Yup, for the fireworks, if not wrong, it's playing with shutter speed, the shutter speed will be open for long, like 1 second or more I think, depending the effect of firework you want to capture; The problem is the timing and estimating where the fireworks will pop, etc.

What I realise is by increasing ISO, you might increase the brightness of your photo but noise level is increased by alot.

I think need more than 1 second. Usually if u are at an event can roughly know where will pop up.

What if I go for really basic ones like the 270EX II?

Depend on situation. If you need fast shutter speed and the aperture is at maximum or desired aperture, you can't get correct exposure, then you need to resort to ISO; Usually ISO should be the last option.

For the fireworks, it's not really about ISO, it's actually underexpose if I'm not wrong, because you want to capture only the fireworks. Higher exposure, the firework will be too bright. Need SIFU aspire to confirm this.

If u can get the best why dont go for the best?

more than 1 sec? hard to estimate leh..

I think so too bcoz fireworks itself is a light source hence if you increase the ISO, the light source will be too bright. Try to reduce ISO and increase EV

Eg,

This is what happen when you increase the ISO:

thanks. very helpful information.

because auto focus need time to focus?

i check the photo EXIF already about 2.5 sec or 3 sec

damm u agito.just now ask for camera lenses dun 1 answer me...now post at fb.

Yea so need to disable auto focus .

what?! that is you slow poke la....people post that one....i share only....

hangy2k post one la.

Not only need time to focus. It might not focus on the fireworks bcoz the background is pitch black and a light comes out suddenly.

the different that seperate the "REAL" sifuness is HOW FAST u able to lock down all those preferences whenever u in ANY situations... if set slow slow ANYONE also can be sifu with some study on optic theory...

btw,that 1 rubbish lens la..we can edit after shoot.what i want is optical zoom.
