Interesting... don't they normally have an upgraded version in place well before the EOL for a particular product is announced? Just an observation.. could this mean that there will be no direct replacement for the 7D?

When a model shoot is going really well, I like to click about every 1-2 seconds. I was hoping that with the speedlight on manual at 1/2 or 1/4 power, that it would keep up, but it didn't. I lost about one shot out of every 3 or 4 when it didn't fire. That was with alkaline batteries. I later tested with eneloops and it worked a little better.I think Yongnuo has minimum 2 sec between shots regardless of power. I think I read somewhere this is a tech spec of the flash they produce.
Not that this matters... but I have been thinking of upgrading my 70-200 F4 to a 2.8. I also thought about upgrading from a MK II to a MK III instead. So I took 3 of my lenses...
I was able to find a spot in a dark area that was difficult to focus and then attempted to focus on that area with all three lenses.
I used both the 24-70 and 70-200 at 70mm and I moved up slightly for the 50 1.8.
Now I am not talking about focus accuracy... simply focus lock. In my results... which I didn't expect... here is the order in which the lens performed the focus lock the quickest.
I thought it would be exactly the opposite.... can anyone explain?
So the 70-200 was fastest, 24-70 next, and 50 f/1.8 slowest? That's a 24-70 v1?
I'm not surprise the 50 f/1.8 was the slowest. While it has a faster f-number, it has a slow and old AF motor, and it's actual transmissive qualities may or may not be as good as the rest. Which that can certainly matter, especially in a location with a low amount of light.
