Yongnuo's 600-exrt compatinle transmitter!

Jim Saunders said:
I'd like to see Canon's apparently reverse-engineered system become the de facto standard so a camera can communicate intelligently with studio lights, meters, the whole shooting match.

I don't see any reason why Yongnuo wouldn't want to release triggers for rt older Speedlites and studio flashes, though it's duplicating their non-rt radio trigger/flash line, but if the demand is there...

What still puzzles me is Canon, they must have seen this coming, or someone just got fired for not properly encrypting their rt protocol. So I wouldn't exclude the possibility that something new is in the queue like the 430ex2 successor once the Yongnuo flash clones are actually on the market in sufficient quantities.

The other possibility might be that Canon indeed doesn't care which might be backed by the fact that the rt protocol is not very innovative other than the group mode which fixes the completely outdated/quirky ratio system - no second curtain remote, no remote zoom.

Well I could get what I want anyway but it may not last very long in a wet shoot. ;) it's pretty inconvenient to do so. But thanks for still not linking your portfolio after all this time on CR. :)
I never will for the same reasons I never have, it is called consistency, some have it, some don't.....

So if I understand correctly, the biggest advantage of the Yongnuo system over the Phottix Mitros is that it allows mixing and matching with the Canon RT system? Any idea how much these doohickeys will cost? I love everything about the Canon RT system except the price!

IMHO, the market is screaming for a radio triggering system that provides TTL functionality for Speedites, but allows remotely controlling the power (albiet manually, of course) of a studio light.

My PocketWizard setup can do that - TTL for the Canon flashes, remote power adjustment for my Einstein 640 via a PowerMC2 (or semi-auto, with power tracking where it automatically compensates when I change aperture or ISO).

What I'm clamoring for is a Canon RT-compatible receiver that allows simple triggering of a monolight...

If the Yongnuo st-e3 cost less than $200, I got 2 600 ex-rt that will appreciate it :)

I was thinking EXACTLY the same thing...I've got 2x 600's...and am dying to be able to take one of them off the 33' sync cord, and have them BOTH run wirelessly.

I'll be getting one of these likely quite soon if they look as good as they sound.

Can poor people (like me :)) who use Alien Bees/White Lightnings also benefit from the MC2, or will they only work with Einsteins?

Only Einsteins. For AB/WL, you'd need a FlexTT5 tranceiver and an AC9.

It would be badass if you could have the benefits of the MC2 built-in to the FlexTT5, but then Speedlite users would complain that they're paying for something they don't need. Kinda like the "I don't need video on an SLR" whiners ;D. At least Pocket Wizard gives you the option of adding on studio light power control to its existing receivers with the MC2. Pretty cool!

Actually, the MC2 is really a dedicated unit. It plugs right into the top of the E640, using the same pin connections as PCB's CyberSync unit.

But the AC9 is an add-on to the regular receiver. The MC2 is a nice deal, in that it's standalone and costs $100, whereas to integrate an AB/WL monolight into the PW system, you need a FlexTT5 and an AC9, which will run about $275. That means for existing PW users, getting an Einstein is cheaper than a B1600, and less than $50 more than a B800.

Makes you wonder what sort of conversations are happening between Canon and their litigation lawyers.

Probably none, because they figured out that they cannot prevent clones long ago, less so if they aren't 1:1 optical copies.

Of course Unless covered by a patent, but the rt protocol wouldn't fall under that as the Samba folk reverse engineering Microsoft's network protocol showed. But Canon could converse with their technicians to add a (stronger) protocol encryption next time...

Microsoft was forced to open its protocols by antitrust investigations. But look at how Apple is protecting every patent it can enforce, even silly ones - but it sees Samsung as a real issue to its revenues. Maybe Canon thinks it would cost much more than lost revenues, especially since it's a Chinese manufacturer, and without an US or Japanese company to go after it could be very difficult to sue them. although this is really a 1:1 copy looking exactly the same, and I guess this is a real infringement of many copyright rules.
Encrypting the protocol won't help much unless you can protect encryption keys strongly - you need anti-tamper hardware to do it, but it can be broken as well if you can access that hardware (as the PS3 protection was broken). Also stronger encryption needs more powerful chips to be performed on-the-fly, and they could be more power hungry.
Anyway I don't like copies, no matter how much cheaper they are - copying is far less expensive than developing from scratch - and it's not compatibility, which is something different. It is true that Canon started copying German cameras, though...

Samsung is a South Korean company.

Also, I'm sceptical this Yongnuo transmitter is real. It has been suggested that it might be fake.

What are you using to trigger the MC2? I know there is a Paul C Buff Commander system that also allows remote power up/down from a central position too.

It has a US branch - which has to comply with US laws - you can sue (and any outcome is valid only there). If it had not one, just reseller, you could sue resellers maybe, but you can't sue a foreign company in your country, you may have to call in WTO or the like, but a court jurisdiction can't go beyond a nation borders, some agreements may let you to do something more, but it works in systems like the EU or the like.
Here in Italy Turin court tried to judge a Chinese company for selling counterfeit goods - it has to ask the Chinese company to declare a domicile in Italy for the purpose, because the laws requires it - you can guess what the answer was...

If it's a fake of course Canon doesn't matter - but if it was not, it could be difficult to enforce IP protection in some countries.
