Kosmo- Yup, both the 150/2.8 & 200 APO.
The 150/2.8 is VERY good. It's ULD (like the 120/4) and thus while not APO per se, shows excellent CA control. Resolution is not quite in 200/APO or 120/4 territory, but very close. My copy was old stock NIB and has buttery smooth focus. Has a pull-out hood. Size and weight-wise I often get it and the 120/4 by mistake when grabbing them out of the bag - almost identical.
It has typical M645 high-res but lower macro contrast and nice tonality. The APO lenses, in comparison, tends to be a smidgen more punchy in terms of contrast and saturation. The 150 A pulls WELL above it's price point.
