Focus Camera has the Canon EOS R Mirrorless Camera in stock with free one-day shipping and is throwing in a free Sony SF-G Series 64GB Class 10 UHS-II SDXC memory card (over $100.00 value) as well as a Canon Mount Adapter EF-EOS R ($99.00 value).
As the long-awaited Canon full frame mirrorless camera line is beginning to fill out, the first two models are worth comparing.

The EOS R is a higher-end model and that shows very strongly in its list of advantages.
However, the first three RP advantages are very significant ones.
Those on a tight budget are going to be favoring the RP.
While the EOS R is itself a relatively small and light camera, the RP easily bests it in these categories and those traveling, hiking, etc. may be willing to forgo the R's benefits to also give up some size and weight.
