Digital Camera World Verdict

The Canon EOS Ra is physically identical to the regular EOS R, so we found the same combination of handling likes and dislikes. But this camera is designed for a very specialized field, and some of these quirks hardly matter here. The lens Control ring is a plus point, bing easier to find in darkness than buttons and dials, the cropped 4K video is much less important, and the and lack of in-body image stabilisation doesn't matter in a camera that's going to be used on a tripod. What makes the EOS Ra unique compared to regular cameras is its sensor's extended infra-red sensitivity and increased 30x magnification for pinpoint focus checking.

The Canon EOS Ra is not the first camera modified specifically for astrophotography. Occasionally, camera makers do produce 'astro' versions of their leading cameras, and the EOS R is a good candidate, thanks to its vari-angle screen, mirrorless live view operation and – for those that have the budget – some super-fast RF lenses.
