Seems I hit into a hornet's nest. If I insulted some people that was not my intention. I don't want to be cleverer, everybody shall use features of his/her camera that are helpful.
But apparently nobody noticed I put this in Philosophy of Photography, not in a technical category. My point is not if the menue of my camera is complicated; actually I used the D700 for years as I did and obviously, turning it back into a kind of 1980s DSLR worked well.
My point was only if someone agrees that being limited in what I can technically shoot may actually improve the results. Because I may be more focused on the kind of pictures I like.
To be honest I am not yet sure if that is so but I will try to find out.
