when used with the Tr-,A Auto Flash system for flash
photography, the camera's direct rrl metering system takes
over to automatically control the flash output refelected off the
film surface. With its shutter control dial set at "A" (AUTO), the
camera automatically switches to the flash synch speed of 1/60
sec. upon recycling of flash unit, and couples to any aperture of
the lens in use. Because of the direct TTL flash meiering system,
you will find it easy to employ such advanced techniques
as
bounce flash, diffuse flash and close-up flash. Also, the camera,s
exposure compensation system can be coupled to adjust the
flash output, and the necessary exposure information is displayed
in the viewfinder.
The Tl-A Auto Flash system consists of the clip-on types Tl-,A20
and rt-A30 and the grip-type RTF540. Various cabtes'for
extension and multiple unit purposes are available.
'
lf you want a direct TTL frash metering capabirity for your
RTF540, use a Tl-A adaptor which is avairible as an optional
accessory
