For years, a piece of advice has been passed down among photographers: always turn off your in-body image stabilization (IBIS) when your camera is mounted on a tripod. The reasoning seemed sound enough. 

 

The IBIS system, designed to counteract micro-movements from handheld shooting, might "hunt" for nonexistent shake when perfectly still, potentially introducing its own vibrations and leading to softer images. 

 

This has become a widely accepted truth, but is it actually true? One photographer, Mark Denney, decided to put this long-standing myth to the test with some surprising results. His findings might change the way you approach shooting with a tripod forever.
