Well first of all, a cannon shoots cannon balls. When it comes to the cameras used mostly by the pros, most photographers who buy their own cameras buy Nikon's and many of those who are supplied their cameras by their employers use Canon cameras. You can use your own imagination to figure that out.
Both cameras have huge numbers of lenses within their systems. As a general rule, Nikon camera sensors tend to introduce new sensors with each iteration of their cameras, thus the sensor performance tends to increase over time. (See the link below) Some say that Canon digital SLR cameras with a video feature perform better when shooting video, but I have to tell you, my Nikon D800e shoots amazing RAW video files.
In both cases, you need to hang another $1,500 to $2,000 in accessories to make them into a viable video camera. Even then you will not have many of the features a true video camera has, namely 3-CCDs or a 3MOS sensor, Genlock, XLR microphone inputs, 24 bit/48 kHz/4 channel audio recording with phantom +48 V , SMPTE time code read/write and many other features used by videographers.
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.
