•
When using an EX-series Speedlite, 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. Other-
wise the lens barrel may partially obstruct the flash coverage and cause part of the
image to look dark.
•
When using the built-in flash, detach any hood attahed to the lens. A lens hood will
partially obstruct the flash coverage.
•
When a super telephoto lens or fast, large-aperture lens is attached, the built-in flash
coverage might be obstructed.
•
The built-in flash’s coverage is effective with lens focal lengths as short as 18mm.
Lens focal lengths shorter than 18mm will result in flash shot having a dark periphery.

“

charged.
•
E-TTL is an abbreviation for Evaluative-Through-The-Lens.
•
In <
> or <
> mode, if you set the shutter speed faster than 1/200 sec., the
camera will automatically reset it to 1/200 sec.
•
AF flash exposure is always based on the aperture value at the time the shot is taken,
and controlled by E-TTL autoflash linked to the active AF point and weighted for the
main subject.
•
If the camera finds it difficult to focus, the AF-assist lamp (

cally (except <
