Yes same lens the 645 size. Not 100% sure if OK with the Proline. My Proline needs a service. I did put it on the Proline but bad vignetting and also bad tilt. Put it on the Microline and viola it was fine as is. It might be fine with some careful mounting so no tilt (I added some support to under the end of the lens or perhaps a mounting ring). What is cool about the lens is its double ED like an FSQ but not the correction of the FSQ nor the supreme lens accuracy. But its a good setup.
The 6x7 version would be the one for the Proline its just that bit wider. I have the 55, 75, 165 and 300mm 6 x 7. There is an ED version for the 300 and 400mm versions. The 300mm 6 x 7 is the one Marco Lorenzi used on his Proline. The non ED version is cheap and would be fine for narrowband but chromatic aberration for colour imaging. Again tilt is the issue as its long and heavy.
The 6 x 7 version is quite expensive still and not that common. But I suppose as its meant to be used with medium format 60 x 70mm its corrected circle must be at least 70mm.
