With an 18-megapixel APS-C CMOS sensor and a price tag of £1,500 body-only the 7D hits the mark perfectly.

The higher-resolution sensor necessarily has extremely small pixels, which never bodes well for image quality.

Really, though, the Nikon D90's features, performance and value are so immense that it has to be given one of our all-time highest scores.
