I'll explain one of the reasons I'm willing to drop so much cash on an M9.
Manual focus precision.
I shoot primarily landscape on a 5D-II, and make extensive use of hyperfocus. I've tried novoflex, fotodiox and even cheap adapters, and none provide as accurate a flange to film plane distance as the original mount on my R8. I have to use live view to double check acceptable sharpness and in most cases the lens ends up focused way out of the hyperfocus markings (it doesn't quite reach infinity wide open). I can confidently use hyperfocus on the R8... but it's not digital.
Being able to compose using a bright accessory finder, and use precision hyperfocus I can rely on, I'm hoping will speed up my work in the field.
Obviously polarisers and grad filters are going to be tricky, The Vernier Kenko polariser is likely the way I'll go, with a dual shoe adapter. The bracketing system from the videos/documentation I've read seems to be superior to what is available on the 5D-II, I'm already starting to prefer blending over grad filters for pure control.
Live view for me was a blessing on the 5D-II but only to manual focus wide angles and to achieve hyperfocus. These two things are not a limitation if I'm using a rangefinder with native mounted lenses.
Indeed Doug, I would have considered the DMR if I didn't get my R8 after my 5D-II. I was anticipating an R10 but obviously plans change and I have to change along with them if I want a native mount full frame digital leica.
Also, as a landscape shooter I would have had to purchase the 15mm super-elmarit for my wide shots, which is a big hunk of cash.
