One last question in regard to windows going to be subscription based. Am I right by saying that Mac OS is already a bit like that. Although buying the computer provides you with a lifetime subscription...

The announcement says it has a panning mode for the stabilizer. That alone seems like a big plus over the Tamron.
I never, ever, use panning mode on my 70-200/2.8. And I shoot thousands and thousands of panning shots. Mode 1 just works better for obvious reasons - it stabilizes in both directions instead of just one.
I'll be waiting on this one, not because of specs, but because my finances dictate that I won't be replacing my 7D until early 2016. I should be up to 110K exposures by then, which seems like a good point to make it may backup body. Who knows, maybe by that time Canon will have come out with a 50MP camera with a built in coffeemaker and a unicorn for $500.
In any event, it looks like I will have to have plenty of napkins on hand to wipe away the drool for the next 18 months.
Built in coffeemaker AND a unicorn! Bet it also makes rainbow flavoured popcorn! Sign me up! LOL
Isn't that working just because the whole process of taking the picture occurs within the 1/540 s of the full power flash duration? If so, it is not really high speed sync isn't it?
Correct, but it does equate to faster sync, it isn't HSS, it is what Pocket Wizard call HyperSync, the trick is to get the flash to fire before the second curtain starts its travel, that is what causes the shadow, the second curtain, so if you can adjust your triggering time to sync not when the first curtain is fully open, as in normal sync, but before that, just before the second curtain starts to close and your flash duration will last the entire exposure at an evenish value then you get faster sync.
But what it should more accurately be called is second curtain sync above true sync speed, but SCSATSS is nowhere near as cool as HSS or HyperSync!

If so, it is not really high speed sync isn't it?Longer flash duration during shutter travel is exactly what HSS is. There is not other way to do it since there is no point in time during which the entire shutter is exposed.
The resulting flash power must also be quite low as a 1/8000 s the exposure would only capture about 7% of the flash duration. Also, how constant is the flash exposure? As a flash output is far from linear, my feeling is that a small change in timing might result in quite a change in exposure.
I'm only starting of with flash photography and that's only me thinking out loud here. I was just wondering...
No it isn't, HSS is many high speed pulses timed such that the entire shutter slot gets even illumination; not one long flash buts lots of very short flashes. These tiny fast short flashes effectively emulate one longer one, but at the cost of much power.
Have you tried putting a much longer shutter speed on to see if it is just a sync issue
Ok thank you all. I think my flash is definitely dead.
I did some other tests.
I did all the settings Dekaner told.
I have no wireless settings (flash is not compatible). reset settings, ttl, first curtain, etc..
Here are my new tests:
1) pmode. No flash, then Flash.
2) manual settings, underexposed photo. Then flash with manual power adjusted to 1/1. And flash exposure compensation +3. I saw a very little strobe. and the photos comes completely dark, like the one without flash. The only difference is the white balance (warmer with flash activated).
