Everything came perfectly new and works great. It has been great to add this flash for certain photo shoots.

The 600EX II-RT works great on its own. However, I have 4. As a wedding photographer, I need my on-camera and remote flashes to reliable function in a different building every weekend. The built-in wireless triggers are unreliable. Depending on the building, the connection between the on-camera flash and the remote flashes will drop every few minutes. The only way to reconnect is turn each remote flash off and on again. This is a completely unacceptable level of reliability for the price and totally unworkable in a professional event setting. I'll be selling mine.

Ordering my speedlight flash was made very simple. The process was straight forward and user friendly. My Canon Speedlite 600EX II-RT works beautifully! It is a bit pricey but you get what you pay for. This is one of the best in the market. I am extremely happy that I decided not to be cheap with my flash.

It works really well in low light - specifically in clubs or dark locations. It?s been one of my most consistent flashes. Tried to godox round flash before this one and it did not light the same.

What can I say... it's a Canon Flash and they're great products. It's weather sealed and sturdy. I do wish they had the Lithium power packs like the Godox/Flashpoint flashes do though.

Flash is awesome has plenty of power and recovery time is excellent. High sync works well.

My best light investment and a good combination with my EOS 5D mark IV. Easy to use and manipulate.

After years and years of procrastination, I finally decided to purchase a Speedlite. I've always been a "use the light that you are given" photographer, which obviously makes certain shoots a chore (other than the occasional use of lightsticks, ring lights, etc...) I knew that there was a world of photography that I had yet to experience, simply because I was too stubborn to purchase a decent flash. Seeing as I have the camera (R5) and lens, I figured that it was finally time to bite the proverbial bullet. And now I'm kicking myself that I haven't done so sooner. I'm clearly a "beginner" when it comes to using flash photography, but the Speedlite makes learning easy and fun. As I have very little experience with any form of camera mounted flash, it's hard to compare it to others on the market. With that said, I am far from disappointed with the results! As far as I can tell, everything about the flash is rather intuitive, and the recycle time is plenty for my photography. The "auto" mode is pretty amazing, and seems to be able to pick out just the right amount of light for proper exposure every... single... time.... I hesitated between going all out and purchasing the "latest and greatest" that Cannon had to offer, but found that paying over $1K for a Speedlite was rather ridiculous (not a paid professional that can justify that cost for such an accessory). It seems like 600EX II-RT will hold the test of time, and I am very excited to be able to embark in this new lesson in photography!

The GREATEST flash I’ve gotten my hands on in a long time. VERY impressed with its ability for long range type shots with an 85mm 1.4 Sigma lens

I love the flash. I’m not fond of the Mag bundle. I have not been able to stretch the rubber mount around my flash and my husband can’t either. It’s a great concept, but you better have very strong ands, a great grip, and the steadiness to prevent the attachment from damaging your flash when it slips off rapidly. I’ll use it on a less expensive, or smaller flash.

Works great! Quick recovery time. It is fairly new and have not put it through all its paces yet. But you can see advances compared to my old 580 EX.

This flash gives a high quality brilliant light that catches lots of color and helps me get my angles! Love how easily it works with my camera!

I bought 3 of these Speedlites along with the ST-E3-RT Transmitter. It's a great setup with plenty of power. The menu and display is easy to use with a day or two of using them. I used the radio link in a large room and they worked great. The only issue I found is my home Google WIFI extenders interfere with the signal. The "Link" drops after a few minutes no matter what channel I put the Speedlites on including the Auto setting. I don't think this is really an issue with the Speedlite, but it's something to be aware of if you set up in a place with devices searching for a 2.4ghz band. The Speedlites also have an optical option to fire as a backup.

Integrates well with the camera but is heavier and bigger than the Speedlite 580EXII it is replacing. Features about the same and way more expensive.

I absolutely love my new Canon 600EX II-RT flash! For years I was using a Yungnuo and I see now that it doesn't even compare! I wish I would have bought it sooner!

All around a great flash!! Puts out really clean and even light, easy to use, and pretty light weight. I’d highly recommend!

Awesome speedlight! This was my first one—I finally got tired of lugging a studio strobe around for outdoor shoots—and I don’t regret going straight for the flagship. High quality speedlight, very powerful and built well.

This has to be one of the best speedlights I’ve ever used. With a GN of 197’, it is in the same power range as my 400 WS monolights that have GNs of 213’. It works well with various softbox sizes and shapes (no problem filling 36” Octabox or 9x 35 strip box), especially with headshots and close range portraits. I use with other 600EX-II-RTs or combined with monolights and Canon transmitter. As a speedlight, it size and weight makes it convenient and useful for location shoots. I’d like to see more LEDs and color guides like the newer speedlights and transmitters have that would make it’s use more intuitive, but one does get used to it after a few uses. Originally on the expensive side, the price has been reduced recently (alone or in a bundle) which makes it a better value now. I highly recommend this powerful and versatile speedlight!

Great light, excellent TTL, wonderful flexibility.
By mlr
I have been using my Speedlite 600EX II-RT for well over 2 years and I love it. At first, I kept it on manual and was delighted with the flexibility of the swivel head and the adjustable output. These days I use more TTL and the results are pristine. I use it in studio and out, paired with two monolights vis-a-vis strobie transmitters and receivers and on the road with a Rogue Flashbender or a Lastolite portable softbox.
I need 2 more of these Great Speedlites!

This a great feature filled Flash. Leave it in ETTL and it is precise. Manual mode gives you full control. Just a great flash. Need to add 2 more.
