Well, I can tell you you can use your M lens on an *istD. There is no metering because the camera has no mechanical coupling to tell it what aperture is set on the lens. But if you are willing to use your hand-held meter (or you could use trial and error, checking it with the LED image) it works fine. All you have to do is set the custom funtion that allows shutter release out of A mode. The default is set so idiots can not mess up by making a non-metered exposure. It also worked in program mode with my 3rd party KA lens, no problem. The *istD is a very neat camera. It has the best viewfinder I have seen in a DSLR (I have handled the D100, S2, D60, & EOS1D), it is about the same apparent size and brightness as the MZ series 35mm cameras (remember the sensor is smaller than 35mm so the viewfinder needs higher magnification to give the same apparent size). The prototype available for us to play with has a problem with power management. That will be fixed in the production cameras. I think it is the best of the sub $2000 DSLRs. At $1699 I think they are going to sell faster than they can make them.
I am home tonight from GFM because my air mattress suffered blowout last night. Living only 30 minutes away I decided I liked the idea of a soft bed and a hot shower better than the hard cold floor of my Blazer. Got to get up early and return in the morning so I don't miss anything. I hear all you folks to the north have been having quite an adventure.
