If you are looking for a database of digital cameras specifications in Excel format to create a website, use in a repair shop or anything similar, I created an Excel database for you. Contains 36 camera brands with a total of over 3700 models.
I created another mobile phones database with only models currently sold in Indian market. Due to poor sales I no longer update this database and you are advised to buy worldwide phone database.
