Welcome to Rollei-land. I've been using the system since about 1992, and have owned each of those lenses, although with different experience levels. Much appreciate the system, and currently use the lenses with the later Hy6 body.
I have used a number of lenses for repro work, as they are all quite good. The 90 is exceptionally sharp, and it is real crisp. Eric Hiss (Rolleiflex USA - check out his website, full of good info) is quite fond of this lens and has taken some very sharp images with it, including multishot. I did a test comparing it with a Rodie 90 HR lens (one generation back) and found it either comparable or superior. All good for this lens.
Very fond of the leaf shutter. Use it all the time, with the easy mirror lockup. For walk around, one can use a monopod, compose, hold steady and just flick the mirror up and shoot. Got some nice shots in dimmer light with that, shooting the 60 reasonably controlled to 1/40, and in extreme, to 1/20 sec.
On each of the lenses -
40 3.5 - this is a nice compact Schneider lens, and generally decent. It is, however, the only Schneider lens for the Rollei that shows a bit of softness on the edges. I prefer tech camera lens for the wides, but this is a good lens with that one caveat.
60 3.5 - if this is the Curtagon, favorite lens of the group. Don't know why, but it is sharp, has warm, a general rendering that is IMHO superior to any other lens owned. Don't let this one go. Haven't used it for copy work tho.
90 f4 - the macro of the group. Super sharp. long focus throw, I don't care for it for walk around, somehow finding myself always short of DOF. Prefer the 80 2.8 AF, with optional 1.4 TX for the general use instead.
110 f2 - much loved lens by others, but I didn't fall for it. Too heavy for walk around. The best Zeiss in the Rollei family (the other ones are not as good as the Schneiders).
180 2.8 - very good lens, no flaws, just not light. Much liked for portrait work. Use with the 1.4 TX, and get a 250 f4, with no loss of quality. However, I prefer the smaller 150 telexenar.
My walk around kit is typically the 60mm, or if there is room, I'll add the 80 with the 1.4TX, or just the 150 Telexenar.
All of these lenses will do fine on digital backs - I've seen Eric's work on the 80mb back, I use a Leaf 33mp back, and really have no complaints. For walk around, I'd base your work on the 60 Curtagon, and use the others as needed. Its easy enough to add the 80 2.8 if you want it later. Or the 150.
Enjoy the system. Not too sure about whether this makes much sense to add on the Sony FF body, but you'll figure that out. These are fine lenses, solid as rocks.
