Canon also sells several supporting accessories for its Speedlite products.
 The 600 EX-RT features new bi-directional 2.4 GHz wireless radio communication, compatible with the also-announced Speedlite ST-E3-RT transmitter; as well as backwards compatibility with the optical triggering of any combination of Speedlite 580EX II, 580EX, 550EX, 430EX II, 430EX, 420EX, 320EX, or 270EX II flashes. So I sold my 320EX on eBay and used the money toward another 430EX II. Canon's wireless flash system makes it easy.
At introduction, the 90 EX was bundled with all EOS M kits sold in the EU, though not in the U.S.. Take photos and experiment with the configuration.
Evaluative-Through The Lens (E-TTL) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure.
The 430EX II is meant to succeed the 430 EX and was announced on June 10, 2008, while the Speedlite 430EX was first announced on 22 August 2005. It does not feature an LCD screen like 400 series systems but has several LEDs indicating zoom position and other functions.  Until the release of the Speedlite 580EX in late 2004, the 550EX was Canon's top-of-the-line flash.
I love the 430, and I have lots of them. Each system represents different approaches to achieving the proper flash exposure.
This flash is a unique on-camera light featuring Auto Intelligent Bounce technology.
The flashes in the 500 EX series can act as a controller that enables wireless control of other flashes. 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.
Can be mounted on the front of a macro lens, This page was last edited on 13 July 2020, at 04:18. This triggering technology may eventually replace the old light-based triggering system (which is also built into the 600), because the older system is less reliable, limited by distance, and requires a line-of-sight between the master and slave.
One of the best flash for Canon EOS RP.
3. with the less expensive Canon flashes like the 430EX II. Choose easy wireless flash. Make a note of the channel that the camera is using: this should be channel 1 by default.

Flashes being triggered by the ST-E2 can be assigned to either group A or group B, and the ST-E2 can be configured to with a user-set ratio of flash output between the two groups, with ratios varying from 8:1 to 1:8 in half-stop increments. The Speedlite ST-E3-RT was also announced on March 2, 2012.
It has no infrared focus-assist beam to help you focus in the dark (instead it does that annoying strobe thing), and while it can tilt to bounce from a ceiling, it cannot swivel from side to side.
Like TTL (and like the actual flash metering, but not the pre-flash, of A-TTL), the sensor is internal to the camera and takes its exposure via the lens so any filters added to the lens will also affect the E-TTL readings giving more accurate exposure information to the camera. The main light-metering technologies are known as A-TTL, E-TTL, and E-TTL II.
This will bring up the channel and slave options. This Speedlite can also be used with other compact digital camera models equipped with a dedicated flash shoe mount. You have one of the small G-series Canon cameras that has a flash hot-shoe, but which would be overwhelmed by the size of a full Speedlite. Canon currently produces three flash products for macro photography.
The line was first introduced in 1987. One reviewer noted that the flash occupied a completely new niche in the Canon flash lineup, "slotting between the 270 EX II and the 430 EX II", and added that it did not replace a previous model. The ST-E2 also uses a modulated flash tube for this purpose, but it is fitted with a near infra-red filter (it serves no other purpose).
It has gone through a number of revisions over the years, as new flash exposure metering systems have been introduced.
Evaluative-Through The Lens (E-TTL) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure. Many of us have been manually attaching third-party radio triggers to our flashes to get this RT functionality, and now Canon has built it in. This is usually found in the first page of the shooting menu (red camera icon). Press the Q button on the back of the camera to flick through the selections on the screen and scroll until you find the flash icon.
Select this by pressing the Set button. The amount of light returned from this preflash is used to determine an appropriate tradeoff between aperture and shutter speed in P mode. Customers are advised to "not use this product in areas it was not designed for". I consider the 430EX II to be the core of the Canon flash family.
I find that when I’m shooting video, I need stronger lights, and when I’m shooting stills, I need a more capable flash. You should see the front receiver start flashing, which means it's ready to receive a signal.
We delete comments that violate our policy, which we encourage you to read. And if you have one of the newer cameras, like the 7D, 600D, and others, where the built-in flash can act as a master, you may never need a 580EX II at all.

Nikon users can click here for a separate tutorial covering the same steps. Depending on the specific flash unit and whether or not it is set to bounce, the preflash might be infrared or it might be the normal white flash. If you can't find the icon on the screen using the Q button method, simply press the menu button and scroll until you see the Flash Control option. Get a price on the Canon Speedlite 600EX-rT at Amazon. All three products so far have included a controller that enables wireless control of other flashes. You can watch a video version of this review at: http://steeletraining.com/tutorials/speedlite. It was mediocre both as a still flash as as a video light. Canon's external flashes with model numbers in the 500 and 600 ranges tend to be their high end external flashes. This unit is very similar to 430EX in terms of E-TTL functions and power levels.
The EOS flash system is capable of wireless multiple flash control, whereby a master flash unit IR (ST-E2) or RF (ST-E3-RT) transmitter mounted on the camera body can control up to 3 (optical) or 5 (radio) groups of flash units.  The flashes can be used as a wireless slave unit with Canon Speedlite Transmitter ST-E2 or top-of-line flashes with built-in infrared controller, such as Speedlite 550EX, Speedlite 580 EX or Speedlite 580EX II. The Speedlite 420EX is an external flash formerly made by Canon. Both the 600EX-RT and ST-E3-RT may be subject to legal restrictions of use when in their Radio Transmission (RT) mode.
Canon's EOS flash system refers to the photographic flash mechanism used on Canon's film (35mm and APS) or digital EOS single-lens reflex cameras. It has a quoted range of 10-15m indoors, and 8-10m outdoors.
Speedlite is the trade name for Canon's line of external flashes for use with their EOS line of cameras.
And although the 430EX II is somewhat less powerful than the larger flashes, I find its smaller size and lighter weight more comfortable for long hours of on-camera flash photography.
It can swivel and bounce.
The Speedlite 580EX and Speedlite 580EX II are flashes made by Canon for use with their EOS line of cameras. Either or both patterns would be projected depending on the body being used and the user's selection of autofocus sensor(s).

Get a price on the Canon Speedlite 270EX II at Amazon. A built-in focus assist light allows the ST-E2 to be used to help a camera focus in very low light. Models include 270 EX II, 320 EX, 430 EX I and II, 580 EX I and II, 600 EX, A second speedlite (not essential if you only want to use one light).
Canon’s latest best selling speedlite flash. 'Hotspots' (areas of high reflectance) that would normally throw off the flash metering system are also ignored in the calculation.
So let’s take a quick run through the current Speedlite lineup, from low end to high end, to see if we can determine which flash is right for your needs. Canon dSLR with wireless flash control built-in.
Introduced in 2000, Speedlite 220 EX is a compact entry-level flash unit with a guide number of 22 m (at ISO 100). The 320EX is a new flash designed to serve two purposes simultaneously. E-TTL II is implemented in the body, not the flash unit, and therefore can use existing E-TTL flash units and EF lenses. There are many more ways to add to the configuration, including setting up groups and using firing ratios for more precise exposure control.
The Canon EOS 7D is the first Canon body to be able to control Speedlites wirelessly without the use of a Master Speedlite or IR transmitter; four other EOS models, the 60D, 600D, 650D, 70D, and 700D, also have wireless flash capabilities. Given these limitations, I see only three situations where the 270EX II makes sense: 1.
