1. Introduction to Digital Cameras

While salesmen at some other stores will ask you "What is your digital camera budget?" or "How much you want to spend?", we at OpticsPlanet.com always start with "For what purpose are you using the digital camera?" The digital camera industry is constantly advancing, and all major Digital Camera Manufactures are forced to come up with new digital camera models every 4 to 6 months. "How can we make people buy new digital cameras more often?" and "How can we make people spend more on digital cameras or flash memory?" are the questions that camera manufacturers ask themselves everyday. As a camera retailer, we are always happy to sell you the latest and greatest digital cameras or digital camera binoculars, but we also want you to get what you really need by making an educated decision in your digital camera selection. We could write a 500-page book on how to buy a digital camera, but we will try to condense the knowledge to a few pages and give you a few major pointers. We are here to help if you need any additional help!
