The *first* thing that this Pentax/Nkion photographer of over 15 years
did upon aquisition of his M6, 35/1.4 ASPH, and 50/2 was to perform
blind A-B comparisons of these lenses with the AIS equivalents. 

At the widest apertures the Leica stuff won for resolution, contrast,
and flare supression. The 35 Leica was better at 1.4 than the Nikon
was at 2.8. In the field (now, based on ~50 rolls of film) I get maybe 
twice the number of sharp exposures at 1/15 and 1/8 as I do with my 
Nikons. At some point perhaps I'll post some 60x enlargements of 
regions of the slides, set up so that the viewer can do his/her own
A/B tests. Of course, at 5.6 and smaller, there was not much difference 
between the lenses; but I think we all know that already.
