An imaging apparatus comprising: an imaging sensor that captures an object image formed through an interchangeable lens, to generate image data; a driver that performs image blur correction by moving the imaging sensor in a plane perpendicular to an optical axis; a controller that causes the driver to move the imaging sensor within a range of a changed movable amount; characterized by: an operation unit that accepts a user operation for changing a movable amount of the imaging sensor during image blur correction; and a display unit that displays an image, wherein the controller causes the driver to move the imaging sensor maximally in a diagonal direction of the imaging sensor with a changed movable amount with a sensor reference position as a reference, when a user operation for changing a movable amount on the operation unit is performed, and causes the display unit to display a live view image indicated by image data generated by the imaging sensor, at a position moved maximally, wherein the operation unit is configured with a user interface that allows the user changing the movable amount in order to avoid a vignetting effect when moving the imaging sensor diagonally. an imaging sensor that captures an object image formed through an interchangeable lens, to generate image data; a driver that performs image blur correction by moving the imaging sensor in a plane perpendicular to an optical axis; a controller that causes the driver to move the imaging sensor within a range of a changed movable amount; characterized by: an operation unit that accepts a user operation for changing a movable amount of the imaging sensor during image blur correction; and a display unit that displays an image, wherein the controller causes the driver to move the imaging sensor maximally in a diagonal direction of the imaging sensor with a changed movable amount with a sensor reference position as a reference, when a user operation for changing a movable amount on the operation unit is performed, and causes the display unit to display a live view image indicated by image data generated by the imaging sensor, at a position moved maximally, wherein the operation unit is configured with a user interface that allows the user changing the movable amount in order to avoid a vignetting effect when moving the imaging sensor diagonally. an operation unit that accepts a user operation for changing a movable amount of the imaging sensor during image blur correction; and a display unit that displays an image, wherein the controller causes the driver to move the imaging sensor maximally in a diagonal direction of the imaging sensor with a changed movable amount with a sensor reference position as a reference, when a user operation for changing a movable amount on the operation unit is performed, and causes the display unit to display a live view image indicated by image data generated by the imaging sensor, at a position moved maximally, wherein causes the driver to move the imaging sensor maximally in a diagonal direction of the imaging sensor with a changed movable amount with a sensor reference position as a reference, when a user operation for changing a movable amount on the operation unit is performed, and causes the display unit to display a live view image indicated by image data generated by the imaging sensor, at a position moved maximally, wherein the operation unit is configured with a user interface that allows the user changing the movable amount in order to avoid a vignetting effect when moving the imaging sensor diagonally.
