It's a great bargain lens, same as the Samyang which I have in the Pentax mount......... need stopping down to be sharp at the edges....great colours............it's real trump card is it's resistance to flare, straight into the sun and all you get is a couple of small flare pips...
It's also a stereographic projection lens.
