Canon Speedlites

Speedlite is the trade name for Canon's line of external flashes for use with their EOS line of cameras. It is similar but not to be confused with Nikon Corporation's "Speedlight" brand for their flashes. The Speedlite name is also used by Ricoh for its unrelated product line of flash units, such as the Ricoh Speedlite 202.


E-TTL II is a software improvement on E-TTL and is now a standard in all EOS cameras introduced with or after the Canon EOS-1D Mark II in 2004. E-TTL II is implemented in the body, not the flash unit, and therefore can use existing E-TTL flash units and EF lenses.

The main improvement of E-TTL II is that it gives a more natural flash exposure, by being able to handle tricky scenes where the old E-TTL system would normally be thrown off. Such improvements are possible because E-TTL II incorporates lens-to-subject distance information in its calculation, where available, to assist in determining an approximate guide number for flash output. The flash metering system is also no longer linked to the AF system, whereas in the old E-TTL metering, bias is given to the selected AF point. Rather, E-TTL II compares the ambient and the pre-flash light levels of the scene to determine where the subject lies, in conjunction with subject distance information if available. This gives the photographer the flexibility to lock focus and recompose the scene without fooling the flash metering system. 'Hotspots' (areas of high reflectance) that would normally throw off the flash metering system are also ignored in the calculation. The brand names are intended to indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or the continuous lighting used in some studio situations.

When shooting with a flash, more creative results can be achieved with Canon's full range of Speedlite flash units. Canon Speedlites are compatible with EOS System cameras for a wide variety of applications for beginners or professional photographers. They range from beginner level flashes that are simple, economical flashes at a low price, up to high-power, highly advanced flashes for professional use. Features such as wireless technology and flash exposure lock make it easy to capture a quality image. For sophisticated wireless flash setups, the Speedlite 600EX-RT and Speedlite Transmitter ST-E3-RT represent the next generation in off camera wireless flash systems. In addition to traditional optical wireless transmission, both facilitate radio controlled, two-way wireless transmission up to 100 feet among five groups or 15 individual Speedlite flashes. Superb lighting is simple thanks to the E-TTL/E-TTL II autoflash system which controls the total flash output to ensure consistently correct exposure. The EOS 7D, EOS 70D, EOS 60D, EOS Rebel T5i, EOS Rebel T3i cameras and additional models, with their Integrated Speedlite Transmitters, can control and trigger external Speedlites wirelessly through their built-in pop up flash. The Flash Exposure Lock (FE Lock), Auto Exposure lock and Spot metering functions provide enough time to not only recompose the shot, but also alter the ambient light exposure for maximum creative control when used with E-TTL compatible EOS DSLR cameras.
