A flare appears on part of the image when I use a flash.

Depending upon the scene where the image is being recorded, the light from the lower part of the wide panel may enter directly into the lens when the SEL16F28 Fixed Focal Length lens is attached to the camera. This may cause flares to appear on the image.

You can reduce the flare effect on the image by blocking the light from the lower part of the wide panel. The easiest way to do this is to cover the upper part of the lens with your hand.
