The N-Photo experts say…
Take the best ultra-wide zoom lens you can. The 14-24mm f/2.8 is a great lens, but for DX bodies Tokina offers sharp lenses that go ultra-wide, too. The zoom lenses give you room to breathe without having to compose with your feet, so to speak.
If, like Brandon, you only have a day or two to get your shots, you have to be adaptable. Check weather forecasts before heading out and be prepared to switch gears (or even gear) mid-shoot to make the most of what’s happening around you.
Even during the brightest days, stopping down to f/16 and ISO50 can produce underexposed shots, so it’s always worth taking your tripod. Once you have the Nikon steadied, it doesn’t matter how slow you go with the shutter speed.
The Firefall event happens for a few days in February, and there are many other times around the world where optical phenomena occur fleetingly for a days or even a few minutes. Be prepared for competition, though.
