Canon EOS D30 to 40D
In late 2003, Elaine Ashton very kindly offered to give me her old Canon EOS D30, because she was upgrading to a 10D. The camera travelled from Finland to Germany by post, then to India with a friend early the next year; and in August, I bought a 50/1.8 lens and took my first digital photographs. (Here's one of them.)
In January 2008, my parents very kindly got me a Canon EOS 40D for my birthday. Amazon shipped it to Chicago, and it travelled to India with a friend in February. We took it with us on a camping trip to the Himalayas at the end of the month (here's one of the first photos), and I've been using it ever since.
