There are two new automatic flashes from Canon directed toward new users of the new Canon Rebel T3i and the Canon Rebel T3. These two new flashes are the 270 EX II and the 320 EX. Beginning with the 270 EXII, it is an upgrade of the former 270 EX, and it is designed to work remotely as either a slave or to trigger the camera remotely.
Both flashes carry the trusted “Canon Speedlite” name.
Both of these features make this flash quite unique for those who are just starting out with digital SLR photography. When you use a flash as a slave unit, you can have the flash somewhere away from the camera and it can highlight parts of your photograph that were not possible with the flash attached to the camera. In addition, you can set up your Canon 270/unit to remotely fire the camera and also place the flash in a position to enhance your photo.
There are three other things that make the to 270 EXII attractive to new buyers. The first one is that the cost of this little flash is the least of any Canon flash on the market. The market price at this moment is only about $150. The second thing that makes it attractive to new buyers is the size of the flash unit. It can easily fit in a pocket or small carrying case, it runs on two AA batteries, so it is easy to replace the power supply. And finally, the 270 ESII is attractive to new digital SLR owners simply because it is so easy to use. When someone is trying to and to learn a new camera, it makes sense that the accessories don’t overwhelm the new photographer.
Above the 270 EXII in the Canon heirerarchy is the Canon 320 EX. As the name might suggest this flash is a little bit more powerful. But it also has a feature that has never been offered on a flash that was meant for a Canon digital SLR. The 320 EX includes an LED light for use with video. You can use the Canon 320 EX in the same way as the to 270 EXII, in that you can set it up remotely as a slave, or it can be the remote trigger for your Canon Rebel T3i camera. This flash has some extra buttons and features on the backside to give you a little bit more control, and it runs on four AA batteries.
Both of these flash units have been highly regarded because of their ability to remotely control the Canon rebel.
Canon has a new external flash to accompany the new Canon Rebel T3i/600D. Keeping in line with the creative software additions to the T3i, the new Speedlite has some added functionality that has not been available on previous Canon Rebel Cameras.
A couple of things to note here:
Part of the technology of the Canon Speedlite 320ex includes a new LED light that can be used when the T3i is in video mode. This is a first for Canon DSLR camera flashes.
The Speedlite 320EX can be used to fire your Canon Rebel T3i remotely (from the flash unit), and it even has a delay so you can make sure your flash is correctly positioned.
Wireless Flash For Your T3i/600D With The Canon Speedlite 320ex
Setting up your Canon Speedlite 320ex is very "easy".
The Rebel T3i’s Easy Wireless mode makes controlling compatible Speedlites using the pop-up flash quite simple. Once the Speedlite is set to slave mode and the same channel as your Rebel, you can adjust the flashgun output using the in-camera flash exposure compensation feature.
Custom wireless mode provides even more control over the flash. It is possible to set the pop-up flash to not fire when the slave fires. You can even changes the lighting ratio between the two flash units (the pop-up and the Speedlite). This kind of control has not been available on any previous entry-level models.
From Canon about the Canon Speedlite 320ex
In a first for Canon Speedlites, the versatile new Speedlite 320EX features an LED light on the front of the flash body that can be used to illuminate nearby subjects in dim light. The light is ideal for video recording but can also be used as a modeling light or as an AF assist beam during Live View shooting. When used with EOS DSLRs that have integrated Speedlite transmitters, the Speedlite 320EX can be used as a wireless slave unit positioned off-camera. A flash release function further facilitates wireless flash shooting by enabling the shutter to be released remotely from the Speedlite 320EX with a two-second delay, which gives the photographer time to re-aim the flash if necessary. The Speedlite 320EX combines rich bounce functionality with high performance, ensuring smooth, professional-looking results.
