Thanks for the welcome.
Yes, adjusting the position of the focus knob infinity stop relative to the lens board will indeed affect both lenses. Which is part of the reason why the adjustment procedure consists in the first instance of setting the taking lens correctly via the infinity stop, and then dialling the viewing lens in to match it. If adjustment to the taking lens is needed, even if the viewing lens was well adjusted beforehand, it would subsequently be off and have to be re-adjusted, anyway.
There are usually one or more longer shims under each side of the lens board to set the parallelism of each side and usually a smaller shim on top of that to fine tune each corner. These should not need to be touched to set the infinity focus correctly if the parallelism is OK. The procedure would consist of adjusting the infinity stop as outlined previously. If the lens board is not parallel to the film rails, the shims may need adjustment, particularly if the Rollei has been tampered with. But only after checking the rails that the "carriage" for the lens board slides in for wear, looseness, and also the focus cam followers. Wear in these areas often leads to misalignment that may be adjusted out. If after correcting this the parallelism is incorrect, it will be necessary to reshim the board to true it. Instead of shims, F models feature a slotted adjuster and lock nut on each corner. Adjustment of these achieves the same effect as shimming previous models.
Unfortunately, these cameras are of the age now that, no matter how superbly they were manufactured, they are often in need of some wear adjustment. A Rolleicord Va arrived a couple of weeks ago with so much slop in the system the whole lens board literally rattles around in the camera body (how anyone would make anything approaching a sharp image with it in that condition, I will never know). We're talking about three or four millimetres of play. It remains to be seen if that will be salvageble or whether it will be destined to be a parts camera. My Tele, on the other hand, seems to be in good overall order, but the weight of those long lenses has clearly put more strain and hence, promoted more wear on the cam followers, and I suspect this is typical following substantial use for that model.
My own general observations based on the 15 or so Rolleis I've handled in the last couple of years or so are that good, clean, low use cameras are a little harder to source (at least, on line). I had quite a good run early on but many of the Rolleis I have acquired in the last year have needed a lot more than a shutter clean and focus adjustment to set them right. Focus misalignments seem to be more common. Perhaps I've simply been unlucky, but I do wonder if many of the really good examples have already found new homes and that this is being reflected in the less than perfect condition of more recent offerings. Of course I'm in Australia, but I do buy from overseas, too.
