The Best Portrait Lenses?

My new favourite (after the 24-120/4 ;-)) is the 28/1.8g. Wider than 35, so full - body capable, not as wide as 24 (which is pushing things to the limit). I am finding that 'environmental portraiture' is what I like best. Head and shoulders or headshots have their place, sure, but I like to get a bit of context in if I can. I'm just learning my way round the lens, but when I get it right I prefer it to any other FL.
