My opinion is based on what I shoot and how I like to shoot it. So, it's not a good idea to base your gear-buying decision on someone else's opinion. The A7 is a great camera if you don't mind having a slow-focusing system, one memory card slot, few native lenses where the best are extremely expensive and not as good as what Canon or Nikon put out.
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.
