User manual METZ MECABLITZ 44 AF-4 M

[. . . ] Although our designers have attached great importance to making the operation of the flash unit as simple as possible, the cameras with which it will eventually be used often offer a great diversity of capabilities. please also fold open the illustrated page at the end of these instructions. The 28 AF-3 C digital flash unit is only suitable for Canon cameras with TTL flash control or E-TTL flash control. The 28 AF-3 M digital flash unit is only suitable for Minolta-Dynax / Maxxum cameras with TTL flash control and Minolta Dimage digital cameras with preflash metering or ADI flash control. [. . . ]  Ensure that the contre-jour light source does Not shine directly into the lens as this will mislead the camera's metering system!There is no setting made or indication given on the flash unit for this function. Other flash modes such as normal TTL or Manual M or MLo are not possible in these camera modes.  With some cameras the E-TTL mode is automatically activated on the flash unit when the green full auto mode or a programmed image control mode is selected. fE flash exposure storage Some Canon cameras offer the possibility of FE flash exposure storage. FE flash exposure storage in E-TTL mode permits the amount of light required for the subsequent shot to be determined and stored prior to exposure. This can be expedient when flash exposure has to be adapted to specific details that may not necessarily be identical with the main subject. Focus the camera's AF sensor metering area on the zone whose flash exposure is to be predetermined. When the FE button on the camera is actuated (the designation may vary with individual The electronic measuring circuit inside the camera assesses the reflected light of the FE test flash to determine the light output required for the subsequent exposure. The main subject can thereafter be focused with the AF sensor metering area of the camera. When the shutter release is pressed the picture will be exposed with the previously determined light output. If a picture is shot before flash readiness is signalled, then the flash unit will not be triggered so that the exposure may be incorrect if the camera has Changed over to flash sync speed in the meantime (see 5. There is no correct exposure confirmation given in the manual modes M or MLo. To offset this effect a correction value can be set on some cameras to manually match the TTL flash exposure to the photographic situation. The extent of correction depends on the contrast prevailing between subject and background. A dark subject in front of a bright background: Positive correction value. Light subject in front of a dark background: Negative correction value. Normal synchronisation In normal synchronisation the flash unit is triggered at the beginning of the shutter time (1st curtain synchronisation). normal synchronisation is the standard mode on all cameras , and is suitable for most flash shots. Depending upon the given mode, the camera is changed over to the camera's sync speed, the customary ones being between 1/30th sec. No settings have to be made on the flash unit, nor is there any display for this mode. Second-curtain synchronisation is particularly advantageous when using slow shutter speeds (slower than 1/30 s) or when shooting moving objects that have their own source of light. [. . . ] The red-eye reduction facility brings about a significant improvement in this respect. When this function is used, the flash unit will fire one or more weakly visible preflashes (depending on the 99 These preflashes induce the pupils to close down, thereby diminishing the red-eye effect. There is no setting made on the flash unit, nor an information given on the flash unit's display. If the ambient light is sufficient for an exposure in normal mode, then the camera will prevent the flash unit from firing flashes. [. . . ]
