Or:
•Briefly turn off the mecablitz by its main switch. When the flash unit is turned on again the mecablitz display will indicate „Auto Zoom“.
5.6.3 Extended zoom mode
The extended zoom mode (Ex) reduces the focal length setting of the meca- blitz by one step compared with the focal length of the camera’s lens! The resulting wider light coverage inside rooms provides additional stray light (reflections) to achieve softer flash illumination.
Example of extended zoom mode:
The focal length set on the camera lens is 35 mm. The extended zoom mode sets a 28 mm reflector position on the mecablitz even though 35 mm conti- nues to be indicated on the LC display!
The extended zoom mode is only possible in the „Auto Zoom“ mode with a focal length setting of 35 mm and longer. Since the start position of the zoom reflector is 28 mm, a focal length of less than 35 mm will cause „28“ to flash on the LC display, thereby warning the user that the required 24 mm reflector position for extended zoom mode cannot be set.
☞Shots with a 28 mm to 35 mm focal length of the lens will be correctly illuminated right out to the image corners by the mecablitz also in extended zoom mode!
Turning on the extended zoom mode
•Continue depressing the „Select“ key combination (= „Mode“ key + „Zoom“ key) until „Ex“ appears on the LC display.
•Continue depressing the „Zoom“ key until „ON“ flashes on the LC display.
•The setting becomes instantly effective. The LC display is switched back to its normal state after approx. 5 sec.
After the setting procedure, the „Ex“ symbol for extended zoom mode will continue to be indicated on the mecablitz LC display!
☞Please note that the wider illumination coverage in extended zoom mode results in a diminished maximum flash range!
Turning off the extended zoom mode
•Continue depressing the „Select“ key combination (= „Mode“ key + „Zoom“ key) until „Ex“ appears on the LC display.
•Continue depressing the „Zoom“ key until „OFF“ flashes on the LC display.
•The setting becomes instantly effective. The LC display is switched back to its normal state after approx. 5 sec.
After storage in the memory, the „Ex“ symbol for extended zoom mode will no longer be indicated on the mecablitz LC display.
5.7 AF measuring beam
The AF measuring beam is activated by the camera electronics when the |
|
ambient lighting conditions are insufficient for automatic focusing. The AF |
|
beam projects a striped pattern on to the subject, and the camera uses this |
|
pattern to focus automatically. The AF beam has a range of approx. 6 m to |
|
9 m (with a 50 mm/f/1.7 standard lens). Parallax error between lens and |
|
AF red light emitter limits the |
|
| |
approx. 0.7 m - 1 m. |
|
☞ The camera lens must be switched to AF so that the AF measuring | |
beam can be activated by the camera. The AF mode „Single AF“ or |
|
| |
rating instructions). Zoom lenses with a lower initial aperture can |
|
| |
significantly reduce the range of the AF measuring beam! |
|
The striped pattern of the AF measuring beam only supports the camera’s central AF sensor. We therefore recommend to activate only the central AF metering area on cameras that feature several AF sensors (please refer to the operating instructions of the given camera).
If a decentral AF sensor is manually selected by the photographer, or auto- matically by the camera, then the emitter of the AF measuring beam on the mecablitz will not be activated. In such instances some cameras will use their
