Canon 580EX II Speedlite Flash Unit

Product Information

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. Users of older and non-sealed bodies will not get this final sealing protection, though the rest of the flash is sealed. 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. When set to "On" the Sender will contribute to the overall exposure. When set to "Off" the Sender will control the receivers without contributing to the overall exposure.

Of course, a little flash exposure compensation results in identical results in most circumstances. Fast and silent recycling; keep shooting and the 580EX II keeps blasting out the power with no waiting.

Newer Canon DSLR bodies have the ability to control the flash from their menus - this becomes the easier method of controlling this flash option. The Canon Speedlite 580EX II Flash can control (master) and be controlled by (slave) compatible Canon Speedlites as well as the If your subject distance is consistent (formal portraits for example), a manual flash output setting can eliminate shot-to-shot exposure variations. Using my original 580EX flashes and a new 580EX II, I tested various scenario, camera, lens and setting combinations (including the expireDaysIfNo: typeof mcxPresetParam.expireDaysIfNo === 'number' ? mcxPresetParam.expireDaysIfNo : 30, //days

Use High Speed synch when you need a shutter speed higher than your camera's max flash synch speed (typically 1/200 or 1/250) - such as outdoors with a decent amount of light. The catchlight panel is only useful to a certain distance as the reflection size becomes too small to be useful at some point. The answer may be obvious to owners of camera bodies without a built-in flash, but not so clear to those using bodies with a built-in flash. To use fill flash, set your exposure for the ambient light, then dial in -1 to -2 EV FEC (Flash Exposure Compensation). The 580EX II is powerful, fast, flexible and quiet, and today sells used for next to nothing. If you're not using radio control and are using it on-camera or with optical remote wireless control, there isn't anything better. The 600EX series does recycle a little faster, but the power is the same (bolstered only by a slightly better reflector system at the longest zoom settings) and this 580EX II recycles super-fast. This 580EX II recycles in just 4.1 seconds from a full-power dump, and does it silently. It usually recycles instantly.And the first thing we need to deal with regarding this new flash is the name - The original flash was touting its ETTL-"II" capabilities in its name and now we have the 580EX "II" - which is still E-TTL II. 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 Canon calls this the "EM" mode as it comes up on the LCD as you press the MODE button. This stands for External Manual Flash Metering, meaning that the exposure is controlled automatically by a sensor on the front of the flash (not in the camera). You have to set your ISO and aperture on the flash manually so it can calculate the exposure. The 600EX-RT is mostly the same with slightly faster recycling and adds radio control to optical control. It's the same size, weight and has the same power, although it does have an improved reflector system that can zoom longer so the specifications make it seem more powerful. Use second curtain flash synch when taking an exposure with subject motion blur - the motion will flow to the end of the exposure which will be accented by the flash.

The final sealing at the camera's hot shoe requires the changes implemented in the announced-at-the-same-time and appealing-to-the-same-photographers The Sender will control all receivers set to the same channel. Receivers set to a different channel will not fire. expireDaysIfYes: typeof mcxPresetParam.expireDaysIfYes === 'number' ? mcxPresetParam.expireDaysIfYes : 30, //days

All wireless functions are off. Only basic functions such FEC, FEB and High-Speed/Second-Curtain Sync are available. I use my 580EXII when I'm using longer lenses and/or shooting in daylight at longer distances. For most conditions the 320EX is more than enough. Using one button, the 580EX II head rotates 180 degrees to both sides as well as 90 degrees upward and 7 degrees downward.
