When is rolling shutter an issue using electronic shutter in mirrorless?

Rolling shutter can present challenges when using the electronic shutter in mirrorless cameras, such as the Sony a7 III. This phenomenon primarily affects fast-moving subjects, resulting in distorted images or video artifacts. While it is commonly associated with video, rolling shutter can also occur in still photography, particularly with rapid movement or when panning quickly. Understanding the speed threshold for movement that triggers rolling shutter is essential for capturing sharp, accurate images.
