Usually I'm a fair weather photographer - my camera stays inside when the weather is bad. But I'm heading to Alaska in 2 weeks and realize that given the weather this time of year, it's going to be wet from time to time. I'm taking my D7000 along with 18-105, 70-300, and 150-500 lenses. The 150-500 will probably stay on the boat most of the time as I don't want to lug it everywhere, but the other two will be with me most days. Can anyone recommend something I can use to keep the setup dry? My bag has a rain cover already and I'm not looking to shoot in downpours, but I need something to protect things in a light drizzle.
