Abstract:
1. An image-pickup system which includes an image-pickup apparatus and a lens apparatus that is removably mounted on the image-pickup apparatus, comprising: a first memory which is provided in the image-pickup apparatus, and stores first identification information unique to a combination of the image-pickup apparatus and a certain lens apparatus, and stores data for adjusting lens position associated with the first identification information; a second memory which is provided in the lens apparatus and stores second identification information unique to the lens apparatus; and a comparator, a generator, and a controller, which are provided in the image-pickup apparatus, wherein the comparator compares the first identification information stored in the first memory with the second identification information stored in the second memory, wherein when the comparison by the comparator results that the first identification information does not correspond to the second identification information, the generator generates third identification information associated with the lens apparatus, and the controller stores the third identification information in the first memory, wherein the third identification information is different from the first and second identification information, and wherein the controller obtains data for adjusting lens position of the lens apparatus and stores the data for adjusting lens position associated with the third identification information in the first memory.
