One good thing about a digital SLR camera is its capability to allow its user to be creative without any restrictions. Having an interchangeable digital SLR lens is one such capability.
Of course some can argue and say that compact digicams also offer adjustable lenses to suite your need but it all boils down to speed. An attached lens on a compact digital camera is driven by a motto, which may not react as fast as you can when you adjust an interchangeable lens in a DSLR to get a quick shot.
If you insist on using a high compact digital camera with a built in lens then we suggest you use an auxiliary macro lens that slips into your built in lens using an adapter. This way you can attain better picture quality for macro photography.
A digital SLR lens enables the photographer to use a different lens for each specific shot. For example a landscape shot requires a different landscape digital SLR lens than a portrait one so it can cover a wider angle. In the same way a separate digital camera lens is needed to take clear shots of insects and needles on the floor to a full size image of a skyscraper, action, low-light, and wildlife.
Finding the right digital SLR lens is as hard as finding a digital SLR camera itself. This is mostly because there are so many lenses that are being sold these days and you can never be too sure which one will work well for you and your digital SLR. They come in different prices and sizes, built for all types of professional and non professional cameras.
Interchangeable lenses for DSLRs are built to fit with a specific lens mount. A lens mount is what connects the lens and the camera and allows for a free flow of electrical impulses or signals between the two. Often it is advisable to use a DSLR lens that is built by the same manufacturer as the DSLR camera, for example use a Nikon lens on a Nikon body. There are, however independent lens manufacturers such as Tokina, Vivitar and many others.
When you buy a digital SLR lens, you should not be just taken by the price because there are so many others factors that determines the price of a lens. For example you may need to buy a digital SLR lens that has a certain maximum aperture and focal length. So this is why you are most likely to find a wide range of prices on lenses. It must be obvious to any one that the more expensive the lens is the better it will be at taking great photos. If it is expensive it means someone took his time to make it such that it understands the surroundings i.e. the distortion due to light and color and can produce but do be careful of being robbed.
