ADVANCED OPERATION FOR THE BUILT-IN FLASH

F, FA and FA J Lenses Compatibility with the Built-in Flash

If an FA J, F or FA lens incompatible with the built-in flash is used, pressing the shutter release button halfway down causes

rapid blinking of in the viewfinder and on the LCD panel as a warning.

If you take a flash picture with an incompatible lens, the corner of the picture may look dark or there may be a dark, semi-circular area on the lower part of the picture.

= compatible

= Vignetting will occur under the usage conditions = incompatible because of vignetting
