Which is the best 5/6/7 megapixels digital camera in the market right now?

Which one is the best - really depends on what you are looking for in the camera. A camera that may be the best for one person may not turn out to be so good for another. It depends on how you are going to use it - shooting family pics, for travel purposes, etc. To find out what kind of camera will best suit your needs, you may wanna check out the website: http://www.digitalcamera-hq.com/ and then use the reviews at http://www.CNet.com to compare the ones that you like.

Canon and Nikon are the best, and Olympus runs a very close second.

7 megapixels if that's the highest one out there right now. The more megapixels, the better quality the picture will be.

the more megapixles the better. you will get a better more clear more detailed pic. but, the more detail in a pic. the lager the size of the pic. file and the higher the cost of the camera

its a SONY or Canon

you cant put canon or olympus you have to put the model because there some olympus and canon what suck and some good ones, like kodak and every brand have good and bad.
I will love to have the canon power shot S80.

Depends on your buget, but I personally like the german brand Leica. Most Leica camera's are world renown for simplicity of use and quality of parts...and bottom line takes great pictures. Some panasonics also use Leica lens which are some of the best in the market.
