I brought a Canon EOS 40D and the longest, most versatile lens then available for that camera, a Tamron 18-270mm ƒ/3.5-6.3. This outfit gave me the 35mm equivalent of 29-432mm with a stabilized (Tamron calls it Vibration Compensation, or VC), reasonably fast, autofocus lens. Sure, sometimes I wished for more wide-angle when under an architectural masterpiece, and sometimes I wished for more telephoto reach when we saw elusive wildlife, but 99% of the time, that 29-432mm was all I needed. My only accessory was a polarizer for my lens. I also had two extra batteries and a good-sized JOBY GorillaPod tripod. We photographed every day, almost all day, especially when we got to a new place and didn’t need to “move on” till we decided it was time. My equipment held up fine for the entire 21 months.
