Product Description

Amazon.com Product Description

The Canon Speedlite Transmitter ST-E2 is compatible with Type A EOS cameras (E-TTL, auto flash) and Type B EOS cameras (manual flash). The ST-E2 is designed to control slaved Canon 550 EX flashes, enabling simultaneous flash use in professional settings. The wireless controller has a flash ratio control, allowing for several different A:B ratios, 1:8 to 8:1 in half-step increments, as well as slave confirmation via a test transmission button, which sets off slave A, followed by slave B, at 1/64 output.

Straight on lighting from a camera mounted flash is unnatural and unflattering. The Canon STE2 Speedlite Transmitter is a must have item if you own a compatible Canon Speedlite (580EX/550EX/420EX/430EX). Your subject will really appreciate not having the flash pointing directly into their eyes. Plus, with the right angle, you can cast natural looking shadows that will greatly improve the look of your portrait shots. With this transmitter you can place your Speedlite anywhere you like to get the perfect lighting for the shot. It's a really great system when used with two or more Canon Speedlites. I own two Canon 430EX Speedlites that I use with this transmitter. One flash I use as the main light source is fitted with a unidirectional diffuser to soften the light. The other flash used as a fill flash is fitted with an omni-directional bounce diffuser. This transmitter allows you to easily set the balance of light between two Speedlite groups (group A and group B). You simply press a button on the back to adjust the balance. A lighted meter on the back of the transmitter shows you the balance setting. This allows you to easily balance the light between both flash groups without having to touch or move any of the flash units. Very handy! With this setup, you can create professional portrait shots with ease, and not have to worry about lugging around a bunch of heavy lighting equipment. I HIGHLY RECOMMEND THIS PRODUCT!

I used the STE2 with two Canon 430EX Speedlites to do some portraits with excellent results. I mounted the Speedlites on stands with 30 inch shoot-through umbrellas using hot shoe multiclamps. I shot with a Canon 50mm f1/4 lens on a Canon 30D set to manual with a 1/60 shutter and f4 aperture. With E-TTL enabled, the flash power is automatically adjusted to obtain the correct exposure. I found the flash power to generally be right on but on the occasion I felt it wasn't, I simply adjusted the flash compensation on my camera. I did not need to meter or use a gray card so I was able to focus more on composition.

I really like the convenience of this wireless setup because there are no cables to trip over and that makes it really easy to move my lights around and try different angles. With a two flash setup, you can easily change the ratio between the two flash units on the back of the transmitter without touching anything else. This often helped me get better shots because I could quickly modify the light setup to capture a moment without stepping out from behind the camera.

I would prefer radio control but this setup is very compact and I did not have any problems with the Speedlites not firing even if they were not quite in direct line of sight. I even turned my shoot-through umbrellas around to act as reflectors, effectively blocking the line of site between the camera and the Speedlites, and they still fired so apparently there is a bit of flexibility in that line of site.

Update 5/25/2007: Although the STE2 worked well for portraits in relatively small rooms, I recently tried to use it for some wedding formals in large churches, reception halls, and outdoors and found it didn't work so well. Even after putting in brand new batteries, I was quite limited on where I could position my flashes so they would still fire. I had to have the flashes in front of me and just off to the sides for it to work. I have since decided to purchase some radio slaves for my wedding work. The other thing I noticed is that if you are shooting a bride in a white dress, E-TTL will tend to underexpose the shot so its value is diminished which makes non-TTL flashes and old-school metering for off camera formal work much more desirable.

First off while the name given by Amazon only lists the 580EX, 550EX and 420EX speedlites, the STE2 transmitter will also work with the 430EX.

I got this transmitter after being inspired by the potential an off camera flash can have after reading Strobist. I got two 430EX flashes to get a very portable and easy to set up lighting system.

The STE2 Transmitter allows you to control an unlimited number of flashes in a few different ways. As long as the visual signal can reach the flashes, they will fire (indoors this is easy because the signal bounces off walls).
The STE2 lets you control the relative flash output between two flashes (or groups of flashes) through a simple control on the back. For example you if you set it to 1:8 between A and B, B will get 8 times the 'power' as A.

Even without two flashes, the STE2 lets you move the flash away from where the lens is and creates more pleasant lighting. Additionally, if you take photos of people with glasses or of objects within glass, you can angle the flash so that glare is eliminated.

All in all a great investment, I doubt I will mount a flash directly to the camera ever again.
