After entering the custom settings into the camera I now have a strange problem. Hope I am just missing something obvious but I have not been able to correct it.
When in the Landscape Bank the shutter fires as if it was set to 1/4s. It does it every time even if the shutter is set to 1600. The other three banks are normal. I have rechecked all settings and can find nothing odd. This only occurred after entering the custom settings.
