Canon EOS D30 - Manual (Page 92)

Using the Built-in Flash
When using an EX-series Speedlite (->-96), press the built-in flash back into the
camera before mounting the external flash.
When using the built-in flash, keep at least 1 m/3.3 ft away from the subject.
Otherwise the lens barrel may partially obstruct the flash and cause part of the
photo to look dark.
When using the built-in flash, detach any hood from the lens to keep It from
obstructing flash coverage.
Using the built-in flash with any of the following lenses can partially obstruct the
flash coverage. Instead, use an EOS-dedIcated external flash.
Large-aperture lenses, including the EF17-35mm F2.8L USM, EF28-70mm F2.8L USM.
Super-telephoto lenses. Including the EFSOOmm F2.8L IS USM and EF600mm F4L IS USM.
The bullt-ln flash can cover the picture area for lenses with focal lengths as short
as 18 mm. If you use a lens shorter than 18 mm, the photo will be dark around
the edges.

The ‘E’ in E-TTL stands for ‘Evaluative.’
To retract the built-in flash, press it back down into the camera.
You cannot use the built-in flash to set high-speed sync (FP flash).
In ( T v ) or ( M ) mode. If you set the shutter speed faster than 1/200 second, the
camera will automatically reset it to 1/200 unless the EX-serles Speedlite has
been set for high-speed sync.
AF flash exposure Is always based on the aperture value at the time the shot is
taken, and controlled by E-TTL automatic flash compensation linked to the active
focusing point and weighted for the main subject.
The built-in flash and external flash cannot be used at the same time.
For subjects that are difficult to focus, the AF-assist light (^43) automatically
projects a beam of light at the subject.
C.Fn You can set the Shutter curtain sync to 2nd-curtain sync. (C.Fn-8-1->-126)
