I have both versions of the 75mm for the RZ. It's a big lens, really best used on a tripod. The tilt-shift adapter is well made but somewhat clunky in operation.

The 2 versions of the lens differ - the short barrel one for the TS adapter will allow up to 10mm shift plus 10 or 15 deg of tilt. The shift-only version of the 75 will shift up to 20mm. So, there is some difference depending on what you need/want. As far as sharpness, it's a nice lens - really quite good as are almost all of the RZ lenses - nothing to be concerned about from that perspective.

That said, given the limited amount of shift, the size/weight, etc. - it would likely be easier to use the 4x5 you have, or a different camera rather than get into the RZ just for this solution. There's a lot better choices out there, I think, if you are looking for something to shoot 75mm with significant shift. Any rollfilm back (Horseman for example) on a graflok-equipped camera (say, a Graphic of some type?) will be easier, cheaper, and more functional I think. An RB/RZ with the 75 shift really is a BIG, HEAVY camera - it's actually heavier than my Horseman VH with rollholder and 75/6.8 Grandagon. So long as your subjects sit still and you don't mind GG focusing with a loupe and swapping the rollholder and GG all the time, the VH/Grandagon combination is rugged, practical and affordable. If you prefer not to have to keep swapping the back and don't mind shooting only 6x7, you can also keep an eye out for the 2x3 version of the Linhof Rapid Rollex, which works fine as a slide-in on the VH.

Thanks for the comments. I just found out that pentax also made a 75mm shift lens for the pentax 67 (II). The camera and lens should be definitely smaller and lighter than the mamiya.
