Adapted the Samyang 85mm f/1.2 XP EF via MC-11, I have to say it's a joy to use and I actually quite like the unique waxy shimmering crystalline bokeh texture in some situations.
CA is somewhere between the 35 1.4 ZA and the 35 1.2 ART. I actually like the balance.
It's huge but cheap...I got mine for $580, but there are a couple left (same lens as Rokinon 85mm 1.2 SP) on BH for 640 or so. Pretty good value imo if you like MF.
