Not being able to use 2nd curtain with a radio transmitter is a disadvantage. Line of sight is not something that is always possible to achieve.
Just to make sure nobody misunderstood me: Second curtain sync is not possible with Canon's wireless system.
Of the three exclusive sync settings (1st, 2nd and high speed), only 1st and high speed are supported when using the wireless multiple flash systems.
I understand that some want the master/slave (I support keeping that, since in my native tounge there's no problem with it) switch back. I don't want it. I like the fact that the camera can set the mode of the flash, including normal or master. That wouldn't be possible if there's a mechanical switch to control it too, since the camera can't move the switch.
I'd like to see flash settings being coupled to the programmable (C1-C3) modes of my 40D. The flash could perhaps retain the settings from the last session in memory, if used in, say, M mode, but if you switch to C1, the flash settings for that mode should be transferred to the flash as well. At least if the settings were stored for the same type of flash.
There are issues that aren't obvious how to handle, but they can be solved, if you want to.
It would require two hands, but a simple firmware update (can't be done by the user, unfortunately) could allow holding the PILOT key and simultaneosuly pressing one of the four buttons would give you normal, master with flash, master without flash or slave. Instant mode selection, at the cost of one test flash, when you press the PILOT button. If they re-engineer and put a separate shift button there, you don't even need to send the test flash. The advantage of that solution is that a new setting sent from the camera's menu system wouldn't be blocked by a mechanical position of a mode switch.
As for ratios vs. separate settings, I prefer both. Put a general display with reasonable resoultion on the display, and you aren't limited by pre-defined icons. So instead of the A+B+C, A:B or A:B C settings, you could just add a A B C setting (all E-TTL, but with separate FEC for each group). Such a display would also easier be able to display info about even more groups, if they fit into their wireless messaging standard. It would still be nice if this Speedlite 630 EX (just a name I invented now) would be compatible with the old flash guns we have, or at least it has a legacy mode (custom function).
With this added mode, those liking front light are served as before, but those preferring all sorts of directions can use the new mode. If they have problems transferring info for yet another group (more blinking would also cost more power, just prior to the real flash release), then at least the master could have a group of its own.
