"Although digital SLRs have been around since the mid-1990s, when Kodak
produced digital adaptations of high-end Canon and Nikon 35mm SLRs, it is
only since the launch in 2000 of the beautiful but deeply flawed Contax N
Digital, that the market for "consumer" digital SLRs has grown. In that
short time the market has already stratified into distinct sectors, from the
fiercely contested sub-£500 mass-market category, all the way up to the
£2000+ professional cameras such as the Canon EOS 1Ds MkII and Nikon D2X."
