I leave the Canon 18-55 kit lens on my camera most of the time, since it is lightweight and easy to get in and out of the bag. But, I rarely go anywhere without my bag and the 70-300mm lens, so i really use whatever the situation calls for.
I rarely use my fisheye...although it did come in handy the other day.
