I use a Canon SD 800 IS.  It ain’t the best but it works for me.  I have a friend in the Miata club, Dr. Ellen Rudoph.  She uses a camera similar to Al’s but she told me that she had used one similar to my Canon and had taken 100,000 shots with it.  She works a lot with National Geographic.  She like Al is very good with her shots.
