The figures in parentheses show the actual aperture values at 60mm(Telephoto) for the aperture values at 30mm{\A/ide Angie).
When you set your desired aperture(aperture-priority AE), the quantity of light of the flash changes with the shooting distance. When the
exposure mode is set to ''P"(program AE), the aperture changes with the shooting distance(flashmatic method).
When you take flash pictures, it is recommended to set the exposure mode to "P". If you stop down the
aperture, the flash effective range becomes shorter. Also, piease be careful that if you take a photograph at
the telephoto side, the flash effective range becomes shorter.
•
If you want to take pictures with flash at longer distances than the effective range of the built-in flash, use an external
clip-on flash with the aid of the CONTAX Flash Adapter SA-1 (optional accessory).
