No offence intended to you, my friend, but perhaps one should try and better understand his/her equipment. Equipment, however reliable, is still prone to failure, or technical hiccups. Knowing one's equipment thoroughly will help one to troubleshoot in the event of a failure or problematic behaviour.
It's like your IA drills.

We are discussing on purely the loose empirical discussion of the difference in pictures taken with flash from diff cameras and their possble underlying reasons and solutions. We are not discussing the thread owners attitude towards his equipments. Of cos everyone shld know everyone's equipment. The thread owner prob know what to know for himself. So lets sidestep such rhetorics and return to the topic at hand.

Well that is what we are here to discuss about.
This forum is very useful for sharing information and objective opinions that we cannot find on review websites and books.
I have learned so much in the last 12 hours about my flash system.
Rather than take a person's comments literally, I prefer to open the discussion so that seasoned users can share their knowledge and experience to us. Lets be objective and not pass judgement on anyone.
A suggestion is only as useful as an open mind.

Chances are, the 2 cameras meter the scene differently and thus send different information to the flash for it to decide on the flash power. Having said that, because of the inverse square law, it is impossible to light the background as evenly as the foreground given a typical banquet hall condition... unless the background is lit by other means (exiting light sources or flashguns aimed at lighting the background); regardless of what system or flash that is used, given that both flashes are fired off in a similar position and angle.
Why not ask the same friend who shot using his Nikon to shoot using your Canon?
I would say metering methods have a great part to play. Because of how the camera reads the scene, then communicates to the flash, and how both the camera and flash work individually, and together as a unit, you may get variable results.
Your friend might be on a mode called TTL-BL on his Nikon Speedlight. This means the flash will read exposure settings and try to fill in with the flash such that your result is more balanced with the ambient light. :dunno:
With so many factors at play, I think thats why some working photog who depends heavily on flash sometimes turn to Nikon, as it give more conisistent results "out-of-the-box", as compared to some other system that may need more tweaking. Hmm, shall we post this in Nikon forum and invite some discussion and flak?
:bsmilie:
de-stan, start a thread there leh, we will bring some extinguisher when u "catch fire". jokes aside I think some Nikonians can shed some insights and findings with us

Maybe. But they do meter differently. 40D doesn't heavily prioritize the active AF point as 10D. Also 40D is a bit more conservative.
de_stan: I tried to help but apparently you're not so interested in solving the problem and keep going back to the brand X vs. brand Y thing. :dunno: Good luck with your photographs.
hey,, I have try.. No problem at all.. it the Photographer .. not your equipment
I do feel the same about Canon Flash...
I can shoot 2 shots at the same scene and settings and come up with 2 different exposures/image
It is frustrating at times... that's why i long for a new canon cam with good enough ISO performace so that I will never ever have to use the canon flash in low light (ball room / indoors etc)
To cap it off... the locking mechanism of the 580mk2 is definitely not top notch...
out of nowhere.. the flash will stop triggering for no good reason
this is true, at least for the 4 copies I have used before
when it happens to 4 copies bought seperately and on different cameras... u start to stress if the darn flash is gonna fail you at a critical moment which is quite stressful
On a sidenote.. anyone selling 580mk1?! hahahaha

Hi i usually use this technique when the background is much brighter and the subjuect become a silioutte ...I sometime have this problem to with the back ground to dark which i dun really like . Is it a common techniquue u use to have a more balance lighting ....think i can use this duirng event :think:
As a nikon user myself ie sb600 there is a function BL TTL which will balance the background light and forground ..sometime work sometime dun i.e maybe i dun really know how to used it :embrass:

I find that I can get consistent result using 580EX and my 20D. It's a matter of practice, experience, and figuring out what the camera / flash combo will do under certain situations. I'd offer some suggestions, but the OP declined to post images so we're reduced to debating about differences in flash systems.
Oh my, tats bad. Sorry to hear that. To the contrary, i LOVE the locking mechanism, its fast and reasonably secure (not that i go cliff-hanging and Iraq field photog, :bsmilie
Yes, the flash did stop on me several times. Had to switch off and on the cam and the flash again. And I thot I was alone!
you arent the only one,, many infact regretted buying 580II

Can I speculate?
Canon 580Mk3 will be announced tomorrow! :bsmilie::bsmilie::bsmilie: Just joking.
Would certainly like to grab hold of a nikon system to test out
