Dual pixel raw allows you to make microadjustments to the focus point of an image provided you use Canon’s DPP SW to process the raw image. It doubles the file size (!) and slows the burst rate substantially - a BIG trade off unless you’re a portarait photographer and need to make minute focusing adjustments after the fact. Experiment and see if you think it’s worth the huge file size, slower processing and substantially reduced burst rate. I didn’t, but others may have a different opinion.
This is true and I want to emphasize that you can only edit or use these dual pixel raw files in the software that comes with your Canon camera called DPP or Digital Photo Professional.
I too did not see any difference and the file size is double as stated by TriX.
