Which Canon DSLR should you buy? Cam Noob Clara had this question, and in the end, based on her needs and budget, we decided that the 6D was the best choice. The 6D Mark II had just been released, and the price for the 6D + 24-105 f/4 V1 +1 Year of Lightroom/Photoshop was an excellent deal.
Here is a comparison chart for Canon DSLR’s (as of July 2017) for you to either choose or at least limit your choices. For example, if 4K video is a must, you have 2 choices: the 5D Mark IV or the IDx Mark II.
