That's right. I have one, but the rear screen is pretty good and I have not yet used it
I fitted one to the X2 as soon as I took it out of the box. I use it perhaps half the time, maybe a little more. I also have the EVF for it, but haven't really tried it other than to test it. It's quite good (the Leica is the same as the Olympus EVF, I bought the Olympus) and might prove useful at some point, but thus far I haven't seen the need.
Sensible! I also like it simple - so I use few of the more exotic functions some cameras offer. I tend to use my cameras on aperture priority or manual, occasionally program mode, and always shoot raw. I leave the camera on base ISO unless it is necessary to use higher. I don't use video (where offered) or user programmed custom modes, because I forget what I have set and in any event, the camera should be easy enough to use without them (as the DP2M is). It's a camera, for goodness sake, but we are being offered miniature computers in a effort at market differentiation.
Similar here for the most part.
With the GXR, I do use the custom modes ... the camera options for each are set up for the different M-bayonet lenses I use, inject the correct metadata and deal with lens-specific defaults I prefer. But even that remains simple ... I set up the camera for the three lenses I might carry and just set the selector for which lens I have fitted.
I don't change lenses all that often ... I've had the Skopar 28/3.5 on that body for three months now and haven't touched the selector since I put it on. Most I've done is switch the the mode to Manual and back to Aperture AE...
Camera manufacturers try to drive our attention to the camera and what it can do as a means of selling more cameras with better/more/zoomier features.
My preference is cameras that disappear so that I can concentrate on the subject matter. When I want to shoot video, I do. When I want to make stills, I do. I tell the camera what to do, I don't like to have to beg the camera to do what I need when automation gets in the way.
All digital cameras are indeed computational devices, but that doesn't bother me at all. It's whether they work the way I need them to, want them to, that matters.
