Hey photographers, what's the better camera?

I would choose the Nikon, as Nikon cameras are extremely high quality, and the image quality that you'll get from a Nikon will beat out the Pentax any day, and this is for two reasons. One: Coolpix cameras get Nikkor lenses, and there are no lenses better than Nikkor lenses. Two: Nikon uses a large CCD which will give you a higher quality picture at higher ISO values, meaning that you'll get less noise in pictures taken in low-light.
