The Henry Ford Museum/Greenfield Village has a series of fireworks displays for the July 4th "season". I normally use a D750 or D810 and a 24-70 f/2.8 E VR for the purpose. I recently bought a used Z-5 as an intro to mirrorless. For this image, I used the Z-5, FTZ, and a 50mm f/1.8 G, since I was fairly close. I set the camera @ ISO 400, f/13, and a bulb timing. This image was toward the end of the show, and the smoke from the previous bursts was really highlighted by the red shell.
