A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
If you can afford one, an interchangeable lens video camera can give you the advantages of a DSLR with better image quality and handling. For families, schools and educators, you could choose between basic camcorders (which are very easy to use), iPads/iPhones or compact still cameras.
