The grey market for photographic equipment and other such electronics is thriving in heavily taxed states like Singapore with dealers importing directly from lower taxed states and selling at lower prices, creating competition against local distributors recognised by the products' manufacturers. "Grey sets", as colloquially called, are often comparable to products purchased from the manufacturer's preferred retailer. Lenses or flash units of parallel imports often only differ by the warranty provided, and since the grey sets were manufactured for another state, photographic equipment manufacturers often offer local warranty, instead of international warranty, which will render grey sets ineligible for warranty claims with the manufacturer.
