I use this flash off-camera, with the TTL radio trigger of the same company and it works phenomenally. The build quality is nice, but it is not that conducive to heavy bracket use. So wedding guys using a bracket, event guys that light to bounce light off THINGS walls and the like will be better off with a Canon brand, but for plopping a light on a stand and fixing the angle for the rest of the day as a fill light while outside of the studio this cannot be beat. I also use this for weddings and events, just not on my bracket that I walk around with. OH and uses a LOT of battery, I mean a lot. The radio trigger does too so make sure your assistant keeps cycling them to the charger as you go thru your itinerary... changing rooms!? Change batteries? TIME FOR DINNER?? change batteries. Switching from inside to outside, DEFINITELY change batteries... thats basically the circle of life with this product, but for the PRICE.... it cannot be beat.Read full review

The Canon Speedlite 600EX-RT has one of the highest Guide Numbers with a range of 197 feet. It has an exclusive coverrage range of 20mm wide to 200mm telephoto of the lens view. It is also a radio transmitter which means it can transmit a radio signal to one or more receiver flaslhes up to 100 feet, and doesn't need a clear view to the receiver like an Optical Wireless does. It will find its receiver whereever it happens to be placed. This was my main reason for purchasing the 600EX-RT.

I've now gone full circle from camera flash to a full studio setup to using four 600EXRT's and a transmitter. Gone are my big heavy studio lights with their transformer. When cameras were much less sophisticated you'd need the flexibility of studio lighting. Now that cameras and the Canon Speedlite's have evolved things are much easier. I worried about loosing the modeling light capability of the studio setup until I found out that the 600 EX-RT has one also. I can check shadows and reposition just like in the past but without all the weight and cables. I still use these with the same umbrellas and lightboxes. Setup is much faster and I can modify the settings of any of the lights from the master, or on camera. Gone is the 90# bag with the heads and transformer. This is the first flash from Canon with wireless ETTL and full flexibility.Read full review

I won't write the specs which you can find elsewhere. Using the 600EX-RT is a total breeze. At last, Canon designed an user friendly flash. Previously, I was a Nikon user with the SB-900 and the design and user interface are on par. I have also used the 400EXII and the difference (in usage terms, capability is obviously inferior) is huge. Using radio communication is the simplest way of synchronization I've ever tried. It can be as simple as to just turn on the flashes, set one as a Master, one as a Slave and the link is immediately stablished (and with a led for easy visual feedback) and it doesn't matter where and how you put the flashes. It just works. Reliable. Simple. Fast. My body is Canon 7D and therefore, I can only use radio with ETTL/M/ALL communication. No Group mode (really a shame) And I must tell that with this body (latest firmware installed), you can't modify parameters on Canon 7D screen because the body doesn't know about this new radio mode. If you need to edit parameters on body (External Function Flash), then you have to use Optical slave mode or standalone mode. If you enable "Wireless" from the body's menu, the radio mode will get disabled and you'll get optical mode instead. However, this is where the friendly UI comes to the rescue. I don't miss configuring the flashes directly on the master flash, except when I'm using the extension cable (to get my flash off camera and be able to position where I really need it to be) As a side note, I don't like the ST-3 controller unit because it lacks AF assist lamp and at low EV, the body struggles to find focus without AF assist lamp. Regarding the Custom Functions, you can edit many of them directly in body (Canon 7D), but you must be aware that there are Custom Functions that won't show up in body, and you can edit those only directly on Flash. Again, the new friendly UI lets you do this easily (no more cryptic codes) even with nice icons for each function. The same happens with the new Personal Functions: you can only edit those directly on Flash. Talking about performance, the recharge time is really fast and the capability to keep shoting even if the flash is not fully charged is awesome. I've been able to shot about 2 or 3 times each second (kids event on little auditorium) and I don't get underexposed photos. For the record, I only use Eneloop XX or Lithium batteries which you should consider to get the best out of the flash. The carrying pouch is really nice, but you can only fit the Flash and the cold shoe mount. I wish a little more space, at least for the gels and why not, space for a diffuser. The carrying pouch for the Nikon SB-900 considers all those accessories in a larger pouch. There are some points that could be better: - Better compatibility with "older" bodies. I really miss the new Group mode (controlling up to 5 flashes, in every mode you wish) and some other features you can't have unless you get a "new" body (2012 and ahead) Also, I've explained that you can't configure radio mode directly on body's menus. - Simple dumb optical cell, so I can use this flash with other systems, like Nikon. I was able to use the SB-900 in this mode (SU-4) and I really miss this for Canon. - More gel filters. With SB-900 I got way more but not as many as you get with Rosco. - More accessories, for example a flash diffuser, which you indeed get with Nikon SB-900 - I really like the carrying pouch, but I wish it has more space for the gels.Read full review
I could go on and on about the features of the 600 EX-RT but it's all been said before. What's important to me? Several features you will not find in any flash from any other major camera manufacturer. 1) Exposure compensation: you can adjust the camera exposure compensation independent of the flash exposure compensation. 2) You can use these as studio lights for main, fill or highlight and group up to 15 flash units into 3 banks all adjusted independently from the LCD on the back or your camera. 3) In radio mode the unit scans the area and tells you what channels are clear of interference from other photographers, microwave ovens, medical equipment, etc... 4) All the slave units communicate back to the master letting you know when everything is cycled. You're not going to find this in the lower cost units. You get what you pay for.Read full review
