Just arrived from Germany: evaluation units of the Hartblei 40mm f/4, 80mm f/2.8 and 120mm f/4 Superrotator tilt/shift lenses, utilizing Zeiss medium format optics in Hartblei-engineered barrels. Marvels of engineering indeed, and built as solidly as anything you’ll find.
It will take some time to familiarize myself with these unusual offerings, with coverage to follow in DAP. Preliminary impressions are that all the lenses have unusually pleasing bokeh (out of focus blur), with the 120/4 offering especially nice results, due in part (perhaps) to its 12-bladed aperture.
The Hartblei offerings are available in a variety of mounts, including Canon, Nikon and others.
