The megapixel thing is a lot of hype. It is not the end all answer to digital photo quality. Here is some interesting reading: (and by the way, I did not have to read this article first to know this, it just lays it out better than I can explain it).

The Nikon D40 kit DSLR is a great camera. 6mp but will likely do all you need, especially just starting out. The D40x has 10mp I believe.





The Canon Rebel digital SLRs are also in the 8 - 10mp range, but cost more than the Nikon.

%26quot;Steve P%26quot; is right, but to answer your question about the difference, the more megapixels, the more detail can be captured.





For images to be displayed on the web, or, even in smaller, prints, it does not matter so much since not much detail can be seen in images this size. The, theoretical, pixels of a seven megapixel image are too small to see, so, you%26#039;d not be able to see the difference between this and a ten meg image on a five by seven inch print.





However, if the image is blown up to a twenty by thirty inch poster, the image with fewer pixels would more easy show each one, since the pixels will be larger than in the same size image with more pixels. And, this may only be true depending on the quality of the printer. If printed on an inkjet plotter, the resolution on those is so, relatively, poor, that the differences may STILL not be all that apparent.





So, unless you plan to blow most of your images up to these larger sizes, the money you may spend to find a camera with a higher meg rating may be wasted.
Reply:an easy way to think about megapixels is the larger the mp rating the larger you can print without distortion. as you expand images they start to distort. this is why some images may look pixelated (all the little noticeable blocks). in film this is called grain. you can only stretch an image so much before it starts to distort. generally speaking it%26#039;s about 1.5 times the original.


as far as buying advice i%26#039;d go for the canon rebel xt (NOT the xti). the xt is an 8mp digital slr. it takes great images and will print out much larger than you will probably need. you can pick the up at b%26amp;h photovideo for about $450 and it comes with a 18-55mm zoom lens.
