What does entry level SLR digital camera mean?

Whether in reference to a digital SLR or to any other product, "entry level" means "made for those who want that category of product, but who do not want or need the advanced features that command a high price." An "entry level" product is a serviceable "no-frills" model that gets you started in a category for a low price. Entry level is defined by both price and features. Some advanced DSLR units cost $8000 or more. Without intending either to recommend any specific cameras or to condemn any by omission, I will mention, just as examples, that for about $550, shutterbugs can have a no-frills entry level Nikon D40x or, for about $400, an entry level Pentax K1000D Super. Canon, Nikon, Olympus, and Pentax are among the major companies that offer entry level DSLRs.
