As long as you don't need seriously high-resolution photos, video capture, or machine-gun-fast sports shooting, the Nikon D700 has everything you need in a pro full-frame camera for a reasonable price.
The Canon PowerShot G10 is a solid digital camera for enthusiasts who want something more compact to complement a dSLR, but its performance leaves something to be desired.
Nikon's flagship dSLR packs a full-frame 12-megapixel sensor and is a highly versatile imaging powerhouse that lets photographers create images previously impossible to capture.
Pleasing image quality and a wealth of manual controls make the SLR-styled Nikon Coolpix P5100 a good compact choice but its slow performance disappoints.
If you squeeze more megapixels onto a sensor of a given size, a camera works worse in dim conditions. So what's better, more megapixels or higher sensitivity?
