Canon 9337B001, 30D28135, 30D1785 manual Using the Built-in Flash

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 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.

● 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.

You can set the Shutter curtain sync to 2nd-curtain sync. (C.Fn-8-1→126)
