We've updated our Canon EOS 5DS/5DS R First Impressions Review to include studio test samples from final production versions of the cameras. The 5DS and 5DS R share a 50MP full-frame CMOS sensor and are identical in every way except for one: the 5DS contains an anti-aliasing filter, while the 5DS R has a self-canceling filter. While we've previously tested a beta version of the 5DS R, we've finally been able to put final production versions of the two cameras through our studio.
