I realize digital back sales are driving the sale of cameras, lenses + accessories, but I think it's just weird to see anything but a Rollei logo on the camera. It's a Rollei, so call it a Rollei. I'd cover with black tape any other logo to avoid having to explain "It's really a Rollei camera, manufactured by Jenoptik, but labeled a Leaf, PhaseOne, or Sinar.
just a little precision, but important: it is a "Jenoptik" camera, manufactured by "Franke & Heidecke" (not Rollei), and labeled Leaf and Sinar. That's the right way to present it.
