Hi All - Just received my Canon 5DS R and so went to my local beach to test it out (see below for a couple of shots) - First thoughts are amazing. Massive difference in quality compared to my previous 5D Mk II. A lot of the functions are the same but there are some major differences in my view, for example, cropped view, mirror / shutter delay and the quietness of the shutter. The camera back display is a massive improvement and the option of customising your own settings is a huge benefit. I have seen reviews stating its low ISO, FPS and lack of improved video but this camera along with the 5DS are not meant to be a high FPS sports camera or low light / video camera. I have only used my Mk II a few times for video so I am more than happy with my purchase. Well done Canon :)
