Metz MECABLITZ 64 AF-1 digital Pentax - Manual (Page 211)

Automatic switching to the flash sync speed fails to occur.
• The camera has a between-the-lens shutter (as do most compact
cameras), Switching to sync speed is therefore unnecessary.
• The camera operates with high-speed synchronisation HSS (came-
ra settings). Switching to sync speed does not occur in the pro-
cess.
• The camera operates with shutter speeds that are slower than the
flash sync speed. Depending on the camera mode, there is no
switch to flash sync speed (see the camera’s operating instructi-
ons).
The shots are too dark.
• The subject is beyond the range of the flash unit.
Note: Using bounce flash reduces the range of the flash unit.
• The subject contains very bright or highly reflective areas. The
metering system of the camera or flash unit is deceived as a
result. Set a positive manual flash exposure correction,
e.g., +1 EV.
The shots are too bright.
• In close-up shots, overexposure (shots that are too bright) may
result if the shutter speed is faster than the flash sync speed.
The aperture (f-stop) cannot be adjusted on the flash unit.
• There is an exchange of digital data between the flash unit and
camera.
Adjustment of the aperture is not possible!
