Canon 580EX II Speedlite Flash Unit

Product Information

The Senderr will control all receivers set to the same channel. Receivers set to a different channel will not be affected. You can still utilize the 430EX's focus assist, but need to know that all focus points are not covered as in the 580EX II. Small changes include a repositioned wireless slave sensor and a reconfigured AF assist beam emitter -

You need this table to decode them. Hold the C.Fn button a few seconds, turn the dial to select which function to set, tap the SEL/SET button so the setting blinks and then change it with the dial. Tap SEL/SET again to save it (it stops blinking), and tap MODE to exit the settings. External flashes such as the Canon Speedlite 580EX II Flash are one of the most popular accessories among Digital SLR (and film SLR for that matter) owners. The 580EX II is Canon's top-of-the-line, professional grade external flash - There are very few features missing in this one.Dust and water resistance is a feature that is going to be in heavy demand from sports and photojournalism photographers. Canon stopped recommending lithium throw-aways when they realized they got too hot with heavy pro use. Lithium are great if you're traveling super light and want to bring a few sets of these cells on a long trip where you won't be able to charge them, or if you want to be able to leave a set in the flash and have them still fresh and ready to go ten years from now, but for all other uses, use eneloop. The new one is a little nicer (and likely easier to seal), but the physical change is not significant from a user perspective. All wireless functions are off. Only basic functions such FEC, FEBand High-Speed/Second-Curtain Sync are available.

While both flashes feature a pull-out/flip down wide angle diffuser to cover lenses out to 14mm (FOVCF equivalent), the 580EX II includes a white plastic pull-out catchlight reflector panel in addition. Overall the 430EX III RT is also a marvelous flash, just that it costs twice as much new as the 580EX II used.

The 580EX II sports a more-rugged build quality with a metal foot being one of the most noticeable changes. In addition, a huge range of flash modifiers can be used with accessory flashes to create a broader lighting surface for direct flash, bounce flash or a combination of both.

The 430EX II is just about as good once you get it set up, just with sloppier controls and no catchlight card. If you can use a business card and rubber band as pros have been doing for decades as a catchlight card, the 430EX II is a great flash, just harder to set since it has two plus/minus buttons instead of a rear dial.The transmission range for wireless communication are (periphery-center) 39.4'-49.2' (12m-15m) indoors and 26.2'-32.8' (8m-10m) outdoors. I use direct-flash-as-main-light (typically in "M" mode) only as a last resort, much preferring to use a higher ISO, wider aperture, slower shutter speed, image stabilization, tripod ... document.cookie = encodeURIComponent(sKey) + "=" + encodeURIComponent(sValue) + sExpires + "; path=/"; NiMH batteries also give more consistent (full) power until they are discharged while alkalines will recycle the flash more and more slowly as they expend their life. Use eneloop rechargeable batteries. They don't run down when you don't use them, and are loaded with power for fast recycling even if you haven't used your flash in months.

I definitely like the new, very-professional quiet charging, but I need to relearn my flash-ready indicators. Press the Zoom/Wireless Select Button to access the options listed above. When the option you have chosen is blinking, turn the Select Dial to cycle through the options in parentheses. As each option become available it will blink. Press the Select/Set Button to set your choice. Once set, the option will no longer blink. Note: the adhesive Velcro shown on the original 580EX (above left) is an accessory used to hold certain flash modifiers in place.This operating mode allows you to set the 580EX II to fire repeatedly, during a single long exposure. You can set the firing frequency (flashes per second, expressed as Hz, from 1-199 per second), the total number of flashes during the exposure, and the
