Seems HK post office is super slow. I believe that Mainland China is way faster. I had 3 items from mainland China come to California in 7 days. For HK its 3 weeks or more.

I got 3 other packages from China, ordered on 09.10 too...This other 3 was 3 weeks max.

I checked mine, their status changed to "Item sent abroad" at last night. :D

Is anybody knows where can I buy a new foot (with pin style contacts) for my 580EX IIs? Every seller on E-bay offers an old style contacts (as I saw on the photos) what I already have.

They really are. I love them. I had Yongnuo's version of the ST-E2, but didn't follow through with learning to use OCF. But, with these, it's pretty fun. I'm learning a lot with them and hope to pick up another couple of flashes this weekend, followed by two more of the 622C's.

So along with my studio strobes, I'm using a 580EXII on a boom with a strip light for a hair light. I've got a 622c to fire my studio lights and another to control the power of the 580EX II up on the boom via the camera menuing. Deluxe, simply deluxe.

I used the 622's for an event this weekend, and the triggering and operation was largely reliable.

I had one issue where I had accidentally touched the channel button and switched receiver channels, causing no firing which took a couple of minutes to figure out. D'oh!

The only point I had a few problems was where the remote flash was about forty feet away with a fairly large crowd of people in between it and me. There were a few issues with triggering - I'd see the flash go off but the exposure wouldn't have much flash component. I wondered if I was getting those timing errors I'd experienced this week in testing. I can't say that this was down to unreliable triggering, as there may well have been other issues going on (people in front of the flash, flash recycling etc) and I was also getting missed shots most likely due to flash recycling issues. But it did give me some undesired behaviour to work around.

The weirdest one that happened a few times was that I'd be getting the exposures I wanted, then the flash would get really bright (like a full dump) for one shot and then die, not firing again at all until I faffed around with FEC down to a minimum and brought it back to life, upon which it would go back to firing normally as expected. Again, not sure what's going on here, it's difficult to troubleshoot those things during an event situation, and as it's the first time using remote ETTL flash at an event, I was expecting some oddness. I did switch to manual after some of these quirks which seemed to help a bit.

All in the process of understanding the behaviour and performance of the system so I know what to expect going forward...

Turns out a gripped 7D + 622 + 580exII + 70-200 2.8 IS MK2 is BLOODY HEAVY! Who knew?!!

Hi,

when the flash was 40' away, was that in group C - set separately on what? or were all flashes on ETTL ? What was the subject distance from camera and flash units.

One flash, EX5800II on Group A. This was indoors in relatively poor light.

Like I say, I was on ETTL at first, and flipped over to manual later on to try to combat a little bit of unreliability in shots.

What was the subject distance from camera and flash units.

Subject distance about 20' I guess, I think I was about 1/4 power on the flash, in that range any way. Exposures were around 1/60th f2.8 ISO800. In the metadata, LR always has "Flash did fire" whether or not the flash actually fired in the shot - I'm not sure yet what to make of that...

I'n not an expert like Clive, but it sound like the distance of flash from camera was to great for ETTL to work efficiently. If you set the flash power to 1/4, it may have affected the ETTL as the 622C is supposed to adjust the light strength itself.

Are you anywhere near the Midlands area? If so we could compare notes more easily as we have similar equipment.

Malcolm

Sorry, I think you may have been referring to 1/4 power in Manual.

Hmm, shouldn't be. The camera just meters the scene and works out the flash power and transmits it to the remote. It's only a problem if the flash can't deliver enough power for an acceptable exposure, which wasn't the case here. Distance shouldn't be an issue as long as communication between the triggers is reliable...

Yeah - I meant, after a bit of weirdness with ETTL, I flipped the flash to Manual mode, and changed the power level to give me a good exposure (something similar to what ETTL was giving me). This was around 1/4 power.

Nope, I'm in London I'm afraid...

It does matter. ETTL works based on a preflash from the unit, just prior to shutter release. The camera meters the returned flash and decides the power from there. So, distance from flash to subject to camera and, any obstructions along the way, makes a difference. Please correct me if I'm wrong. I'm just learning of camera flash, so my understanding may not be accurate.

Of course, that is how ETTL works.

I mean, assuming there is enough flash power, it doesn't make a difference whether the subject is two feet away or thirty feet away - the scene is metered as you describe to work out the output power to set. And as I mentioned, the subject distances are not a factor here - so for the purposes of the discussion about the odd behaviour, it's not really relevant.
