If you decide to use a tripod. monopod, beanbag, or other stabilization device, rather than hand-holding the camera, make sure the Image stabilization (steadicam) feature of your camera is turned off.
This feature is generally a mathematical algorithm inside the camera that tells the camera how much the average human being shakes while breathing, heartbeat, etc. and it compensates for that tiny amount of shake.
When the function is turned on, and a human isn’t holding the camera, it applies these same adjustments anyway making your clear pictures slightly blurry.
As there are a ton of camera types, makes and models out there, just to be safe and get the most out of your pictures, turn this function off when not holding the camera.
