I like taking pictures. I especially like taking pictures with a
good camera. Nowadays I even have a reasonably good camera, like I
did in the film era. Here's my setup, which is very heavy and
excellent for exercise:
I also have a Canon PowerShot A720 IS, which is a more reasonable package to carry with me into the wilderness. It supports CHDK, which is good. CHDK support and AA-batteries were my two primary criteria when choosing this camera. It's really very good. Do you want to trade an EF 400 mm f/2.8 L IS USM for it? I'll even throw in a 2 GB SD-card.
Here is a wireless remote trigger for my EOS SLRs which I made out of a wireless doorbell. Later I modified it to work with the PowerShot also (with CHDK).
