I hadn't ever thought about the Minolta flash meter being fooled by the ST-E2 (mounted on-camera) infrared signals. But since an optical slave (plugged into my non-550EX flash unit) can be fooled by line-of-sight ST-E2 IR signals, then I conclude it's possible the flash meter might be affected too. That's a good thought, and I'll test it.
I don't ever use my ST-E2 off-camera, to serve as a remote camera shutter release. And thus I don't ever mount my 550EX flash on-camera, but have it in 'Slave' mode - that doesn't seem to make sense. Seems like an awfully expensive remote shutter release system.

Have you measured how much lower the output from ST-E2 alone is if you compare that to the 550EX full power? 2) If you set an ON-camera 550EX in SLAVE mode and let the camera exposure meter go off (6 second timeout) will the ST-E2 trigger it (hand-held)? * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
