Sony α SLT-A58 Instruction Manual page 221

Notes
• When the distance between the subject and the external flash (sold separately)
cannot be determined (wireless flash shooting using an external flash (sold
separately), shooting with an off-camera flash using a cable, shooting with a macro
twin flash, etc.), the camera automatically selects [Pre-flash TTL].
• Select [Pre-flash TTL] in the following cases, as the camera cannot perform flash
compensation with [ADI flash].
– A wide panel is attached to the HVL-F36AM flash.
– A diffuser is used for flash shooting.
– A filter with an exposure factor, such as an ND filter, is used.
– A close-up lens is used.
• ADI flash is only available in combination with a lens that is provided with a
distance encoder. To determine if the lens is equipped with a distance encoder, refer
to the operating instructions supplied with the lens.
• [Flash control] cannot be set when the exposure mode is set to [Sweep Panorama] or
[Night Scene]/[Hand-held Twilight] in [Scene Selection].
