Interesting review. The Rm3d takes some novel approaches to aid focusing with the E-module, but it still seems pretty kludgy (especially using ultrasonic distance measurement instead of laser). I definitely agree with Bernard that LiveView is really the ultimate solution, it's just a matter of when the MF guys will be able to deliver it. Until you've used LiveView on the D3/D3x you just can't imagine how good it is for critical focusing with both autofocus and manual focus lenses. In fact I'm thinking that the F-Line 2 plus a D3x would be a better solution for me than the Rm3d with entry-level digital back for this very reason. I just wish there was more info available on the F-Line 2, particularly any limitations/gotchas when using the DSLR version (lens compatibility, etc).
