When hiking or just shooting for fun or travel, I found this combination way to heavy and unwieldily so I decided to switch to using a much smaller and lighter Nikon D40 with AFS 18-200 f3.5-5.6 lens and Nikon SB600 flash. Using one "do it all" lens is much easier, since changing lenses in the winter or on water could be disastrous. This combo also makes me more likely to just throw the camera in the car, around my neck, or in a backpack, resulting in many more images.
Well, that all seemed like a great idea until I tipped over in kayak with my D40 and lens. While I eventually dried them out and they now work I decided on another rout, a small mirror less retro rangefinder. The Fuji X10 proved to be just the ticket and it easily fits int a baggy when on the water. It is also less conspicuous making it great for city "street" photography. I now use this camera for most of my travel and city photos and so far have been very impressed with the results.
