Document Type and Number:
Japanese Patent JP6533344
Kind Code:
B2
Abstract:
An object of the present invention is to provide a lens apparatus, a camera system, and a lens driving method capable of achieving both a driving range and a resolution of a focus lens. A lens group having a large number of stopable positions due to a high driving resolution, a long driving range, and the like may be set as a first focus lens group. In this case, depending on communication restrictions (command bit length) between a camera body and the lens apparatus, the lens apparatus may not be driven at the desired position and resolution. Therefore, in the lens apparatus according to the first aspect of the present invention, a lens having a small number of stopable positions is driven as a first focus lens group through communication, and the second focus lens group is driven without being restricted by a communication command through calculation in the lens apparatus. Thereby, it is possible to achieve both the driving range and the resolution of the focus lens.
