im looking for a good (the best ) 10 or 12mm to be used in both photo and video. auto focus is ideal but not necessarily important. looking for excellent image quality, large aperture, excellent bokeh, no or minimal barrel distortion and edge/corner softness, not too big - in that order. ive looked into the oly 12mm/2 (probably my baseline), slr magic 12mm/t1.6 (excellent bokeh, slight softness at max aperture), rokinon 12mm/2 (great value for money, not as good bokeh). among those three, which one would you suggest? also if there are others i should look at/consider please post them here.
