My husband is the photographer, he recommended this site as a good resource for all digital cameras.

No matter what Camera you buy, the most important thing to remember when buying any Camera is that the LENS matters most. The industry markets Cameras by MegaPixels and Features, but the Lens is what brings the image into focus to be captured by the Camera. A lot of MegaPixels with a poor lens can only capture poor images.
More expensive cameras often have better lenses (but not always). Often the less expensive model, by the same manufacturer, has the same lens but omit features or offer fewer megapixels to keep the price down. Buy the best Lens you can afford. If your budget is limited, consider giving up MegaPixels or Features to get the better lens.
MegaPixels are equal to how big the image you are capturing can ultimately be. The maximum resolution (quality) of the image and the maximum size of the printed image are controlled by how many MegaPixels you have. Remember, most of us print our photos using 4x6 Photo paper and occasionally on 8.5x11 plain paper.
A 4 MegaPixel Camera limits the maximum print sizes to about 8X12 (4x the size of the typical print size). An 8 MegaPixel Camera offers 100% increase in the number of Pixels (over 4MP), but only provides a 50% increase in image size. Therefore the maximum effective print size is for an 8 MegaPixels is 12x18.
Much larger printed image sizes are possible than those listed above, however the resolution or quality of the image will begin to suffer the larger the printed image is made.
Remember also that we often crop images before printing. Cutting away portions of the image reduces the size of the original image. If you crop away half of the image you just reduced the resolution and the quality of the final print has effectively been reduced.
Oh and he also believes that Canon is the way to go.
