The camera is not for style junkies interested in investing copious amounts of cash on svelte designs. If you compare the A550 with the A590, there’s little change in the way it looks and feels. The A590 has a comfortable L-shaped design that makes one-handed operation easier. The bulk may keep you from carrying it in your pocket, but it does compensate by being lightweight.
A selection of buttons sort of clutters the rear of the A590. The screen is a 2.5-inch LCD capable of displaying 115,000 pixels, while the viewfinder placed right above is optical.
