According to this test it looks ok compared to the competition:

Personally I'm not a fan of these extreme zooms. My view is that the more you zoom the more the image shakes, which doesn't matter if shooting with a tripod, but if shooting handheld then such zoom is only conditionally usable, plus the aperture closes a lot. In other words 24x zoom on a compact without tripod only works when the sun is shining

Also with big zoom you often have limitations in the atmosphere itself because it's often hazy etc. And people often buy big zooms and then zoom instead of taking a few steps closer to the subject. Pictures (portraits) are much more natural if shot at focal length around 50mm - such perspective as you'd actually see with your own eye.
Just food for thought. If you're photographing eagles on a tree on the neighboring hill on sunny days, 24x zoom will definitely come in handy.
