The Hasselblad H3D has 39mp for a mere $33,000.00.

Mamiya offers a 22mp back for their ZD camera.

The Canon EOS-1Ds Mark III is a 21.1mp full-frame DSLR.

No, it's far more than 7.

But it depends upon a few factors.
1) the physical size of the sensor itself
2) the quality of the lens
3) electrical interference
4) cost.

These days, point and shoots top out at around 12 megapixels.

Currently, digital SLRs can go as high as 22 megapixels, like in the Canon 1Ds, mark III digital SLR.

And there are even larger sensors used in other cameras like the Mamiya ZD.

That said, above a certain point, you get diminishing returns. For normal print sizes, like 8 x 10 and smaller, a 6 megapixel point and shoot is plenty of camera. If you start cramming more sensor sites, called photosites, onto a sensor, you get issues where the sites are too small to pick up light effectively, resulting in poor performance in dim light and noise from electrical interference. Moreover, cramming sensors into a tiny area means that when light interacts with the lens opening (called an "aperture"), you get optical phenomenon known as diffraction, which perversely makes the picture more blurry as you close the aperture down.

Thus, there is a "happy medium" or optimal number of megapixels for a given physical sensor size, beyond which you get diminishing returns. For most point and shoots, 7 or 8 megapixels is plenty, even if you can buy cameras with 10 or 12 megapixels.

For digital point and shoot cameras, the most mega pixels a person needs is 8. 5 is good, 6 is even better, and 8 should be the ceiling. Anymore, and not only do you not need them, such as 10 or 12, but they also cause the image quality to drop down dramatically. More mega pixels=worse images.

For digital SLRs, the sky's the limits! 10, 12, 16, 21, there's even a 39 mega pixel Hassleblad for more than $30,000! With 39 mega pixels, you could easily print something the size of a 3 story house, and even a lot larger.

Hope this helped.

In theory, there is no limit. It just depends on how densely packed the CCD is, along with its size. Right now AFAIK the largest CCD out there is a Hasseblad back at around 40 megapixels -- it's huge. But there is no reason someone couldn't make a 4x5 back or even an 8x10 back at 200 megapixels. In a few years, who knows?

12mp is the highest for point and shoot

there is no reason that you would need 12

it takes the camera longer to process between shots

not 100% sure but i know there's more than 7 the most i have heard of is like 14 but that was this summer they prob. have more now
