The Canon EOS R5 Infrared Photography Review

Rarely is a new camera release so rich with expectations and controversy. Regardless of how we may feel about the 8K video performance, the Canon EOS R5 is an incredibly capable mirrorless body. And the best news is we can convert it to infrared. So, how does one of the most powerful mirrorless camera bodies released to date perform in the infrared spectrum? Our infrared photography testing involves going over the images, user friendliness, and common issues to see whether or not the EOS R5 makes just as good of a full-spectrum or infrared camera as its predecessor, the EOS R.

Phase Detection Sensor Lines

Mirrorless cameras in particular often have a common issue after an infrared or full-spectrum conversion because of the direct sensor based phase detect focus system. This manifests as horizontal lines across the entire frame. They’re not always visible, though they tend to appear in flat or neutral areas in the frame such as the sky in a landscape shot. We can test for this by shooting against a flat backdrop, crop in, and boost contrast to see what shows up.

Here on the left we have the full size flat shot, and on the right is the crop in with ol’ Ctrl+Shift+L in Photoshop. In both shots the noise patterning looking evenly random with no evidence of phase detect lines in either shot. So far, so good!
