I am a newbie to the age of DSLR cameras. I purchased a Canon XSi/450d and it of course came with the kit lens. I also purchased the Canon EF-S55-250mm f/4-5.6 IS lens. I am planning on trying my hand at shooting some fireworks tonight and was wondering if any of you professionals here could tell me which lens would be better to shoot with to get the better shots. I will be approximately 1/2 mile away. The set up is on top of a huge mountain, we will be down in the valley in the city. Also; I do not have a tripod and will be doing hand held shooting. I have done some searching and have found that a ISO of 100 with be the best. And a setting of f/11 would be good as well. Does anyone agree with this and let me know what a good shutter speed would be. Thanks in advance for the help.
