Often when I'm cleaning up around the studio, I wonder to myself why I keep so many older digital cameras. Then I have days like yesterday, and I remember why.
I wanted to shoot a time-lapse movie for a personal project I was working on. Nothing fancy, but time lapse was exactly what I needed. I looked at all of my current cameras that I'm using or testing, and not one had that function built-in. I would have to get some sort of accessory. We're talking about good cameras here: Canon S90, 60D, 5D Mark II, T1i, Olympus E-P1, E-PL1, E-5, E-30, and Sony T200. Not one had time lapse function built-in (that I could find anyway).
There was one exception (other than my iPhone): my trusty Canon G9. It has a time lapse option while in movie mode. I charged its battery, put in a fresh memory card, mounted it on a tripod, and recorded a nifty time-lapse movie that was exactly what I wanted. No post production. No fooling around.
I guess that camera won't be going anywhere, anytime soon...
