This is a manual focus lens, but it's very promising, 12mm wide for FF, f2.8 fast, almost zero distortion and cheap price.
I think I'll sell my Canon for this one.
First I thought of a Samyang, but they had moustache distortion which is hard to correct.
This brand seems to produce limited but speciality lenses, anyone bought a lens from this brand yet ? (Venus Optics)
