![]() ![]() Close-ups of sub-frames from this shoot with the R5, and also with the R6 and Ra, are used throughout the review. This is a stack of 12 x 5-minute exposures with a Sharpstar 94EDPH refractor at f/4.5 and the Canon R5 at ISO 800, taken as a test of the R5 for deep-sky imaging. It was not so well suited to shooting videos of auroras. Its 8K video capability has a place in shooting the Moon, Sun and solar eclipses. The Canon R5 proved to be surprisingly low in noise, and has worked very well for nightscape, lunar and deep-sky photography (as shown below), where its high resolution does produce a noticeable improvement to image detail, with minimal penalty from higher noise. The Canon R5 uses a full-frame sensor offering 45 megapixels, producing images with 8192 x 5464 pixels, and making 8K video possible. Patience! Thanks!Īll images are © 2022 by Alan Dyer/. The blog contains a lot of high-res images, so they may take a while to all load. NOTE: CLICK orTAP on any image to bring it up full screen for closer inspection. Is the higher noise noticeable? If so, does that make the R5 less than ideal for astrophotography? To find out, I tested an R5 purchased locally in Calgary from The Camera Store in May 2022. Each pixel is only 4.4 microns across, providing higher resolution but risking more noise. Where the R6 has a modest 20-megapixel sensor with relatively large 6.6-micron pixels, the R5 is (at present) Canon’s highest megapixel camera, with 45 megapixels. In a sequel to my popular post from September 2021 where I reviewed the Canon R6 mirrorless camera, here is a similar test of its higher-megapixel companion, the Canon R5. In a format similar to my other popular camera tests, I put the 45-megapixel Canon R5 mirrorless camera through its paces for the demands of astrophotography.
