The Fallacy of Megapixels

I have reached a new conclusion: It seems as though new point and shoot cameras are not as good as older models. Jimmy Joe and I have been on a hunt for a point and shoot upgrade with higher resolution for video. The camera we have right now is a Sony Cybershot my Dad picked out 4 years ago for me, with 6 MegaPixel photo quality and standard definition video. I have decided it can't be beat by any of the new point and shoots available. We purchased one of the newer Sony Cybershots that goes up to 12.1 MP, purported to be a great camera with HD video. So the video was better than our current camera, but all pictures were grainy- whether in low light, indoors, outdoors, whatever. After some research, it seems this is the problem: the higher MP cameras have so many little sensors (microscopic lenses), one for each individual MP, packed into the whole sensor. Because they have to make room for all these little sensors the normal partitioning walls that separate them are lost. Thus, information spills over into adjacent sensors, creating more noise-- hence the grainy look. This doesn't happen with lower MP cameras because there are fewer sensors for the fewer megapixels, and the partitions remain and are effective. The images we took on the newer model just seemed blurry, blurred edges, and blurred colors. Not blurring from motion, more a grainy blur quality. So we returned it and got our money back. I think we are going to stick with our oldy but goody, with its definitively crisp and clear photos. Conclusion: It appears that more isn't better, and that older point and shoots with lower MP capability have crisper and cleaner photos that newer ones. Any thoughts?

*Note: This does not apply to DSLRs. They have a larger sensor that avoids this problem. They are awesome.

that is very interesting. We have found that a small little camera seems to get the job done and is very clear and takes great pics too. I hope that that one will work out for you.

i have no idea about megapixels, all i know is i thought we bought a nice camera too, and it takes a lot of blurry pictures and makes me mad.

We just bought a new one too. Not way nice only like 100 dollars. But still nicer than our old one.. i thought. Its just like you said, very grainy no matter what time of day. Sometimes it takes good pictures, but not what I thought it would. But i think it is better than the old one I had, and it's pink:-)

Point and Shoots are for people who don't care about pictures. I use it most of the time for documentation purposes, and I LOVE the convenience of it. And I LOVE that they can do Photo and Video, I get frustrated with the quality as well, but since I have the capability and knowledge to take great pics, I am thankful for a small easy to carry camera that does it all, and I am not picky how the picture turns out, it is the times when it is more important that a picture is taken than the quality. You guys take great pics though, so I can see why you are frustrated with the Point and Shoots. Your young, I'm just amazed those little cameras can do so much, I am from the days of film and huge bulky expensive video cameras. (OK we still use huge, expensive, bulky video cameras:). Anyway this is the longest comment I have ever posted. Thanks for the info, now I have an even better excuse for why my pictures suck sometimes:)

Weird! I would have never thought. That seems so ridiculous.
