Does the Test Fire button on the Yongnuo YN622C act as a standard wireless shutter release?
1) Can you half-press the button to make the camera Auto-Focus, and then full-press the button to take the shot?
2) If you hold down the button, can you shoot in continuous burst? (assuming no speedlight mounted, so no power cycling cooldown)
Basically I'm trying to figure out if the button on the YN622C acts exactly like the camera's shutter button.
I made a similar thread regarding the Canon 600EX-RT at http://www.canonrumors.com/forum/index.php?topic=18425d
A poster replied that the 600EX-RT's release button has neither of the two functions I asked above.
The problem I'm trying to solve is that many standard wireless shutter releases (e.g. Satech WRT-A, Vellos Wireless Shutterboss) require a receiver brick to cold-mount onto the hot-shoe, which means I can't mount a speedlight onto the hotshoe. I am trying to find a wireless shutter release solution that allows me to have a remote release button that acts exactly like the camera's shutter button yet allows me to have a speedlight on the hotshoe at the same time, should I have need to.
