>>3693415It's already stupidly thin at f/1.2, effectively unusuable. I usually shoot this lens at around f/1.8 to f/2.
But I'm not a photographer who thinks the most important part of a photo is the out-of-focus background :^).
>>3693416Fuji has opened up their format so third parties are jumping on board pretty hard. Already there are: Tokina, Samyang/Rokinon, Zeiss, Meyer Optik Görlitz (or what remains of it), and then a buch of the usual Chinese manufacturers like Lensbaby, 7Artisans/Zonlai, Andoer, Brightin, Hengyijia, Jaray, Kamlan, Kipon, McoPlus, Meike, Mitakon, Neewer, Opteka, Pergear, Sirui, SLR Magic, Venus Laowa and Viltrox.
Sigma is in development.
