This Canon powershot sd550 camera is a tough little cookie, especially the viewfinder when you apply pressure to it.

An easy to carry camera as it is relatively smaller than many other cameras on the market it's form and size factors are a big plus.

Another really cool feature is the way the screen tilts the picture automatically for you when you rotate the camera for landscape vs portrait shot -excellent conception. Overall, Canon did a really great job on the sd550, although it feels small yet solidly built and yet has enough weight to it to do the job. A good tip is to get a second battery so you can swap when needed.
