18-200mm F/3.5-6.3 Di III VC (Model B011) Precautions when using the supplied flash
When using the flash supplied with the camera, adverse photographic phenomena such as corner illumination fall-off or vignetting at the bottom part of the image may be observed, especially at wide angle and at close range. This is due to the inherent limitation of the coverage of the supplied flash, and/or the relative position of the flash to the edge of the lens barrel which causes shadows on the image. We recommend removing the lenshood when using the supplied flash.
