    i have a feeling this whole "LCD Screen" phenomenon is going to take a bit of a learning curve.

    my other flash is a 420ex, which is pretty much as auto as auto gets.

    i assume i can adjust the power output of this flash, but what other kinds of cool shit can i do?

    i really like the one-button swivel/rotate. seems like a much more 'stout' flash.

    Manual output, zoom head, 58m guide number instead of 42m, weather resistant if its an EXII, stroboscopic flash, and the ability to function as a commander.

    I dont know much about the 420. Honestly, I dont know much about anything thats not the 580EX II as thats the one that I have. :hs:

    yeah, i knew the 420 did ettl and had a zoom/rotate/tilt head ... that's about it.

    what's a "GN"? :o

    wirless triggers should be here by next week, 40D shows up tomorrow. can't f'n wait.

    You dont know what the naming of the speedlites correspond to do you?

    The GN for the 580EX II in meters is 58. Its that way with all Canon Speedlites. Educate yo-self

    Taken from http://www.bobatkins.com/photography/eosfaq/ex_speedlites.html


    Canon Speedlite 580EX

    This is the "top of the line" speedlite. Like the 420EX it has a head that tilts, swivels and zooms. However it's loaded with extra functions. It can act as a wireless controller for wireless flash operation (and it can also act as a slave). It has a variable stroboscopic flash mode (from 1 to 199 flashes/sec at from 1/4 to 1/128 power) and in manual mode the power can be set anywhere from full power to 1/128 power. The zoom head can be manually set. It's smart enough to know the sensor size on DSLRs made after the EOS 300D and adjust the flash zoom setting to allow for smaller sensors (which results in less wasted light). It can tell the DSLR about variations in the color temperature of the light due to charge level and so allow for automatic color balance corrections. There are also 14 user setable custom functions. About the only thing it doesn't do is make coffee. Of course the price of this is reflected in the cost, which is around $380, but if you do a lot of flash work, it's worth it. See the 580EX release notes for more info on the 580EX.


    A stroboscopic flash means that you can set the flash to fire multiple times within a single exposure.

    And ace, l2wikipedia

    The guide number for an electronic flash measures its ability to illuminate the subject to be photographed. A higher guide number indicates a more powerful flash. For example, doubling the guide number means the flash can illuminate an object at twice the distance, or for an object at the same distance can be used at one quarter the film speed. (Doubling the guide number requires a quadrupling of the flash's power - see the inverse-square law).

    you moron, every single flash has a different GN. Ace's GN on his 580 II will be different than mine. :mamoru:

    Actually it wont. The GN changes depending on what setting youre on but Canon sells them by advertising their maximum GN, which in this case is 58m...



    fuckstick.

    Learn something before you try to call me out kplz?

    EDIT: Bolded so that hopefully your stupid ass can make sense of it this time around.

    again, you've obviously never tested a flash for a GN :rofl:

    they give an avg, usually on the high side, but it in no way is a max or min.

    Right. You go with that and Ill go with that Canon techs have told me.

    Whatever the case, even if youre right, its just semantics.

    I could reword my post to say "58m average high side number instead of 42m average high side" but youd still try to argue with it because youll never just admit you were wrong.

    If I was wrong I'd admit it, but I'm not. advertised guide numbers are like advertised gas mileage on a car. its crap and everyone is different. you won't believe ow many flashes are a full stop or more underpowered to their specs but most never know. my old 550 was 2/3 faster than the advertised GN

    Right...So avg MPG is avg MPG.

    If he bought a Prius and wanted to know how it was different from his Veyron, would avg MPG not be a valid point to bring up?

    Whatever the case, the 580 EX is a more powerful flash than the 420 EX. Its a shame that ace's search for information has to be bogged down in this pointless crap.

    whatever man, without testing it theres no way to be sure it is in fact more powerful. I've seen many a bad unit come out of the box.

    and ace, get a Flip It for it, great modifier and decently priced.

    Not just sports. Ill shot anything so long as there is natural light. Ill be the first to admit I know very little about using a flash for photography. I know a lot about it, just not a lot about actually using it.
