography website I've ever visited.
