The built-in flash is great for fill flash to light the shaded areas (such as people's eyes) in a pictures. The new one is a little nicer (and likely easier to seal), but the physical change is not significant from a user perspective. The Canon options in my opinion are the Canon Speedlite 430EX Flash or the 580EX II (or possibly a used 580EX). You now have to set the flash to your camera's or film's ISO (it works from ISO/ASA 25~1,600) and your camera's aperture ( f/1 to f/90) manually, and you have to use the camera's Av or M mode to use a fixed aperture. Set these on the flash by selecting the EM mode by tapping the MODE button, then tap the SEL/SET button once or twice until the ISO or aperture blink, spin the dial to select, then tap SEL/SET again to set. To get to this menu setting requires the zoom button to be held for 2 seconds - I could change the old switch in much less time than it now takes just to pull up the menu setting.

The other primary difference is that the 580EX II can be used as a master to trigger remote Canon wireless slave flashes while the 430EX can only act as a slave flash. These all take the same pictures, and have surprisingly similar maximum power outputs at wide settings. The lens systems of the bigger flashes give them more power at longer focal lengths as they're better able to focus the light. The 580EX II sports a more-rugged build quality with a metal foot being one of the most noticeable changes. Accessory flashes such as Canon Speedlite 580EX II Flash are some of the most important pieces of equipment in my kit.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: (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] 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 ...

Camera and subject motion can be issues in this mode - unless a custom function (provided only on some cameras) is selected to increase the shutter speed. Seeking the best printer for your business?

At certain shutter speeds, the second curtain starts to close before the first curtain is completely open - standard flash mode needs a wide open aperture for the instant it flashes light.var isSafari = /constructor/i.test(window.HTMLElement)

The 430EX has a Guide Number of 141' (43 m) while the 580EX II has a Guide Number of 190' (58 m) (both at 105mm).The 580EX II is Canon's top-of-the-line, professional grade external flash - There are very few features missing in this one. The reshaped flash body immediately reminded me of the 580EX's predecessor, the Canon Speedlite 550EX. var isOpera = (!!window.opr && !!opr.addons) 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 mode
