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. Malfunction resulting from the use of accessories, attachments, product supplies, parts or devices (including, without limitation, batteries, film, lenses, flash attachments and other accessories) with this Canon photographic equipment that do not conform to Canon specifications. 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. The built-in flash is great for fill flash to light the shaded areas (such as people's eyes) in a pictures.

During stroboscopic flash, the shutter must remain completely open while the Speedlite is flashing and close as soon as the flashing stops. Use the formula below to calculate the necessary shutter speed. Manual flash output can be controlled in 1/3 stop increments - 1/1, 1/2, 1/4, 1/8th, 1/16th, 1/32nd, 1/64th & 1/128th.

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 var isOpera = (!!window.opr && !!opr.addons) waitUntilClose: typeof mcxPresetParam.waitUntilClose === 'boolean' ? mcxPresetParam.waitUntilClose : false, Those using Canon bodies with 45 focus points (1-Series bodies) should take note that the Canon Speedlite 430EX Flash's AF assist only covers up to 9 focus points. What is not faster to use - what I don't like - is the now-menu-located off/master/slave remote flash setting (notice the switch is missing in the above picture - more about this function later).

Dust and water resistance is a feature that is going to be in heavy demand from sports and photojournalism photographers. This operating mode uses the camera's light meter to automatically control flash output and exposure. It can control a single Speedlite attached to the camera and can also wirelessly control multiple Speedlites. The basic functions available in this modeThis mode measures exposure with a sensor on the front of the flash. It is not measured through the lens (TTL) in-camera when set this way, it's measured "externally" at the flash itself. flash output. Note: Although any wireless flash settings you have made will remain active while you are in Multi Mode, the results can be unpredictable. It's best to test the exposure and effects before combining wireless flash with Multi Mode. Speedlites can be combined as slave units but only the Canon 580EX II, 580EX and 550EX Speedlites can act as slave masters.

The wireless remote capability of Canon's Speedlite flashes (discussed above) offer even far greater advantages.The 580EX II is Canon's top-of-the-line, professional grade external flash - There are very few features missing in this one. 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 zoom setting is optimized for the camera and lens being used - Less light is wasted, battery life is maximized. 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.
