This article is worth a separate listing, because the differences between Canon and Nikon could be very important in deciding which system to start building—the body is usually only the start. For entry-level cameras, Greenspun recommends the Nikon N65 or N80 or any low-end Canon body (though the Rebel G doesn't let you shift AF off shutter release)—and the Canon Elan 7 and Nikon N80 for intermediate users. The Canon EOS 1V has the best Canon viewfinder. For overall systems, he recommends Nikon for eyeglass wearers, also for macro and wide-angle lenses, but Canon for long image-stabilized telephoto lenses, perspective correcting shift-tilt lenses and autofocus, especially on high-end bodies. Many user comments add to the discussion.
