I have been an amateur photographer for many years and tend to use the 5D Mk2 in much the same way as I used film cameras - taking photos of subjects that interest me in a methodical fashion and taking as much time as needed for composition. I am very happy with the camera and the results I get from it. Taking movies is of no interest to me. I have prime and zoom lenses covering 17mm through to 400mm but find the vast majority of my photos are taken with a 40mm f2.8 pancake and a 85mm f1.8. After an absence of about two years, I recently began visiting photo forums again - and what depressing reading. The clear message is that I am using an obsolete piece of technology clearly bested by any full frame camera now on the market, DSLR or mirrorless, especially those made in the last two years. I know some of this may be marketing hype, but equally I don't want to be happy in my ignorance if technology has made advances that should make me consider selling my 5D. Any advice from members who have made the move from the 5DMk 2 would be appreciated.
