Auto Internal Zoom Mechanism
The Speedlite 300EZ has an auto zoom
mechanism which automatically adjusts
flash coverage angle to use flash energy
more effectively.
When the shutter button is pressed halfway,
the flash head position automatically ad¬
justs according to the lens focal length.
When using a zoom lens, it also switches
automatically according to zooming. The
position setting of 28, 35, 50 or 70mm will il¬
luminates in the zoom mechanism position
indicator on the back of the flash.
• The guide number varies according to the
flash head position, see p.23.
AF Auxiliary Light
In dark settings difficult for autofocusing,
the AF auxiliary light automatically emits to
help the
camera focus.
The
effective
distance range is approximately 0.9-6m
(3-19.7 ft.) If the subject is too far away, the
AF in-focus indicator blinks. Remove your
finger from the shutter button and move
closer to the subject until the AF in-focus in¬
dicator stops blinking when repressed.
