For these special digital single-lens reflex camera lenses, the image circle has been designed to match the image elements which correspond to the APS-C size. The original technology gathered during the development of the SD series of digital singe-lens reflex cameras has been used to realize optical abilities most suitable for digital images. This high-performance lens series combines the technologies and know-how for lens power arrangement, coating design, etc., accumulated during long years of developing interchangeable lenses for single-lens reflex cameras, with up-to-date digital image technology. Reduction of the image circle diameter makes it possible to reduce the size and the weight of the lens, and contributes widely to the handling characteristics at the time of taking pictures.
* Use is not possible for digital single-lens reflex cameras with image elements larger than the APS-C equivalent size, 35 mm single-lens reflex cameras, and APS film single-lens reflex cameras. In case of such use, vignetting occurs on the screen and in the resulting images.
