What the experts say
Digital Camera World thought the EOS R compared well to a DSLR, but it was still way behind other rivals on the market - most notably rivals from Nikon, Panasonic and Sony. It still takes great pictures and has an array of useful features. However 4K video is cropped, there is only one SD slot and in-body image stabilisation has been missed out.
TechRadar sees this as a great mirrorless upgrade to a DSLR but agree rival brands offer more.
A great viewfinder and image quality meant the D750 got the thumbs up from Trusted Reviews. However, the camera size and lack of stabilisation mean it's just not a complete enough camera to win 5 stars.
