I can speak about the CZ P100. Being an older generation of Planar, it has lower contrast w/o and less optical correction all around. Unlike most Planars, the bokeh is beautifully smooth. It has freakishly low linear distortion and is, therefore, just perfect for cityscape: I call it an infinity-focus makro. Perhaps because the sharpness is merely moderate when w/o, there is no glaring LCA, although it's not an apo. In keeping with the Contax RTS line, and because of the long throw, the DOF scale is real and usable. I was never willing to mount it on my Canon D30/1Ds bodies because the large "shark fin" would grind off plastic from the mirror box. All that is past history with the A7ii:
I don't shoot portraits @ f/2, but this was a studio test and, no, the lens does not vignette at top-of-frame!
