Phase One has you covered.
These are medium-format digital cameras. Though I can’t find if they support perspective shifting accessories.
I can’t find pricing on the camera (in 2010, they $55,000. No, not a typo.) The new lenses come in at $7000 for 150mm and $6000 for the 45 mm option.
The photos at the site are stunning. To say the least. 100 megapixels is approaching the definition of slow film.
Used gear starts at 10 grand. Still out of my price range.
