Thanks for your very interesting contribution .
I can only agree to what you say , knowing that your statments come from the absolute professional corner . All your investments must make money and an emotional bond is not essential (but might still exist) .
That is of course very different for a semi professional or even a strict amateur photographer . The investment here must not neccessarily make money . The investment first of all must produce joy and fun and pride .
Not even talking about the other species , the collectors .
I never sold any of my gear , but I "tease" all my beauties and take very much care of them . I have a very strong emotional bond to my gear ,
even to my former trouble maker , the CFV-16 . I have invested not only money , but also plenty of lifeblood .
So it comes , that from time to time I also use a 6x6 camera from the mid 1950ies and have fun with it .
