169The values indicated will be one half of the FZ200 lens setting. It willselect the largest zoom setting which is smaller than or equal to the lensfocal length used.Zooming can be also done manually; the zooming is done internally withno physical change in size of the unit.If you have a wide angle conversion lens then you can flip over a wideangle diffuser. This gives you 8mm flash light coverage.Tilt and swivelThe head can be tilted a little bit downwards, suitable for close-up focusdistances. Tilting downwards gives a warning symbol on the display. Itcan also be tilted 45°, 60°, 75° and 90° upwards.The head can also be swivelled 30°, 60°, 90°, 120°, 150° and 180° to theleft, and 30°, 60° and 90° to the right. The tilt and swivel can becombined.Tilting upwards or swivelling automatically zooms to 25mm, regardless ofthe zoom setting on the lens. However, the zoom can still be operatedmanually.TTL exposure modeAll modern system cameras are expected to offer TTL flash control thesedays. In film based camera a small sensor “read” the light reflected fromthe film and terminated the flash when there had been sufficientexposure. In the FZ200 this exposure determination is done in a differentway.Before the actual exposure, a small pre-flash is done. The pre-flashexposure is read by the image sensor, and used to decide how muchflash to apply in the actual exposure.There is a clear advantage with this solution: The camera can examinethe pre-flash exposure thoroughly before deciding upon the mainexposure.In face detection mode, for example, it can take extra care that the facesare correctly exposed.
