Canon Speedlite 580EX review
Canon’s top-of-the-line Speedlite has been thoroughly revised.
It’s smaller and lighter than ever, yet provides a bit more power and
significantly faster recycling. A new Select Dial makes changes, like
exposure compensation, a breeze. It now covers lenses as wide as 14mm, and
has new features for digital SLRs - including the ability to transmit
precise flash colour temperature information, and vary the zoom setting to
match the imaging sensor.
Approx. 25% faster recycling time compared to 550EX.
Superior evenness of exposure, centre to corner of frame.
Slightly higher max. guide number at 105mm setting (GN 190, feet).
Auto conversion of flash coverage with compatible digital SLRs.
White Balance info communicated instantly to compatible digital SLRs.
Full swivel, 180° in either direction (first TTL flash with this ability).
AF-assist beam now compatible with all AF points on every EOS SLR.
New Select Dial for easy inputs and user control.
