Minolta had two f/1.2 lenses in their MD lineup. The 58mm f/1.2 was
one of my favorite "bokeh" lenses.
While the 58mm f/1.2 Rokkor has developed a cult following for its sharpness and bokeh,
the 50mm f/1.2 Rokkor is somewhat more rare on the used market.
Which one is better? Well, let's just say the 58mm f/1.2 "RoK" has more character,
while the 50mm f/1.2 "RoK" is somewhat more "boring" but hey, they're both great in their
own way. Love 'em both! :-)
