Default Speedlite 600 ex rt & 580 ex ii

Hi, Folks.

I was planning on buying the 600 ex rt flash to compliment my 580 ex ii, but 2 people already told me that they are not compatible, I haven't tested or tried it & the salesperson at the store did not help me that much because he is a nikon user & he has no experience with canon flashes

Is this true?

compatible with optical triggering but not radio from 600 to the 580.

Honestly I'm not 100% sure. If the cactus V supports ettl then yes. If your goal is to shoot manual flash then get a cheap triggering system, if not then 2 600exrt is not a bad way to go and avoid radiopoppers etc. I personally use 4 600exrt and an ste3rt but two would do the trick for alot of folks. What are you trying to accomplish with a 600 that you cant to with a 580?

Actually, I only have 1 flash & since 580 ex ii has been discontinued, I don't have a choice but to get the 600, & I don't want to get the 430 ex ii, as it is a step backward. I am getting an additional flash so I can use 2 light set-ups for my small studio, & eventually get a 3rd one later which is obviously will be the 600 again.

I have both a 580exII and I just purchased the 600ex-RT. I also used (and still have) cactus V5 triggers. The cactus trigger will fire both the 600ex and the 580exII. Just remember that all the cactus V5 is doing is firing the flash, so you don't get all the handy stuff that you get with the built in radio transmitter in the 600ex.

So, it kinda' defeat the purpose of having a built in radio trigger in the 600 when pairing the 580 on a cactus V?

How do you set it up, the 600 & 580 with the cactus, 1 cactus on the camera flash mount, 600 no cactus & 580 on 1 cactus? Will this work? If not, then I will be needing 3 cactus Vs, am I making sense?

It does defeat the purpose of the radio trigger if the only two flashes you have are a 600ex-RT and the 580exII. Since the 580exII does not have a built in radio function and Canon has not said anything about making an adapter for older flashes, you need a third party system such as the Cactus V5 in order to trigger the flashes.

You would set up the flashes the following way:

- 1 Cactus on the 600
- 1 Cactus on the 580
- 1 Cactus on camera hotshoe

All flash settings will have to be set manually at each flash since the Cactus system is just for triggering the flashes using a radio signal versus an optical one.

I agree, if your just looking for a flash to fire manually with a radio trigger then I'd highly recommend against getting the 600exrt. Its a waste of money unless your trying to utilize the radio technology. Your better off getting some nikon sb-24 or sb-28 at a fraction of the price and getting some cybersync triggers. If its for studio use, I would not recommend the 600exrt if your only goal is to just shoot manual flash unless you have tons of cash lying around.
This would do the trick for 47 dollars if your shooting manual flash in a studio, you just need to get some inexpensive triggers then.http://www.adorama.com/US%20%20%20%20537795.html

u might as well sell the cactus and the 580 and add bit of cash to upgrade to a 2nd 600. u gain ETTL on both.
sold my 580ex2 and got 2x600

The abilities that the 600ex-RT offer you in their radio system are very nice. The only thing I wish it had was the ability to adjust the zoom of each flash independently from the master unit located on the camera. The ability to set ratios and the new group function if you have a 2012 or newer Canon camera are quite nice I have been using a three speedlite setup for my purposes on a non-2012 body and it works very very well.

If you are looking to go to a three speedlite setup within the next year, I would go with the 600ex-RT and work on getting a couple more. Keep in mind though if you wish to do three speedlites off of camera, you will need either four 600ex-RTs or three 600ex-RTs and Canon's speedlite trigger that has the built in radio transmitter.

You have some options:
A) 600EX-RT is fully compatible with 580EXII in optical triggering mode. Essentially the same flash.
B) 600EX-RT(s) and STE3-RT will provide radio triggering with Canon cameras. There are limits to the capabilities is the camera is pre-2012. If your camera offers speedlite control menus on the LCD all the capabilities with Canon radio triggering will be accessible.
C) Manual off camera flash via fire only triggers. The 580EXII can play, the 600EX-RT can play, just about any flash that can be configured for manual control can play. The triggers will only fire the flash. No ETTL, no HSS. One benefit is that these flash units are inexpensive.

It would make no sense to get a 600 unless you can sell the 580 and just get two 600's.

I would look into a used 580 if you don't want to sell the 580 you already have.

You can still purchase the 580EX II from B&H. They still have them in stock.

If you purchase the 600 you will get the RT bug . I purchased one because I needed a new flash but it did not take long to sell everything and get more 600 flashes and the ST-E3-RT.
