Can anyone suggest a good way to get a sharp focus on fireworks? I have a Canon T1i DSLR and would like to shoot video of fireworks displays in my community. When I tried this last year, I could not get anything resembling a sharp focus. I'm a lousy judge of distance so I wasn't sure how far away the fireworks were. They were in a large park and I was in the park but I didn't know how many meters/yards I was from the fireworks and, of course, the fireworks travelled a substantial distance as they exploded.
