--ok, I dont use that feature anyway, but it's kinda limitating as a serious camera...--
Here is another way I thought about looking at this. There are three different ways Canon has to trigger OCF. If you compare each method and relate them to different levels of standard zooms it would look something like this:
1. Pop up flash triggering - 18-55IS
2. IR master ie 550ex, 580ex, ST-E2 - 17-55/2.8
3. RF master ie 600ex, ST-E3 - 24-70/2.8 II
The 18-55IS will produce great images, but if you are ready to step up your photography to the full frame level of a 6D, would you, if it were FF campatible that is, still use that 18-55? Maybe at the 6D level, it's time to step up the OCF triggering to the next level too.
