What You Need To Look For When Looking Into New Camera Lenses

By Jake Zertosky

Anyone who has recently graduated to a camera where they can interchange the camera lenses may be feeling a little overwhelmed. The change from a point and shoot camera to a more professional grade model is so much more than just the price tag. Knowing which lens to use for which shooting condition is one of the things that helps set an experienced photographer and their images apart.

A camera that allows you to interchange lenses is known as a single lens reflex or SLR camera. The light that creates the image forms on either a film plane for a conventional film camera, or a digital sensor for digital SLR cameras. This is how a camera captures an image.

Your first choice of lens should be one with a focal length which can range between thirty five and seventy millimeters. Keep in mind that this measurement is for the standard film based camera and digital cameras may have focal lengths which differ from this measurement.

This is because it has a long enough focal length that you do not get any distortion. It is also short enough that you can shoot in different lighting conditions with less chance that your pictures will be blurry. The longer that an image must be exposed, there is a higher chance that your images will be blurred from the natural movement of your hands. Since this is not what you want for your pictures, you should pick the right focal length for your needs.

The next step that many shutterbugs take is to purchase a lens which allows them to shoot animals, birds or sports. The same principals apply to any of these subject matters. You need speed because athletes and animals tend to move faster than you may believe. You also need the ability to get your shot from a fairly long distance away. A good choice is a lens which has focal lengths of between 150 and 300 mm.

The fact that you can take a picture very quickly with the above length of focus is important when shooting sports or wildlife. There is often a lot of action in these pictures so being able to snap pictures fast is important. However you may find that shooting with this focal length may mean that you do not get a wide view of the terrain around you.

For a wider angle of picture, you may want shorter focal lengths. This are also known as wide angle. You can get really neat effects with a fish eye, which tends to distort the image quite a bit. Fish eyes have a very distinctive look that most experienced photographers can recognize immediately.

Finding the right camera lenses is as much a matter of personal preference as it is the type of shooting you are doing. As time goes on, you will find that your collection will expand and you will love trying new and different focal lengths and shutter speeds in your pictures. Good shooting!
