Photography Equipment: Camera Lenses

The one great feature of investing in DSLR cameras is that you don’t need to own ten different cameras to use in different shots. By simply investing in photography equipment, more specifically lenses, you can shoot in a wide array of scenarios. There is no need to go out and buy a new Nikon camera every few months. Instead, you can buy a Nikon zoom lens or a macro lens and still achieve great photographs.

Before you concern yourself with aperture and shutter speed, you need to figure out the purpose of the lens. What are you using it for? Are you shooting up-close food photography or landscapes? If you like to shoot various types of photography, you might want to consider sticking with a standard lens. For landscapes and cityscapes, you’ll need a wide angle lens. If you need to cover a wider range and depth of field, this is the lens for you. A telephoto lens is the exact opposite. Use this when you need a narrow angle range, like for portraits. Shooting something extremely close-up, like little ladybugs? Then macro lenses are the photography equipment you’ll need.

Now that you’ve purchased the lens you need, its time to understand more about the specs -aperture, shutter speed, and focal length. Aperture refers to how open the lens is. The smaller the aperture number, the wider the lens opening. Shutter speed will determine the exposure to light. These two specs work in conjunction with one another and different sizes allow different amounts of light in. Focal length refers to the diagonal coverage that a lens is capable of. When you see “f/2.8″ on a DSLR camera, this is the ratio of the focal length and the diameter of light let in. Putting all these specs together, a lens with f/2.8 lets in more light than an f/22. However, with a faster lens, you will need less light to work with.

When considering just the focal length for a camera, there are popular lengths depending on the type of lens you choose. A standard lens usually has a 50-55 mm focal length. Anything with a smaller focal length is considered a wide-angle lens. Above 55 mm is considered a telephoto lens. As if your decisions weren’t difficult enough, you also have to factor in if you want a prime lens or a zoom lens. A prime lens only has one focal length and a zoom lens has several, allowing you to zoom in. Both have their pros and cons, but remember with a prime lens, you will have to switch lenses to shoot a variety of focal lengths.

When owning a DSLR camera, there is a lot of photography equipment available to enhance your photographs. Those looking to be professional photographers know that expanding your collection of lenses is practically a necessity. Consider your needs and the type of photography you take to determine which lens is right for you.
