Several Canon R5 owners are reporting that some of their images are soft as a result of what seems to be the sensor twisting during an exposure, probably as a result of a bug in the IBIS implementation. Have you noticed this phenomenon?
Canon Rumors was first to report that R5 owners were experiencing issues that appears to be caused when the IBIS is set to “always on”. The first photograph in a sequence seems to “twist” during the exposure as a result of the sensor’s movement and causing a slight motion blur in the corners of the image. Subsequent photographs are then fine.
Only the first image in a sequence appears to be affected. Apparently, if you turn off the camera or review your images, the first photo you then take will suffer the same twist. You can see the bug occurring in the video above from Canon Rumors forum member juanmaasecas.
As Canon News notes, the R5 and the R6 were Canon’s first full frame mirrorless cameras to feature image stabilization and such bugs are not completely unexpected. It is curious, however, that users seem to have been reporting this behavior for several months and yet Canon has not addressed the issue, despite the manufacturer releasing various firmware updates since the camera’s launch.
One user on the Canon Rumors forum reports sending his R5 off for Canon to repair this “wobble” only to be told that it was within “acceptable tolerances”.
