Hello, I will be purchasing an RZ67 Pro ii Medium Format camera soon, now by no means is this camera "old old" but it certainly has been out of production for some time now. I recently read a thread on photo.net about the risk of purchasing old film cameras left in original packaging (untouched). They state, no use over a long period of time can run the risk of the camera being non operational due to lack of lubrication. If this is true would it be smartest to purchase a used model, or does this not apply to the RZ67? Hopefully someone can educate me here Cheers.
