What kind of lens is suitable for photographing fireworks?

You need a tripod. The two zoom lenses should be fine, but since the 50 is so small, I would take all 3. Start with the 18-55. Personally, I like firework photos that are wider and show a bit of the area or crowd in the shot as well.

Here are a couple of tips:

It depends on a few things, including how close you are to the display, how much wind there is, how "big" the display is. I'd leave the 50mm home. That locks you in so that you won't be able to adjust for any of the variables.

The shutter speed and so on are amazingly flexible. Almost anything will work, depending what effect you want. A speed of 1/2 or faster will capture what the burst actually looks like. Longer times will give you the blur and trails that some people like.

Check out my shots. Pick the style you like and use the shutter speed shown. As I said, the focal length depends on how close you are. A tripod is mandatory and a cable release is almost as important.

Look these over and see what appeals to you. Copy those settings.

Wow I completely disagree with everything people are saying here.

The best lens out of these is the 50 1.4- you want the widest aperture to allow you to use the highest ISO/shutter speed combination you can manage in dim light. You do not necessarily need a tripod if you have a steady hand, I personally would be fine without one, but sure- it will help. The 18mm will be nice to get wider shots (bear in mind that the 50 will crop to 80 on a cropped sensor body), but the slower aperture will require to use higher isos/slower shutter speeds, resulting in potentially noisier and blurry pictures.

Bear in mind that fireworks are extremely bright- you do NOT want to use slower shutter speeds to capture them, unless you are trying to create a stylized light-graffiti effect. Given how bright they are, you do not NEED slow shutter speeds- shooting fireworks is not at all the same as general low-light photography. Fireworks are bright! You could likely get away with 1/100 sec, 50mm, f/1.4, at iso800 or maybe even iso400, f1.4 will allow plenty of light into the lens. That will freeze your fireworks.

The 18-55 and the 50 are your best choice. At 18mm, you're getting a very nice wide angle. The 50mm, meanwhile, has such a wide aperture that it will come in very useful in the longer exposures to provide much nicer colour saturation.

P.S. Yes. You need a tripod... Catching fireworks requires longer shutter speeds.

I'd take all three, All three are of fundamental importance. Buy a macro coupler and put 70-300mm and 50mm f1.4 on that.

Man, you really need a tripod. You'll be shooting at night and in low light so you'll need that.
