As I work through the 80D evaluation, testing this camera's Anti-Flicker Mode was on my to-do list. This technology is such a game-changer for indoor and after-dark outdoor action that I felt compelled to share the test results from the latest EOS model to feature this capability.
The top set of images show consecutive frames from an 80D 7 fps burst using a 1/1000 sec shutter speed under fluorescent lights with no flicker avoidance in use. The uneven brightness and white balance shown in these photos represents a daunting post processing challenge.
The best solution to the light flicker problem is Canon's Anti-Flicker Mode, available in many of Canon's EOS DSLR cameras, starting with the 7D Mark II. The bottom 8 images show the results of the enabling the Anti-Flicker Mode. My results from shooting an indoor soccer match with the 80D were similarly excellent.
