pro quality flash, and great build, wireless system is great especially with STE2 wireless transmitter, ETTL system is flawless, has only produced mediocore results once in over 50 night sport scenes. Includeds tripod stand!

big, but hey its a pro flash right! for sports, it eats the batteries, but hey I need quick recharging!
also expensive, but hey this is how I eat my rice.

A pro lense, a must for any serious EOS 3 or 1V owner. I own two and have the ST-E2 which is an ideal setup, maybe looking to add a third. The best Canon flash out there, forget the third party brands please, at least for the flash.

With STE-2 (wireless) with other flash as slave, if it is not place well the 550EX won't triggle!

Works great with EOS camera with ETTL capability.
A must with Canon EOS 3 and 1 V.

Great lighting on first roll of Provia 100 slide film for b-ball and team photo. Could see shadows on Gym's walls that indicate it's high light output.

Book says it AF assists (red light) with Rebel S. Canon US said their 550EX and Rebel S did AF assist, mine didn't and it didn't on a store's Elan 7. I returned it for another one

Awaiting delivery of my replacement 550EX because AutoFocus assist didn't work on first one with Rebel S or with store's Elan 7.

Every bit as good, or better than the nearest competition. Results are superb due to the advanced E-TTL metering system. With so many features, I never have to worry about what I need to use for a particular situation - its all built in, just select and use! Most useful features are the wireless master-slave flash control with multiple flash units, the FP flash and rear curtain sync. You just have to try it to believe it! It's very expensive, but once tried and proven, the initially high expense is quickly forgotten because it is worth every dollar!

i got it free.... in the UK canon are doing a deal with the EOS 1v, 3, and D30, giving one of these babies away as an option!!!

a little heavy..but hey, for £00.00, who can complain??

well the Strobosopic is very good, and if you set it up right, it will flash with every one of those 7fps on the EOS with the PB-E2....very useful

Wireless flash,modeling light

Auto exposure metering linked to tiny AF sensor
is poorly conceived. Good luck trying to get accurate exposures.

I don't understand all the praise I've read for this top-of-the-line, expensive, TTL flash. Many of the features are cool, like the wireless flash that works well in SOME situations, and the modeling light option. However, for me getting reliable exposure is so hit and miss that I often dread using the flash for pro assignments and family pictures. I mostly use color negative films and have the benefits of Photoshop software to TRY to fix all the bad exposures but I often wonder how chrome shooters can live with the autoexposure problems. FEL ( flash exposure lock )can be helpful, but realistically there are so few situations that are so static that you can make use of that feature. What it boils down to is that in most situations before you fire a shot with your camera, you have to select a tiny active AF sensor, place it on your moving subject and hope that area is midtoned and not light or dark. And to add to the difficulty, the 38 non cross sensors are often not reliable for critical autofocus. I use my 3 550 EX's for daily photojournalism work and when the exposure is correct it's dead on. But way too often the exposures are all over the place and frequently way to hot. If anyone has a solution I'm dying to hear it. Canon needs to go back to the drawing board, fast !

Good contruction, a lot of light.

Works poorly with ettl combined with AF from the Eos 1v

The foto's are often too light or too dark. This depends one where the autofocus sensor in aimed at. A dark object makes the foto too light, a light object (like a weddingdress) makes the foto too dark. Really irritating. Buying another flash soon. If anybody can help, great! I like to hear it.

Heavy, but worth it for GN55

Much advanced over the 380EX
Totally customisable flash with my EOS3. Work out its priorites in the various camera modes and you can use it to do anything you want. It will easily produce good balance between ambient and flash lighting in P. It will let you sync the background in Av or Tv, etc etc.
Great for sports fill-in
Good recharge with Ni-MH batteries in it. Will cope with 7fps no probs for a second or so, which is fine.
Handy flash range indicator on display, switchable between ft and m
Full AF assist light enables full area AF in ridiculously dark conditions
Buy a Stofen Omnibounce for close people stuff and you've got the lot.

2) Refined E-TTL autoflash for improved performance.

5) FE lock (a flash version of AE lock), and FEB (Flash Exposure Bracketing).

6) Built-in wireless transmitter, which can control other Speedlite 550EX and Speedlite 420EX set up as slave units.

7) Great results obtained from E-TTL flash metering

8) One full charge can fire several frames in rapid succession (depending on distance)

9) Head swivels almost every angle for maximum flexibility

10) Charge-up time between full flash output is much faster than previous models

11) Fully compatible with older flash metering systems (TTL and A-TTL) used by older EOS cameras. It will detect camera & change the flash exposure mode to suit the camera type

14) Very strong and robust construction.

15) Can be fired off remotely using ST-E2 wireless transmitter

1) Too expensive for some

It is as good as, or better than, the closest rivals. Professional results everytime. All shots correctly exposed. I own 3 550EX, 1 420EX, and 1 ST-E2. Combination works like magic, like a mini studio.

A little high price and heavy.

I try a Sigma 500 super before. But it is fully imcompatible with my EOS-3. So I return it and get a OEM item. Everything is great and very happy. But I found out when you use it on EOS-3, 1V and Elan 7. Set the flash manual power output at FP mode. Camera's shutter speed will stay on maximum cannot adjust. No problem on E-TTL/TTL auto mode. Even Canon they don't know why will be like this.
