For whom is this flash is useful? For those who do not operate their camera in the green Auto mode. The flash must be set exactly the set aperture and shutter speed of the camera to match the flash output, then incur the images that had been with the trigger in the head.
They have no idea of the images before they pull the trigger? Then you will probably use their camera also mainly in the green full auto mode or scene modes (portrait, sports). In order for this flash is not appropriate for them because of the flash to use sensible, you have to worry about to their use, how the image should look like the ratio of ambient light and flash light should be. Who does not like, should look for TTL flashes that do everything automatically, but do not look like the picture to us will therefore always produce the same, unprofessional image look.
Who further reading here, is probably more to the group of distinguished photographers, not to the group of photo-clippers. To those must be said:
-The Processing is good,
-The Operation is fixed and the advanced menu navigation is very easy thanks to enough buttons and display,
-the flash is at full power really bright. This is sufficient for interiors, but flash against the sun is not always
possible.
-The built-in radio receiver saves space and money, if you want to flash unleashed
-Thanks to the power cell of the flash can be triggered by the camera flash.
-There's even a radio transmitter, which can not only cause but also control the power and the electrical zoom function of the camera. This comes in handy when the flash is set high on a tripod or far away from the camera.
# With discharged (cheap) batteries increases the time between flashes at full power on 20 seconds
