Gene,

Whaaat?  Do you imply that the M8 has some shortcomings??  NFW! ;-)

BTW, I have recently used a friends full frame Nikon digital SLR with my 
Nikkor 20mm
f4 lens. Very close to the coverage of my 21mm Elmarit on my M4 or 6.  
No filters or
coding needed on the Nikon setup. Beautiful results from a commercial 
print service as
I have no digital photo abilities.

When and if the mythical M9 can do that, I will buy one.

Jerry
