[Leica] Wanted: suggestions on 21mm

[Ktuckphoto@aol.com]

Dear Luggers,
        Between bikes and scotch could some of the more adept out there give 
me some recommendations?  I've recently converted to the mystic order of 
Leica from the vulgar Nikon following and I'm trying to figure out whether to 
get the 19mm lense for the R series or pick up the previous generation of 
21mm Elmarit for the M series.
Currently have an M6 and M4P with 35 summicron and 50 (latest) summicrom.  
Also have four various R bodies (sl2's and R5's) with lenses from 24 to 180.  
Which system will give me the greatest benefit with the wide angles.  I shoot 
corporate imaging: trade shows, conferences and PR as well as some 
advertising.  Polaroiding with one of the R5's and an NPC back.

One additional question:  I shoot a lot of portrait work and can't decide 
between the 90 Summicron and the 90 Elmarit (both lastest) for that kind of 
work.  The elmarit seems sharper close up and has a very defined look.  Which 
to keep and which to sell.

I shoot for a living and I must say that my clients could tell a difference 
in the imaging of Leica glass from the first moment I switched.

Thanks, Kirk
