How does the M (Typ 240) compare with Canon 5D MKIII / Nikon 800E?

The longer i'm waiting for the M(TYP 240), the more I hestiate to cancel my preorder. I use to use a Fuji X100, which was recently stolen. So I will need a digital camera of some sort to supplement my film stuff. I know this is extremely self-indulgent, and it is a serious case of G. A.S. For me, It is about finding the right digital camera for me.

For the same price of a M240, I can get a Canon and Nikon with all the lenses i would use for it - with change to spare. On the other hand, I have lenses that I really enjoy using on my M3. (50mm planar, 21, color-skopar, 90mm elmarit (FAT), 135 elemarit Canada)

I occasionally shoot landscapes and urban landscapes (usually with a 4x5). Street / documentary / reportage (what ever you want to call it) with a hasselblad 500C or M3 (depends on my mood) I've been doing more environmental portraits lately with the hasselblad. I occasionally do some work in the studio, but only a few times a year. I also do occasional events (weddings as a third shooter, neighbourhood block parties, etc etc)
I do a bit of everything - and it is all for fun and not commercial.

They are in a whole different class than the M type.

The M is a rangefinder camera that uses Leica M type lenses.

The number of lenses is limited, so if you intend on shooting sports, action or need long lenses, the M will not do the job.

The Nikon D800E and Canon 5D, Mark III cameras are both full frame like the Leica, but can use lenses from fisheye to extreme telephoto (800 mm for instance)

Trying to use mismatched lenses with ANY camera system is false economy. Just buy the system that will do what you want and buy the lenses made for it.

Here is how the sensors compare in the important areas.

There are definitely more versatile choices than the Leica to choose from, and judging by what you already shoot and what you're planning to shoot, I'd say the advantage is for full frame DSLR in everything except the ability to be unobtrusive for street candids.

And yes, Canon and Nikon full frames do have better sensor performance than digital Leicas.
