Canon 580EX II Speedlite Flash Unit

Product Information

NiMH batteries have much less internal resistance than alkaline batteries resulting in significantly shorter re-cycle times (up to 50% faster). In this mode the camera magically communicates its aperture and ISO to the flash so the flash's sensor can calculate exactly how much light to use. Most (but not all) of the Canon Speedlite 580EX II Flash's other changes from the 580EX are good ones ... Export: Some of the software is subject to export controls under the U.S. Export Administration Regulations (EAR), and anyone receiving the software cannot export the software without a license or other authorisation of the U.S. Canon will not be liable for any loss of whatsoever nature incurred as a result of this prohibition.

Non-TTL Auto exposure mode with manual setting of ISO and aperture at the flash (see next section). The 580EX II's AF-Assist Beam is aligned with the focus points on all of Canon's EOS bodies - with 1, 3, 5, 7, 9, or 45 AF points. Other body users can still use external metering, but will need to use the External Manual ("EM") mode which requires the camera settings to be manually entered into the flash.I use my 580EX II when I need power, which is when I'm using it for daylight fill-flash at longer distances with longer lenses. Any of the smaller flashes are fine for every other use, and even for daylight fill if you're not too far away. The 580EX II is rated for approximately 100 to 700 shots from new AA-size alkaline batteries which deliver a fast recycling time of approximately 0.1 to 6 seconds. Small changes include a repositioned wireless slave sensor and a reconfigured AF assist beam emitter - inlineID: typeof mcxPresetParam.inlineID === 'string' ? mcxPresetParam.inlineID : "mcxSurveyDialog",

My comparisons showed external metering, even from a 1D Mark III, to be significantly underexposed (typically 1.5 stops or so) unless the subject was very dark. I definitely like the new, very-professional quiet charging, but I need to relearn my flash-ready indicators. When set to "Off" the Sender and receiver(s) will automatically output the same amount of light. When set to "A:B" you can adjust the auto-exposure ratio between the Sender (A) and receivers (B). When set to "A:B C" you can adjust the autoexposure ratio between the Sender (A) and receivers (B) while adding a separate, independent group of receivers (C). waitUntilClose: typeof mcxPresetParam.waitUntilClose === 'boolean' ? mcxPresetParam.waitUntilClose : false, Keeping the flash mounted higher above the lens to send the subject's shadow lower - where it is not as unpleasant.

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. a) by Service Centers located outside of the United States and Canada WITHOUT CHARGE.

If your subject distance is consistent (formal portraits for example), a manual flash output setting can eliminate shot-to-shot exposure variations. Flashes can all fire at even power (Ratio Off), or you can set groups A, B and C to fire at different manual flash power levels. Press (don't hold) the Zoom/Wireless Select Button until Ratio blinks, then turn the Select Dial to make your choice. Press the Select/Set Button on the Master unit, then turn Select Dial to set the actual power level for each group. All wireless functions are off. Only basic functions such FEC, FEB and High-Speed/Second-Curtain Sync are available.Using my original 580EX flashes and a new 580EX II, I tested various scenario, camera, lens and setting combinations (including the When your Speedlite is set to this option it will function as the Receiver (secondary) unit that is controlled by a Sender set to the same channel. You will be able to make the following additional selections: When this option is selected the flash will flash stroboscopically, in sync with the shutter as it cross the focal plane. Although this allows the 580EX II to synchronize with shutter speeds higher than 1/200-second it also reduces light output as shutter speeds move progressively past the standard maximum sync speed.

cleanseCookie: typeof mcxPresetParam.cleanseCookie === 'boolean' ? mcxPresetParam.cleanseCookie : false, Since the flash head working area size is nearly identical between the two flashes, original size of the light thrown by them is going to be the same. Press the Zoom Button once. When the coverage angle indicator (upper-right of the display) blinks, turn Select Dial to the angle of your choice. The choices are 24, 28, 35, 50, 70, 80, and 105mm, in 35mm full-frame equivalents. Divide by 1.6 for theWhen set to "On" the Sender will contribute to the overall exposure. When set to "Off" the Sender will control the receiverswithout firing during the overall exposure. Because the light source is very small and is located very close to the imaging axis, using the built-in flash as a main light often results in a harshly-lit picture (often with red-eyed subjects). When your Speedlite is set to this option it will function as the Sender (main) unit that controls any other Receiver (secondary) units that are set to the same Channel. It will also allow you to control the automatic power ratio between Sender and Receivers. Yes (I use this, but don't get confused because the green ready light now means it's less charged than the default red one!).
