The guide number is 28 as per the model designation. It bounces, zooms and swivels. The flash comes complete with a bracket. This unit is compatible with all CANON cameras with either built-in flash capability or not. It has a hot shoe so that it can be fired from the camera too. It is fully synchronized with fill-in flash and red-eye reduction flash and can be used with virtually all of the digital cameras on the market. It works as a slave. It can be set for a single flash camera or a pre-flash camera, or, it can detect which setting is best.

SLAVE FLASH BENEFITS
Most point & shoot style digital cameras lack hot shoes and any means to fire a second flash unit. But a bracket-type flash that has a built-in slave sensor can be used to fire in sync with the camera's flash. Since digital cameras usually fire a series to flash bursts (to set focus, white balance, etc.) prior to the main burst of light, this slave flash should have a "smart" sensor. This type of sensor will ignore the pre-flashes and fire in sync with the primary burst of light.
A fully dedicated flash will interface with the camera's auto focus and auto-exposure system, while producing considerably more light for greater range and with more creative control than the built-in flash.
A studio flash system with multiple flashes on light stands can be used with digital cameras.
The primary issues are synchronizing the camera with the flashes and controlling exposure. Ideally, the camera will have a PC flash cord terminal or a hot shoe with a cord adapter to fire the flash system.
Otherwise the built-in flash can be used to trigger the slave-equipped studio flash.
The camera will need to have a flash mode that doesn't use pre-flashes, or a "smart" slave that ignores pre-flashes will need to be used. The camera will need to have manual exposure control so the exposure and light output from the studio flash can be balanced.
Ordinary flash units will not work because your digital camera lacks a way to connect and/or mount an external flash. Even more importantly, most digital cameras emit a “pre- flash” and/or a ‘red-eye” pulse that fire before the shutter opens, then an additional flash pulse is fired to actually light your picture. This “pre-flash” (“double-flash”) and/or “red-eye” pulse confuses other flash and slave units , causing them to go off at the wrong time, and are useless for your digital camera.
The Slave Flash has special digital pulse counting slave circuitry that is not fooled by the “pre-flash” and eliminates the need for an electrical connection to your camera. A three-position switch sets the flash to ignore one or two “pre-flashes”, or none at all.
The built in built in flash units of digital cameras are on average effective to only about 12 feet, and that's when your lens is at its widest-angle setting. When you want to zoom in on the action (towards the telephoto end of your zoom range) you'll find that your built in flash does exactly opposite of what you want, its range is reduced to about 8 feet, and sometimes even less! So, when you want to use your camera's telephoto capability that you paid for, but also require the built in flash, your pictures come out dark or, even worse, not at all.
In addition to its digital pulse counting slave circuitry, the Slave Flash comes equipped with a built in hot shoe, quick release mounting bracket and pc sync cord. The Slave Flash is compatible with virtually any digital or film, point- n'- shoot or SLR camera you might own .
The Flash Has A Hot Shoe And Can Be Attached Directly To Your CANON Digital Camera's Accessory Shoe, If One Is Provided. If Your CANON Digital Camera Does Not Have A Built-in Flash, The Flash Will Operate As A Slave Unit Next To Your Digital Camera. In This Case, Either Mount The Flash On The Accessory Shoe Of The Mounting Bracket (Supplied) And Attach Next To Your Digital Still Camera By Tightening The Knob, Or Simply Mount The Flash On The Mini Tripod (Supplied) Place On Any Flat Surface.
