I don't care acon , what that matter ? I am not paid! I care fact and justice.
I felt I have some interest to pull out conspiracy like "one man many role", "self ask self answer" as I discover in a "forum" I don't want to mention here.

Thank you. I understand the test is personal test and relatively, rough.

I have no mean to know who is employee who is not. I just expressed my opinion about that. like compare the words style of the 2 IDs.
You should know there are many one man many roles play if you examine with careful eyes.
You are so keen to learn personal and I gave a frank answer. no because I expect the "respect" as you to "Class A". but I don't think it is polite to ask the personal question again and again.
And because you have swear you are not Paid under the name of your God. Or anything you are to swear under
So I gave the direct answer. which I feel quite offensive.

Now it is your turn ... what is your connection to Acon?
I am asked but not paid to convey test against the mis info by many IDs.
I am provided any info or data from acon.
I did it for curiosity and justice.

[ClassA]
I'm mainly looking for confirmation that Andy888 indeed uses the R930 in a remote power control situation and still avoids the pre-flash. If he is not, then he is not doing a fair comparison. If he is, I'll get back to Cactus and tell them, "Look, there is a way. You should try harder."
[paulster]
My other question is whether the Acon can genuinely do something that the Cactus (and seemingly every other trigger out there) can't do, which is to control power manually from the trigger whilst avoiding the pre-flash when the flash is in TTL mode. If Acon have cracked this then I'll be pushing Cactus to up their game and follow suit,
I note the words style again. and I said it last, use ONE ID to ask question,

Not swear and, Honestly. ..
I am open for critics, and I gladly added the UI video for your request. Because I stated "fair".

Shill is better than you.^_^
Happy new year to other viewer.
Because you swear, It should be understood that base on your religion, for example for Cantonese, under the name of the one you love.
I don't refuse but you should go past test because you challenge me.
[BTW, it is Class A asked the same "functionality" exactly like this ID and same "ask cactus", So you both seems the same people, who accuse other as shill...

So right here, the man behind ID paulster (whom I belive is ClassA ID owner), Swear, Base on his religion, (if he is of Cantonese, under the name of the one he love). said that words with swear...

You or ClassA，are more suspicious related to Cactus. Why not just swear too to help the answer.

Fine,Clarker swear under the name of God.

1/3 past. who is next!?
---------- Post added 12-31-16 at 06:28 PM ----------
This ID, come by owning a 645Z, then go to the topics...
Well, carefully examine the ClassA, (who come from Cactus's own forums and actively explain things, who state "not connected")(state New Zealand),
this ID(state USA)
word styles...I suspect you are the same man behind.

Who ever behind the ID.
I am so seriously suspicious you to be paid to speak unfair too. for you challenge me .
You should one by one go through the test. who is first? swear under the name of God. or anything he make as "God", who?
Swear you are not paid to challenge acon or me? Who? come out. Swear yours first, then you can challenge me.
----
I made so many video and make test, to prove fact. because I tired of words without stuff.
which you ( no matter IDs or person) would not face be turn to personal.
Base on personal but not test result or anything else to "debate", I don't like to do this.

Whoo. I don't think I like to response to affensive from any "strong users", BTW, I would like to response to one ID only. thanks.

I have interest in research for paulster. and Class A.
Since I felt Class A style in paulster. So I read his post carefully.
Well, I don't believe this ID is a native american.
All around cactus product. That is , OK, fine. and Class A English style, alike. carefully type and , not native feel. Since I response to Class A many times. I felt this.
OK. this is , my felt.

Well, light meter is rarely used by most, indeed for modern camera with very good light meter inside, and advanced TTL tech for flash.
Which you called "not advanced than manual".
Funny, When using Manual, you again attack the light meter for manual people.
I would not use manual without a light meter. it is very painful to do 'again and again mess'.

From my usage I find the 930 cover the 62， and provide TTL and optical and real manual. that is why I abandon 62.

Whoo， I don't think class A will. He seems very skillful commenting things he never use and called for , FAIR.:)
BTW, I don't think acon should reverse engine the V62, which is too buggy.
So I decide to sell out the V62 and keep the R930. because I just can't bare using so many triggers to do the same thing.
Although the V62 seems with a lot more control while the R930 with quite simple control. I don't think I can give up TTL and do painful manual always with camera M. and real manual and optical capability and many many lively functions to exchange for a hard dial and LCD. I have enough of them.
More over, when it comes to my 3 pentax flashes , I can't imagine using this 4 big guys, I prefer using a acon receiver and walk to others, which set as optical slave. with radio optical mix.

I can confirm the V2II is fake Manual.
Fake is not the end. unreliable, some misfire , OR, power out of control,making the "advanced dial and LCD" useless.
I heard enough about this V6II as "Manual is advanced", and debates.
So I would like to have that for a "research".
The outcome is unexpected. disappointed.

These was measured by simple oscilosicope, an electronic tool.
The shutter speed for 1/320 to 1/8000 is HSS, this isn't the same as what happend in Chapter 1. I would mention in other Chapter.

I collect these triggers and I expect a reasonable, fair, and scientifical test for all of them.
And they arrived.
I am not to intentionally specify which is best but I would like to have many chapters and make marks. As so many debate here about this topic. I think this might help people to make clear understanding rather than by heard on the road method.
CHAPTER 1 TRIGGER BASIC
OK, first things first. Triggers, or radio triggers. No matter how complex they can be, basically, they are used the fire the flash as quick as possible as the camera tells it to do. for normal sync speed. for example, Pentax 1/200 second max. and Nikon 1/320 second.
At the right beginning, the front curtain of the shutter open, the CCD is exposed to light. the flash fire, have the light reflected to the CCD. this last 1/320 = 3125 uS for Nikon and shutter speed 1/320. and CCD exposed last for this long time. the rear curtain close the exposure.
So it is clear, if the flash fire after 3125 uS from the first curtain open. I would not give light to CCD.
The radio delay, Should come from the electronic circuit. circuit processing need time to be done. I call this as speed of radio trigger.or trigger delay and this figure show the delay data for each of these 3 triggers.
From the above, We learn that, third party RADIO trig isn't an ideal tech. for it simply have the delay. while a wire or ottical would make no delay.
this make effect when shotting moving object, it is impossible to mimic a wire or optical trigger.
Though, How it matter the camera processing isn't known.
The delay should be as short as possible. I give 4 star for R930, 3 for X1N, and 2 for V6II.
CHAPTER 2 Manual Fire
All 3 triggers are able to set manual flash output. The use similar tech. first, set the flash to TTL-Hss mode., they mimc the TTL to set a power level.
The question arise: is this manual power the REAL manual ? If you exmaine the photo taken, yes the power have been set.
But, further examination make me so suprised, and I classify them in to 2 kinds.
1) Real Manual. this make exatly the same power like setting the flash to manual mode.
2) Fake Manual, this introduce some other preflash, this waste power and most worse. impossible to use light meter.
figure 2-1 for fake Manual trigger, firgure 2-2 for real Manual. Set the camera as the parameters suggested by the light meter.
another one: http://i1.piimg.com/4851/903a437a3f09a26e.jpg
2-1
 another one : http://i1.piimg.com/4851/cca67f84bb5df78f.jpg
2-2
The V6II make fake Manual and R930 make Real.

CHAPTER 4 Multi Brand
Multi Brand makes it possible for cross brand usage, Both R930 and V6II claim supporting M.B. But actrually, due to this tech complexity, It seems easily introduce problem. I don't have all models for test, but accoding to the SB600 I have, which supposed to be supported well, It is.

Some studio flash use the 3.5mm port to let triggerring. So the all 3 seems to have such function.
