I have the Makro-Planar 120 which I use as my portrait length lens. While it is a bit short, it works fine for me as my studio is very small and I don't have 15 feet to back up from my subject. One complaint that some people have is that the 120 is TOO sharp a lens for portrait work. I have not found this to be the case, but then again, I tend to go for "realistic" portraits, harsh edges and wrinkles intact.
