The tea was good.
OK, the 320EX cannot act as a master. I tried it, to be sure.
The one big reason I recall Syl Arena not liking the ST-E2 was the economics of the device, as it costs so much for the limited things it can do. An ST-E2 costs about as half much as a whole 580EX II, with "less than half the functionality."
OK, I have the book in hand now. He lists four reasons for less functionality. First is that the ST-E2 has a shorter range than a 580EX II. Personally, I was surprised at how far it worked when a co-worker carried my 580EX down a hallway, and my ST-E2 fired the 580EX. I will try to remember to pace or measure that distance this evening.
Reason two was flexibility, saying the ST-E2 has none, as it can only fire remote flashes within an 80-degree cone of the lens. Personally, I think I disagree with this one. Back to this in a moment....
Reason three is that it can only control Groups A and B. There is no provision for controlling a Group C.
Reason four is that the ST-E2 cannot be controlled from the camera's LCD screen.
Obviously, reasons three and four apply to more experienced photographers. I have only used one group of flashes. I also have not reached the level of controlling flashes with the camera's LCD.
Back to reason two, and why I disagree, at least partially: the ST-E2 works fine on an OC-E3 cord, which Syl Arena praises highly as a basic piece of equipment. He mentions using such cords throughout his book, with flashguns. I have not read the whole book, yet, but have seen no mention,
thus far, of using an ST-E2 on an OC-E3 or other TTL-capable cord.
As I said before, I am glad I started with a 580EX. (My wife bought it, along with a Canon XTi/400D, pre-owned, from a co-worker.) At first, I was intimidated, and preferred using a 220EX, on an OC-E3 cord, but finally
developed the courage to just use that huge 580EX, an amazingly smart gadget.
