When shopping for a Digital SLR Camera people often overlook or skimp on the camera’s lenses.

Focal Length. Lenses can be classified into subgroups like prime, macro, wide angle, normal, telephoto, and zoom lenses.

Prime Lenses:

Prime lenses are fixed focal length lenses like a 50mm 1.4f lens. Traditionally prime lenses are sharper and faster then zoom lenses.

Macro Lenses:

Examples of macro lenses are 50mm and 100mm macros.

Wide-angle Lenses:

Wide-angle lenses are your broad stroke brushes; these types of lenses have short focal lengths. With high quality wide angles lenses like Canon L series lenses address this convergence issue well. Examples of wide-angle lenses are 15MM, 17mm, 24mm and 28mm lenses.

Normal Lenses:

If you buy just one lens try and buy the fastest normal lenses you can like a 50mm 1.4f lenses. Some examples of normal lenses are 35mm; 50mm, 65mm and some consider a 80mm a normal lens.

Telephoto Lenses:

Lenses with long focal lengths 100mm and higher are called telephoto lenses.

Zoom Lenses:

In my bag I carry a 17mm to 35mm my wide-angle broad brush, 24mm to 70mm my medium brush, and a 80mm to 200mm my short brush. Zoom lenses can give you flexibility and versatility all in one lenses.

You Can Afford A New Lens For Your DSLR Camera

Executive Summary about Digital SLR Camera Lens by Charlie Chalk

You’ve bought your Canon Digital Rebel XT, or your Nikon D80 and it’s come with a nice kit lens.

Aside from Nikon and Canon’s own excellent range of lenses an equally high quality but crucially less expensive group are those from the third party manufacturers.

As both Canon and Nikon have a huge back catalogue of theirs and third party manufacturers lenses from the 35mm Film SLR days that STILL FIT the DSLR cameras of today YOU have a massive selection of second hand lenses to choose from.

Take no notice of the new range of ’specially manufactured for Digital SLR cameras’ lenses that Nikon, Canon and the other manufacturers produce and go to the older film SLR sections.

Camera lenses, especially those that are a step up from the entry level ones, are built to last. So before you loose interest in your new toy because the Digital Rebels kit lens just isn’t cutting it, or your Nikon D80’s kit lens doesn’t give you a better picture than your old point and shoot take a look round the second hand stores, the auction sites or the classifieds and see if you can pick up a bargain piece of glass!

How to Buy Digital Camera Lenses

Choosing a Suitable Focal Length

Keep in mind that the performance of lenses can differ from camera to camera, with the magnification power behind a lens generally being greater on a digital camera than on a 35mm film-based camera.

When you hear about fast and slow lenses, reference is being made to a lens’s maximum aperture, which is the maximum amount of light that a lens can let in. Maximum apertures are measured in f/stop numbers, which are actually a ratio of the size of the lens aperture and focal length.

The Ins and Outs of a Zoom Lens

Unlike a fixed-focal-length lens, a zoom lens often gives you the diversity of a range of focal lengths all rolled into a single adjustable lens.

Add-on Lenses

If your lens utilizes aspheric lens elements, then you can rest happily with the knowledge that your lens will help produce sharper photographs and help keep lens weight to a minimum.

Lenses using internal and automatic focusing also keep lens weight down thanks to less moving parts, and of course allow for faster focusing.

Tips for Purchasing a Digital Camera Lens

Executive Summary about Digital Camera Lens by David Peterson

Make sure you buy a good camera lens when purchasing a camera. Buy a good camera as well, but don’t neglect a good camera lens.

Why? The lens is what your camera sees all your shots through. With most compact digital cameras, you can’t change the lens. Avoid a plastic digital camera lens because it doesn’t have the clarity of a glass lens.

What model of lens?

Ensure you purchase a lens that works with your camera too. A Nikon camera lens usually won’t work well with a Canon camera.

Types of Camera Lens

The most common lenses are: Wide Angle, Normal and Telephoto. The type of lens is determined by the Focal Length of the lens. Lens Focal Length 20mm to 35mm

Zoom; A Zoom lens can change it’s focal length to zoom in. So using a film 35mm lens on a digital camera has an effective focal length of 56mm.

A 35mm lens which gives a medium wide angle on a film camera acts as a traditional lens on a digital camera

Lens Speed

The ’speed’ of a digital camera lens also defines a lens. More expensive lenses have more advanced features.

Try to find a digital camera lens with this feature.

A badly composed picture won’t look great with a great camera lens.
