Tips for Telephoto Lens Photographs
Would you like to emphasize the subject of your photograph? Here’s one solution: use a telephoto lens and get a close-up view.
A close-up photograph of an object, person, or animal gives us perspective and details that we can’t appreciate from far away. A telephoto lens allows you to get optically close to the subject when you can’t get physically close. A telephoto lens brings distant objects closer. Like a telescope or binoculars, the image is closer and larger.
There are two types of telephoto lenses - fixed and zoom. A fixed lens covers one distance. Some common examples are the 135mm lens, 200mm lens, and 400mm lens. Zoom lens will have a variable focal length and will cover a range of distances. Some common examples are 70-200mm and 80-400mm.
There are several advantages to a telephoto lens:
Getting closer. Sometimes a barrier or distance from the subject prevents you from physically moving closer to your subject. In those cases, a telephoto lens works perfectly because it brings the subject closer. While at the pond, I found I couldn’t get any closer to my subject, a dragonfly. My telephoto lens was able to do the trick.
Highlight details. A telephoto lens can focus on a specific detail of your subject. In addition, it can isolate the subject from a distracting background, making the details even more pronounced.
Great portraits. Telephoto lenses work well for head and shoulder portraits, taking sharp photographs without a distracting background.
Natural photographs. A telephoto lens allows you to photograph people in natural surrounding and poses. Being farther from your subject, you can take photographs without your subject noticing. At the beach, I was able to capture this close-up photograph of my daughter from a distance.
When purchasing and using a telephoto lens keep the following in mind:
Use high shutter and film (ISO) speeds. A telephoto lens magnifies the image. As a consequence, the effects of camera movement are magnified as well. High shutter speeds are necessary to get sharp pictures with a telephoto lens. What is a good shutter speed? A good rule of thumb is that the minimum shutter speed should correlate to the camera’s focal length. If you're shooting with the camera's lens zoomed to 300mm, set the shutter speed to 1/300 second or faster. Another option is to increase the camera's film (ISO) speed.
Minimize camera shake. Since camera movement is magnified with a telephoto lens, you need to use fast shutter speeds to avoid camera shake. If you must use a slow shutter speed, use a tripod. Another alternative is using a telephoto lens with image stabilization (IS) or vibration reducing (VR). These mechanical devices inside your lens can detect camera shake and compensate for it.
Maintain precise focus. In most telephoto lenses, the depth of field is limited so focus needs to be precise. To aid in focusing, purchase a camera with automatic focus. A camera’s automatic focus is faster and better than manual focusing.
Take advantage of a wide aperture. When taking photographs with a telephoto lens, you have the option of using a wide aperture (such as f/4) to create an uncluttered background. When you want to really focus in on your subject use those wide apertures to blur the background.
Use a teleconverter. Another popular tool in close-up photography is the teleconverter, often found in 1.4X and 2X lengths. These lenses mount to your camera to make your telephoto lens even longer. For example, a 2X teleconverter would make a 200mm lens, a 400mm lens. Although they give you more versatility with your telephoto lens, they require even higher shutter speeds and extreme care for camera shake.
Next time you want a close-up photograph or you experience a barrier, remember to use a telephoto lens. Take care to use high shutter speeds, minimize camera shake and use precise focusing. Then, you’ll have that photograph that really emphasizes your subject!
