For portraits: the 110mm is gorgeous at F2.0 and 2.8, best portrait lens I've ever had and I rate it 10/10. Everyone expects a lot from the new 80mm too. The 250mm is also really nice for portraits, 8,5/10.
The 50mm is said to be slightly better than the 45mm which I have and rate 7,5/10. The 30mm I haven't used very much yet, 7-8/10 for the moment. The 63mm is OK but nothing really special, a 7/10. The 120mm is really sharp, could be good for landscape but a no-go for portraits.
I had the 32-64mm, it's really sharp but has -imho- no character, 5/10. I really dislike zooms so I'm totally biased .
