RCederholm: Love my Odin's for Canon. Works great with both my 430EX and 420EX. It is so great that one can use the older flashes with them. Just a great system.
That said, I do have a few gripes (one which is fairly well documented with users). The receiver unit is fairly large in the front and I find it difficult to use it for softboxes and get the flash head in the enclosed area. Usually have to turn the unit, which then negates the ability to use the zoom feature. Also, I've heard that the units send out a pre-flash which make it tough to use a meter. Lastly, as compared to the Canon unit, the transmitter sits quite high, which likely makes it easier to knock into things.
The stated negatives are things I can work with and I do truly love the system. It was a lifesaver when I had to shoot a wedding solo earlier this year and allowed me to get this shot within a 5 minute timeframe (which is all I had):
You mention the problem of the units emitting a pre-flash. If your'e in E-TTL mode they have to, by definition.
It would certainly be nice that if you're working strictly in manual mode, no preflashes would be emitted. At least that's how I would expect it to work.
plevyadophy: Just received a reply from PHOTTIX.
It appears that their product, contrary to the impression given, may work only with camera bodies that support ETTL-II, and not the original ETTL.
That sounds odd to me, because I thought that E-TTL vs. E-TTL II was entirely in the camera, and that the flashes didn't know, or need to know, which system was in use.
I mean, a 550EX works with E-TTL II, doesn't it? Yet it predates E-TTL II.
I'd love to know why and in what way Canon modified the camera-to-flash protocol to accomodate E-TTL II, and how this causes problem for a system like the Phottix.
BaldCol: Canon probably didn't test using auto metering for long exposures in the dark with the iluminator on because they did not think anyone would be stupid enough to do it.
I'm off to test my 7D metering while shining a torch in the viewfinder so I can see it better.
Hey, make sure that's a British torch and not an American.
