I recently picked up a Sigma Mini-wide 28mm 2.8 thinking it was a P/K mount, but when it arrived, it turns out to have a Fujica X mount (FX?). Is this rare? Can't find any info on it. Anyway, anyone know if there's a Fujica X - MFT adapter anywhere? Preferably not too expensive cause I'm not sure it's worth it for this one lens. Thx for any info.
