All Rodenstocks, have a IC edge indicator built in, at least all of mine do. Maybe something they finally decided to quit using. But with any current Rodenstock, as soon as near the outer edge of the IC you hit the indicator with a hard black vignette. With some Rodenstocks, before you get to the black edge you pick up a reciprocal white edge, easily done on the 28HR.
The longer lenses have larger IC's so they may benefit from this new camera, but as pointed out at huge cost in glass.
Makes just as much sense to use modern software, and a 40 HR-W or similar lens, in portrait mode, panning across a scene, then stitch together later on. Sure nothing beats shifting the back, no parallax, but most outdoor scenes easily work together with the advanced in software over the past 3 years.
Also the longer glass with have more DOF issues, so depending on your scene location, you may need multiple shots with focus bracketing to get the nearest most object in good focus. But they also have the largest IC's for cameras like this that can take advantage of them.
