[zig]

hi whats the big deal with 580ex? wahts so great about it?
when is it coming out and how much will it cost?
why get that when e-ttl2 can be performed with the big ass 550ex?

[knoxknocks]

hi zig,

sorrie, a bit suaku and a newbie at this...does the 550ex really support eTTL-2? From my understanding, eTTL-2 is a new algorithm developed for 1D and 20D? I was always under the impression that the 580ex is the first model from Canon that provides eTTL-2 support.

Read the manual for both the flashes and do your own comparisons.

The big deal - bigger GN, better design, intelligent chip that adjust flash according to sensor size. Supports ETTL II. Built in diffuser and bounce card

if use 20D, go for 580ex lor, if not, go for 550ex :P

I was hesitating, end up buying 550ex cause i can't wait anymore need to use it soon.

According to canon's specs, ETTL-II works with the 550EX and even the 480EX. It's the body which matters.

480EX? You mean to say 420EX?

"To summarize, there are two important points to keep in mind. First, E-TTL II does not require any changes to either the flash units or lenses used with an E-TTL II camera - the changes are all basically internal to the camera body. And second, while E-TTL II does use distance data when it’s available and when it’s appropriate (eg: when using direct non-bounce flash), it doesn’t prevent you from using older lenses.....

Camera units which support E-TTL II:
EOS 1D mark II, EOS 30V/33V/7S/Elan 7N/Elan 7EN.

Flash units which support E-TTL II:
All EX series Speedlites: 220EX, 380EX, 420EX, 550EX, MR-14EX, MT-24EX."- Flash Photography with Canon EOS Cameras

Either 550EX or 430EX is good enough.

[benny]

430 should be EZ series. 420 is available in EZ and EX right?

[jojo]

How about Sigma EF-500DG super ??

yep same same. Not changing to 20D any time soon, so went for the 550ex too. To my amazement, its really very very much better than a 420ex.

If you still don't know what the big fuss is about, it means you're not big enough to use it! You just don't need it!

Ok, juz a cheky comment... Read the specs and you'll see the differences between the 2. I think the main fuss for most people is the difference in price. Features wise, the 580EX is an improvement over the 550EX. Question is, do you need the extra features and is it worth it to you?

[canturn]

It's about $680 SGD. Frankly, if u don't use the extra features, no biggy.

It's available in HK and B&H. Not in Singapore yet, so unless you want a set w/o warranty
