I've used four cameras actually. I started out by using a Panasonic Lumix ZS5. It is a small point and shoot camera with good video-taking abilities. It doesn't have much zoom but it is a good pocket-sized camera to use for candid snaps. I will continue to use this camera for random pics since it is so reliable and takes sharp images quickly. I do recommend this camera for walks about town and video in a pinch. Examples of photos taken with the Lumix:

Because some of the limitations of the Nikon were becoming increasingly frustrating and I had been considering graduating to a proper SLR camera with interchangeable lenses for some time, after much research into what camera would satisfy my zooming and active wildlife photo-taking needs, I settled on the Canon EOS 7D with the 28-135mm kit lens. For zoom, I bought the Canon 100-400mm f/4.5-5.6 L IS USM lens. I'm still learning how to use the new camera (SLR is a different world than automatic point-and-shoots) but I'm very satisfied with the results so far and will stick with this combo for some time. I used it for the first time last weekend in auto mode and for such a simple setting, it performed exceptionally well. I had to do practically zero post-editing on the images after I downloaded them. I'm excited to see how much I can do with this new combo. Photos from my first outing with the new kit:
