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!

Canon EOS R5 Infrared Photography Review FAQs
What Is The Canon EOS R5 Infrared Photography Review About?
The review looks at how the Canon EOS R5 performs as an infrared or full-spectrum camera. Kolari frames the test around image results, usability, and common issues compared with the earlier Canon EOS R.
Can The Canon EOS R5 Be Converted To Infrared?
Yes. The article states that the Canon EOS R5 is an incredibly capable mirrorless body and that Kolari can convert it to infrared.
What Issue Does Kolari Test For After Canon R5 Infrared Conversion?
Kolari tests for phase detection sensor lines, a common mirrorless-camera issue after infrared or full-spectrum conversion. These lines can appear across the frame, especially in flat or neutral areas such as skies.
Did The Canon EOS R5 Show Phase Detection Sensor Lines In The Test?
In Kolari’s flat-shot test, the noise pattern looked evenly random, with no evidence of phase detect lines in the full-size shot or crop. The article summarizes that result as “so far, so good.”
Who Wrote The Canon EOS R5 Infrared Review?
The Kolari page lists Pat Nadolski as the author and shows the publication date as October 28, 2020.
