<span style="font-size: 9pt; color: black; font-family: Verdana;"]I agree, it seemsthat at leastthe higher end cameras should have this function included. The Nikon CLS system can use the onboard flash to trigger remote flashes. The 580EX uses visible flash to trigger slaves (the ST-E2uses "near infared" light). It seems that it would then just be a firmware fix to get the same functionality the CLS system provides to a Canon body <span style="font-family: Verdana;"]BUT, keep in mind it is still an optical based system and all of the other problems you have with the Canon Wireless System are true with CLS and would continue to be true if Canon moved in that direction. <o></o>


<span style="font-size: 9pt; color: black; font-family: Verdana;"]Now,a native Canon Radio Frequency (RF) System would be the real bee's knees.


<span style="font-size: 9pt; color: black; font-family: Verdana;"]I prefer lessgear and a simpler setups. Some setups I read about sound like working with legos. Except for the outrageous cost the 430EXs,ST-E2andImpact Digital Flash Umbrella Mount Kit from B&amp;Hcost about the same as one Quantum Flash.<o></o>
