[Leica] R lens recommendation

[ray tai <razerx@netvigator.com>]

I am looking to get into the R system with a short telephoto lens for
outdoor available light, PJ work.  I am leaning toward the 85/1.4 because
of the speed.  Can anyone comment on the 85mm as well as the 90/2, 90/2.8?
I would also like to add that I got into photography with Nikons and my
current body of choice is the F4s.  There has been a lot of posts on the
LUG regarding how excellent certain Nikon bodies are and I wholeheartedly
concur.  However my disatisfaction comes from the inability of Nikkor
lenses to deliver at wide open aperture.  One of my favorite lenses is the
85/1.8 AF but it is really an f/2.8 lens because at wide open it is pretty
disappointing.   And I can say the same about another half dozen other
Nikkors I use.  How do R lenses perform wide open?  I will keep my Nikons
for days when I can shoot everything at f/5.6, and plan to use R's for
those critical wide open shots.  Thanks and happy holidays.
