Just got this new Olympus E-P3 with the 20mm lumix lens. It's a pretty decent camera for snapshots, albeit little overpriced for what it is. Most importantly, it focuses fast enough that the doggies can't escape! The touch screen focus is really great, you just tap on whatever you want focused on the screen, and it focuses and takes the photo. The 20mm does have nice shallow depth of field as well. The one bad thing is the OLED screen, which must be the worst display I've ever seen for color accuracy.
