Superzoom camera with 4 megapixel sensor, 35-420mm optics, plus 3x digital zoom. The lens is f2.8 through the entire zoom range and it is stabilized (I can often take perfectly steady pictures at 35mm, with an exposure of 1/5th sec.). I use this camera mainly for wildlife shots and for special effects on landscape.
The equipment is integrated with additional lenses (wide angle and tele), a professional external flash , flash bracket, tripod, polarizer filter, neutral density graduated filter and a series of step rings which let me to use all the lenses and filters on either Olympus or Canon (but not Panasonic).
A portable CD recorder, stand alone (no PC required) lets me to burn the CDs on place (it accepts the memory cards directly and burns the CD with a single button press), giving me a virtually unlimited picture capacity. Just to be safe, an additional backup of the pictures is made each time on a portable hard drive, accepting memory cards (no PC required).
On this particular trip, I've also used a small Sony Vaio notebook, to work on the pictures during the long oceanic crossings.
