Lighting / Re: ST-E3-RT & 600RT with Canon 5DIII
« on: September 28, 2012, 08:41:48 AM »
This is exactly what I did. I replaced the two 580 II with two 600s and the st-e3-rt.
For me the biggest plusses are:
Easy of use, everything can be driven from the camera (1DX), for example changing to HSS, just do it with the camera menu and the flashes change straight away to HSS. With the 580s you had to change it on the flash as well.
Radio control is a real plus. I use the small lastolite softboxes and was always cursing the line of sight issue, I mean the the soft boxes were "blocking" the optical transmission.
Radio control works fantastic, I put one behind a car and it happily fired.
Another (minor) plus is the extended zoom to 200 mm with 600s.

It was a lot of money to change, but as far as I am concerned, it was worth the money.

I have had great success taking pictures of watches using the focus stacking technique.

Please have a look at what the Helicon guys have on offer

please check

it shows that center is best at F4.

borders stay poor throughout the range.

Even the 50 F1.8 has better border performance.

Huhhm, 24-70.

I do have an issue when the lens focusses on a far away object, close by is fine.
I read an article about field curvature , see :


Now that I know about it, I notice it almost always when making landscape. Manually focussing on "hyperfocal distance" solves this problem.

Bought a TS-24 for landscape.

Anyway, in day to day life , I do not have a problem with 1DX 24-70 L (mark 1). It is spot on apart from the phenoma described above.

The first 24-70 where notorious as there were many bad ones among them????

yes, the 600 and 580 II will working together, but only in optical mode.
I have sold my st-e2 and two 580's and upgraded to st-e3-rt and two 600.
Sofar, I have been able to set everything that I needed with the camera menus. For example, set to HSS on menu and slaves will switch to HSS. With the "old" 580, I had to do an additional step: set HSS on the flash as well.
The on flash menus are so MUCH easier to use on the 600.
It was a bucket of money, but it sure is worth it.
I will need to spend more time to explore all the additional functionality, which is a lot.

Most important for me is the radio triggering, no more need for line of sight, which really helps when you use a small softbox on the flash

Any comments on the "focus field curvature" that is very apparent with the version 1 at 24 mm?



Lighting / Re: EX600RT with 7D and 60D HSS
« on: September 06, 2012, 07:45:51 AM »
Hi Diane,

did some tests, not sure if you will not like what I have found.
7d with latest firmware 2.0.0.

ST-E3-RT in hot shoe, is recognised by the 7D as a "dum" device. It will trigger, but you can not get enable wireless.
EX 600 in hot shoe of the camera. Manually set the ex600 to radio control. Switch both 7D and Ex600 on.
Go to "external flash setting", enable wireless and the ex600 will switch automatically to optical.
After that I set ex600 manual again to radio control and it will trigger via radio the slave.
Switch the lot off and you will have to go through the sequence again.
Next issue: normal sync speed is 1/250 optical, but 1/125 radio controlled (says so in the manual!)

Next experiment, I have the wireless enabled on the 7d, manually set both ex600 to radio and HSS.
I am able to set shutter speeds to 1/8000 and I get proper exposure. I tried same shots with optical and exposure is the same.

For me, the biggest draw back is that all the functions that you have when using the ex600 in optical, so define ratio etc with the 7D menus, is not working in radio mode. You can fool the system by steps outlined above.
So, back to you original question, from my test it appears that you can do radio controlled HSS with the ex600 but you have to set it on the EX600.

Hope this helps


If you want more detail, just send me an e-mail

I do have a 1DX, 7D,  two EX600 and a ST-E3-RT.
I do not have time now, but if you can wait a day or two, I will do some High speed sync test with the 7D.

Hope you can wait

Hi, just upgraded to 1.0.6.
I noticed that after formatting  a Lexar 32 GB the number of shots  (R+jpgL10)is now 665, and it used to be around 800 shots for that card.
I loaded an empty "old" card which gave me a free shot count of 807. I took one shot and the free count went down to 664
Did anybody notice same?

I noticed the back focus problem before, but I tought it was my own stupidity. I will try later this week

Technical Support / 1DX, ethernet on MAC
« on: August 01, 2012, 09:46:31 AM »

I have tried to setup an ethernet (RJ-45) connection between my 1DX and my MAC (lion). So far I have been unsuccessful.
I have tried both the FTP and EOSUtility options (2.11.4). My MAC clearly recognises the camera and assigns an IP address on the fly.
I am using the recommended cable a cat 6 twisted pair
Has anybody tried this?

I am using 2.11.4 on Lion (so, not mountain lion) and it works via the USB cable, but not via the RJ-45 LAN cable.

Thanks for bringing this up.

I had to wait for several months before it worked on Lion, so I am (was) reluctant to upgrade to Mountain Lion.

To everybody who is still waiting for their 1DX.

I have been waiting, waiting, waiting ...... since March.

Fortunately, I finally got mine this week (Perth , Australia) and within minutes of using it, I forgot about all the pain of waiting, calling the suppliers etc...

The 1DX is as good as it gets !!

So, just hang in there, once you get your 1DX, the pain will be over and you will have the time of your life
