NA-5DSR Housing for Canon EOS 5DS/5DSR/5DMKIII CamerasThe Canon 5DS and 5DS R raised the resolution bar to a new high for the digital SLR with a 50. 2MP sensor. Taking advantage of this high level of resolution underwater requires an equally impressive housing. The NA 5DSR not only works with the 5DS and 5DS R, it also works with the 5DMKIII.
