Digital cameras are notoriously difficult to design and get right. Where do you start? Who is the customer? What features do you include on the camera? There are uncountable ways to approach a camera development and design programme.
For example, you can create a spreadsheet listing current and near-future ‘must-have’ specifications and cross them out one-by-one to please the techno-consumer. Or you can specialise and excel in specific areas—a more difficult proposition altogether. For the X-Pro2, Fujifilm chose the latter simply because of their heritage of crafting cameras for particular needs.
