**In both June 1996 BAS report (Leica R & M lens), the Leica Elmarit-R
90/2,8 received 92/100 for the quality of the optical part of the lens an=
d
the Leica Elmarit-M 90/2,8 received 94/100.
As far that I know they have exactly the same optical design.
All I want to say is that you have the same different results in BAS test=

than in Chasseur d'Image test, for those two lenses.
But I find those test usefull to.

**N.B. According to BAS test , the new Vario-Elmar-R 4,0/80-200mm
(fotoMagasin 10/96) and the Vario-Elmarit-R 2,8/70-180mm (BAS test 06/96)=

have exactly the same optical quality (98/100) and the same construction
quality (98/100). That great for a 2,8 lens.
