Because of the nature of local warranties, importers of grey sets usually offer their own warranty schemes to compensate for the manufacturers' refusal of service. Grey sets do not differ particularly from official imports. They look and function identically. In the early days of camera sales during the 60s and 70s, when lenses had amber coating, the bargain basements for Japanese equipment were Hong Kong and Singapore, through which goods were channeled to European shop windows bypassing the often substantial levy of the official importers. World-market pricing and the Internet have largely eliminated this. Canon gives their hard-selling DSLR cameras names like "Rebel" in the USA and "EOS xx0/xx00" outside it, aimed at preventing the competitively priced US-merchandise reaching Europe where sales are slower but achieve a higher profit.
