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 when hiking into the wilderness. It supports CHDK, which is good. AA-batteries and CHDK support 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 with CHDK preinstalled.
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).
I have modified a bunch of cheap Chinese "thumb" video cameras from eBay ("MD80" or "MiniDV" cameras, they were actually very good at the time, for some $20 toys) to fly onboard an amateur rocket, and since then I have repurposed one of those modified cameras for a DIY deep water camera at depths of nearly 50 meters.
Since I bought my 1Ds-II, the 5D has mainly been gathering dust. That also means its batteries have long since died due to disuse. I recently found the AA battery holder that came with the BG-E4 battery grip. It's said to be an "emergency only" fall-back, but as a test I filled it with six Sanyo Eneloop low self-discharge NiMH cells that I've already been using in my flashes for several years. I was able to shoot over 400 test shots with it, and still the batteries would not quit (though by now the battery icon was flashing). This makes me want to put the 5D into use again, as I won't even need to invest in new batteries to do so!
