● 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
〈 〉
or
〈 〉
mode, if you set the shutter speed faster than 1/200 second, the
camera will automatically reset it to 1/200 unless the EX-series 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.
● 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 EF300mm F2.8L IS USM and EF600mm F4L IS USM.
● The built-in 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.
Using the Built-in Flash
You can set the Shutter curtain sync to 2nd-curtain sync. (C.Fn-8-1→126)
