When I still had the 23HR it basically was able to shift the same with my IQ150 as it did with the P40+. The biggest issue I had, which was why I eventually traded my lens was with the red center hot spot flare that was extremely easy to invoke. It was definitely more prevalent with the IQ150 CMOS than it ever was with the CCD sensors I shot it with (P40+, IQ160, IQ260).
Newer versions apparently have a new coating which addresses the flare. I haven't tried the newer ones though. Newer versions of Capture One Pro definitely helped with better LCC's - I would say that what seemed like worse fall off / discolouration with the IQ160/260 were a lot better handled with C1 and the IQ150.
