I use the 35,50,80,100,150,210,300 & the 50-110. Of all of these the 100 would be my favorite for full length if I have enough room to move. I found the 100 is a tad better than the zoom. The zoom is horribly heavy but it is so versatile it has become my most used lens (also hand-held).
I use the 35 quite often as well but found it needs to be stopped down to really deliver.
The 150 is good but less than the 100 or the zoom. It does have the fastest AF of all HC lenses.
The 80 I find good but frankly a bit disappointing.
The 50 I only have for a couple of weeks, sofar it is really nice. Has a fast AF.
The 210 is an excellent lens and makes a nice combo with extention rings.
The 300 is a wonderful lens but I wished I would have more use for it.
Again the zoom is my most used. Especially together with extention rings.
For portraiture I would have the 100 at the top of my list. If working in smaller places the 50 would come in second. I would skip the 80.
