Using the Built-in Flash
●When using an EX-series Speedlite (→92), 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 EF16-35mm f/2.8L USM, EF28-70mm f/2.8L USM.
Super-telephoto lenses, including the EF300mm f/2.8L IS USM and EF600mm f/4L 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.
● 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 AF point and weighted for the main subject.
●The built-in flash and external flash cannot be used at the same time.
●If the camera finds it difficult to focus, the AF-assist lamp (→39) will light automatically (except in the <
> and <
> modes).
● You can disable the AF-assist beam and built-in flash. (C.Fn-5→122)
●You can set the Shutter curtain sync to 2nd-curtain sync. (C.Fn-8-1→124)
●In the aperture-priority AE mode with flash, you can set the sync speed to 1/200 sec fixed. (C.Fn-6-1→124)
