What equipment to bring?

For night shots (or any other time you're using a tripod), a cable release is a great way to reduce camera shake. Nikon's MC-DC2 is the recommended one, although you can probably find several third-party options by searching the web.

If you don't want to spend the money (or if, like me, you leave the cable back in the hotel room), you can use the self timer with a delay of 2 seconds. The short delay allows the camera to stabilize after you press the shutter release. However, this method limits your exposure times to 30 seconds or less. With the cable, you can use Bulb mode and hold the shutter open as long as you want.

 

It's nice for selfies. It's kind of tricky to use for long exposures; you normally are standing behind the camera, not in front of it where the remote sensor is. Try it out before you head to Florida. If you can get it to work comfortably, use it.

 

that's awesome, congratulations! That is THE exact same set I have, except I have a sb700 flash

 

At least for my July trip coming up, I think I'll be paring down my kit - leaving the DSLR home. My tests so far with the new Sony A6000 have been tremendous - what a fast little sucker, excellent resolution, great at high ISO and I've been firing down birds in flight tracking them effortlessly. Should be fun to just stick to the new cam, and I'll bring my 18-55mm kit, 10-18mm ultrawide, 55-210mm zoom with 1.7x converter, 35mm F1.4, 40mm F1.8, and maybe one random manual lens just for fun. On a hot summer trip, it'll be nice to keep the kit size down.

 

I had the d80, then the d300, now the 7100; you are right, the 7100 is a long way from the d80/d90 days!
