Canon or Nikon 35mm sensor camera. The Sony A7 has already made you highlight a physical balance issue. If you shoot indoors or in low-light often then Nikon plus top quality Nikon lenses is what you ought to get as their sensor is more capable.
Remember any 35mm sensor camera is going to really show-up the image quality defects from poor quality lenses, and getting good telephoto zooms at that level is ultra-expensive.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
