I do not use the DSLR version of the M-Line Two, so I can't tell you anything specific about these issues. I would recommend to get directly in touch with Martin Vogt at Arca Swiss who knows best about any restrictions regarding movements / lenses, etc.
As far as I can tell the M-Line Two is a beast with regards precision. Doing this step moved my requirements for precise accessories (if you can call a tripod head an accessory) far beyond everything I expected. I already used a Gitzo 3540 XLS together with an Arca Swiss Monoball Z1 DP, now with an Arca Swiss Cube C1.
I could not do much testing, as I am one of these guys affected by the Leaf / PhaseOne fairy-tale, but this is a whole story of its own. I ordered an Aptus II-7 approx. 2 months ago, just right in time before all this mess started. Still on hold. Occasionally I got a rental back from Leaf Germany, who are more than helpful. If I find the time I can post sample images, maybe by the end of the week. The shortest lens I used is the Rodenstock 35mm. So far I do not have any experience with 28, 24 or even 23mm. Maybe in the near future, we will see.
To the DSLR users who consider using this camera together with their DSLR bodies – basically I had the same approach, but after re-thinking this, it just did not make sense to me. Taking photos with the M-Line Two and a digital back has slowed me down compared to the 1 Ds MKII, but has also reduced rubbish. Personal opinion and experience, nothing else.
