(mockup of the UI)
DE: We talked about the USB dock on the Sport lenses, where you can change the focus limit. Other than that, is its main use to adjust the front or back focus of the lens that matches your body?
KY: Yes, it's like a micro-adjustment in the body. But for in-body micro-adjustment, you can only change the focus correction for the entire focusing range. If you are happy with the focus accuracy at infinity, but you are not happy with it at three meters, when you change the settings for three meters then you are off at infinity. The focus position for the lens is not linear. With this software, customers can choose a specific focus distance at which to shift the focus position.
DE: And you can adjust multiple focus distances, and basically change the curve.
KY: Yes, and in the case of zoom lenses, photographers can also choose the focal distance.
DE: For the different focal lengths. Wow.
KY: This is just an example, so this is not the real user interface (referring to image at right). They can choose the focal length, and they can also choose the focusing distance.
DE: That's very sophisticated. There is really nothing else like this.
KY: Micro-adjustment is basically a trial and error technology, so I don't think it's very easy to use. Even micro-adjustment in the camera body, it's not very easy. But we wanted to offer this kind of option to our customers anyway.
