An image capture apparatus on which a lens apparatus is detachably mounted, may include an image capture device, an image-signal processor, a communication unit, and a control unit. The image capture device may generate an image signal obtained by photoelectric conversion of subject light forming an image through a lens of the image capture apparatus. The image-signal processor may carry out image processing on the image signal photo-electrically converted by the image capture device. The communication unit may communicate with the lens apparatus. The control unit may carry out control to receive the correction information for lateral chromatic aberration and/or the correction information for light falloff at edges through the communication unit. The image-signal processor may correct image degradation caused by the aberration of the lens using the correction information for lateral chromatic aberration and/or the correction information for light falloff at edges, which are received through the communication unit.
