So 18/19mm since we're talking crop sensor I mean. If 28mm is one of the most popular street photography focal lengths (Leica Q, Q2, Ricoh GR series, Fuji x70, etc), why haven't more lenses been created for this niche? Like, there doesn't seem to be a single lens out there to rival the Leica Q's fast 28mm. TTartisans, 7artisans, Mitakon, no one? No 18mm f.95, f1, f1.2? The closest thing is the rokinon 21mm f1.4, which comes out to about 31.5mm in full frame terms. I believe f1.4 would be equivalent to about f2 on full frame.
Of course I'm not expecting this from fuji, nor anyone else to come with AF.
Anyone else surprised by this though? Any thoughts? Am I overrating the 28mm focal length?
Edit: also, what about weather sealing? is this too much to ask from a third party lens maker?
