Beware all this "pixel count" stuff. Generally, its horse-sh*t.
Marketing hype designed to fool teh no0blar.
Image quality depends on the quality of the
image processing software in the camera - not just the pixel count.
Buy a camera with the pixels stated as actual. Avoid interpolated or effective pixels - meaning that the camera takes the image and enlarges it before writing to the card. And, as we all know, you lose quality when you enlarge a digital image.
