Yes, the CA. In some situations it was uncorrectable in Lightroom. Especially in bokeh areas. Also sharpness was not up to Tokina 90mm/2.5 macro. I did try those only wide open though. Samyang would have definitely got better stopped down in that small sensor, maybe I try it again but I don't see much advantage then as Tokina is quite good already wide open. I also managed to fix my K135 aperture mechanism so maybe I try that again also. Somehow the colors were off quite a bit also (heavy violet tint), never experienced this with K-5.
