One of the best parts of the X5 is the availability of aperture priority, shutter priority, and manual shooting modes. That's extremely rare in a camera at this price. At the wide end, the apertures are: f3, f3.3, f3.8, f4.6, f5.8, and f7.3; in telephoto you have a choice of f5.2 or f6.6. Shutter speeds go from 1/2,000 second to 30 seconds. What's nice is that the X5 has graphics on the aperture and shutter speed onscreen controls, giving you an idea of what setting to use for a subject (e.g. fireworks at the 30-second shutter speed position).
