I presume the glass is different in these MF units? The Tilt mechanism in these lenses is totally different, but the rotation of the tilt & shift mechanism and the shift mechanism could be identical.
The Super Rotator concept may be executed with some differences in the smaller lens, but it's still the same idea. Note that Hartblei produces lenses that have tilt and shift without the ability to rotate each to different axes, and also just plain shift lenses.
The Hartblei 45mm tilt/shift lens uses the same optical elements as the Arsat 45mm/3.5 (formerly the Mir-26), and the 65 uses the same elements as the Mir 38. Neither were designed for movements, and neither really have the coverage to provide movements without some compromises.
Here's my article on the 45mm Hartblei PCS lens:
The Arsat 55mm/4.5 shift lens, on the other hand, was designed for movements and is reportedly quite excellent even at 12mm of shift. I don't have one. That lens is not available with a tilting mount.
Of course, all of these, when adapted to small format, will have an abundance of coverage. The 80mm tilt-shift lens is just a standard Arsat 80mm normal lens with Hartblei coatings mounted in a Hartblei barrel.
Just so you know, the name Hartblei is not exactly precise. Hartblei is reportedly owned by Sergey Naumenko whose operate is in Kiev, but you'll find that the Hartblei web page is operated (with or without cooperation from Naumenko, depending on who you ask) by Alexander Pissarenko who resides in Prague. I have speculated, in the absence of any facts, that the technicians who do work for Hartblei are former (or possibly even current) Zavod Arsenal technicians who do piece work for Hartblei, Arax, and others. Pissarenko at one time operated Kalimex SRO in Prague, and ran into, shall we say, perceived customer service issues. The establishment of the Hartblei name was partly to distance the operation from the difficulties caused by the Kalimex association.
Mikhail Fourman, who operates Kiev Camera, has always wanted Hartblei to concentrate on lenses, including lenses with mounts for mainstream medium-format cameras, as being a better use of their resources than some of the camera upgrades they have been doing. But Hartblei upgrades Arsenal's Kiev 88CM for Kiev Camera, just as Arax upgrades cameras for their own sale. Araxfoto is owned by Gevorg Vartanyan in Kiev.
By the way, Reichmann's Luminous Landscape lost a lot of its former high credibility with me over his test of Arsat-based lenses. Some of the tests (I recall it being of the outstanding Arsat 30mm fisheye) showed obvious focusing errors, yet Reichmann insisted those did not change the results when challenged by members of the Kiev Report, many of whom have done their own testing even more rigorously than did Reichmann. I find it more difficult to trust any of his results since that time.
