In January 2001, we needed to send a Sony DSR-PD150 on an expedition to the summit of Aconcagua, at over 7,000 metres, the highest mountain in the Andes. We needed protection from the environment but failed to find a suitable protective jacket on the market. The best of which fell short of our needs in terms of both protection and ergonomics, it simply rendered the camera almost unusable when fitted. The only solution was to design and produce our own.
