Canon announce their new 5D Mark IV camera today and I have decided to add it to my kit. Fortunately, I was able to return my recently acquired Canon 5DS (replacement for one of my cameras stolen in Costa Rica) for full credit towards the new model which has exactly the same price point.  Even though the 5DS is a 50 MPixel body compared to 30 MPixel 5DM4, the later has better dynamic range, better low light performance, a more balanced feature set and is a better fit with my needs. I hope to have the new camera by mid September.
