Let me be more precise: i dont' consider canon to be greedier than other corporations. I perceive them to be more shortsighted with greed. All they only offer is what is absolutely required to not loose out to competitor's products immediately. Sometimes they undershoot that threshold. E.g. Eos-m.
And even when canon comes up with a new feature like switching from line-of-sight-triggering to radio-wireless that is hugely useful to many customers and leapfrogs the entire competion, they are held back by shortsighted greed. Only offering rt in one expensive top of the line speedlite and one commander that lacks in other features. And they design the system to deliver the goods in combination with the latest cameras only. Rather than really pushing the feature unto rheir huge installed base (of pre 2012 eos models and 580/430 speedlites) by offering a 450ex-rt and a cheap little transceiver for existing canon speedlites. Of course canon gets punished for this behaviour by amateurs like me who do not need to have the rt system to earn money.
So many amateurs like myself have held off totally from paying canon 1.5k for 3 600ex-rt and an st-e3. Any day now i will be able to pick up a yongnuo ste of rt-commander plus rt-flashes and transceivers offering more functionality for about 1/4 of the money. And it will work nicely even with our pre-2012 cameras - even across makes.
Now who is the winner here? Certainly not canon, who have invited 3rd party competitors in and have not leveraged their technological improvement to really create a full-sized USP against their direct competition. Nikon or sony have gained valuable time. Canon has no killer instinct. They may lead in sales at the moment, but they dont lead the market. They don't ever try to exceed their customers expectations the way nikon or sony do ... On occasion. Canon really is a follower company. They will not win the game long-term with the attitude they have been showing over the last 5 years. They are trying to nickel and dime their customers exactly in the same way gm and ford have tries to. Withholding even small and cheap pieces of technical progress like give me a break - wifi connectivity in a digital camera. The strategy will not work for much longer.
Due to canons decisions i have also held off buying a 5d 3. and the 24-70 ii that i would take to go with it. I am continueing with my 7 d for the time being, and will sell the 10k canon glass selection (ef, l, ef-s) as soon as i get a 5d 4 type camera as a solid state milc. By whomever.
And no, its not just me. Its many other "enthusiast/amateurs" too. :-)
what i don't get about this whole argument here is this ---There IS and HAS been a thriving third party radio trigger business for quite some time now.
Think about it, what is the industry standard for triggering strobes (not just speedlights, but all forms of strobes) - its Pocket Wizard. That may be why canon isn't pulling out all the stops on this....
Also, come on guys, have some patience here. An RT receiver may very well be around the corner. Or, it may not be!!! The problem is this, and this is where i get the idea of testing the waters. As said above, the industry standard is pocket wizards. Canon not only knows this, but, they also know there's more than one way to trigger a flash. A lot of shooters pick and choose where they need the latest tech, and many do prefer the simplicity of manual flashes. Manual flashes are generally a lot cheaper and pretty reliable because it's not packed full of tech. Then there are others who choose the cheaper option because they can't afford the switch to more complex systems.
For like just shy of 2 years now i have been using the cheap triggers...cactus v5's. Basic, simple, BUT reliable!!! I had one that took such a bad fall it tore the top hotshoe off. that one still works!!! not as a receiver of course, but the bottom shoe is fine. when i got them i got a batch of 5...one of them has died, but, for $35 a pop I'm really surprised more of them haven't died....
And there are a ton of other pretty reliable cheap options, and you can scale it up even too to less cheap options until you get to the odins and PW Flex and radio poppers.
So, I think it is actually a VERY wise Business decision to do what they have done with the RT system.
If your buying into the RT system, it means you want more than basic manual functionality. And if you want that, you know your spending more $$$ to get it. It's just the nature of the beast. Canon knows this. So they introduce it in their flaghip flash. It's sensible. those that want what the new system can do will buy it. Canon does not need to make a work around because ---most of the people buying into this system already have a way of triggering flashes!!!!!!
I use myself as a test case...as I said, i have my 4 cactus v5's. They are old and i want to replace them, or maybe move to the phottix strattos ---- or, make the leap to the RT system. Flash history. I had 2 580's and a 430. But one of my 580's got stolen. Ended up replacing it with another 430. Then, the night before shooting a wedding my last 580 died. No time to find another 580 on ebay, or order anything cheaper, so i snagged a 600.
the sale has me tempted, but, I know I could replace my cactus's with strattos for less than it will cost me to buy 1 ST-E3. I have grown used to manual settings so I don't know if I really need ETTL. That, and, I kind of like being able to have an on cam flash as well as off cam (just for a little fill). So, the new system for canon may not be best suited for me.
There are tons of options out there, and canon knows this. They made something unique and those that have adopted the system like it enough to say great things about it. Hell, great enough to even temp folks like me who like me! Hell, I may even buy the strattos but still get the ST-E3!!! LOL
