When attaching a lens with telephoto (or zoom) capabilities to your DSLR camera, it's a pretty straightforward process. However, because telephoto lenses provide such a different look than standard lenses, you may experience some problems when using them.
Use these tips to troubleshoot use of your telephoto DSLR lenses.
- Certain telephoto lenses will only work with certain DSLR cameras. Before purchasing a telephoto lens, be sure that it is compatible with your model of camera.
- Most telephoto DSLR lenses allow you to choose between autofocus and manual focus. Be sure you know the exact settings you need to use when switching to manual focus. Some cameras allow you to switch to manual focus simply by flipping a switch on the lens; others require multiple steps. Failing to follow the proper steps could result in a damaged lens.
- When cleaning your telephoto DSLR lens, first use a blower brush to remove particles, followed by gently rubbing the lens with a clean, dry cotton cloth or a lens tissue. If you begin rubbing the lens with the cloth or tissue before blowing off any particles, you could scratch the lens.
- With especially large telephoto lenses, it's important that you do not try to carry the camera one-handed. Holding the camera alone or the lens alone could cause damage to the connectors because of the weight they'd be trying to support. Use both hands to support both the camera body and large, heavy lens.
- Large telephoto lenses tend to lead to blurry photos because of camera shake. With a large telephoto lens, try using a tripod to prevent such problems. Many high-end DSLR telephoto lenses include vibration reduction or anti-shake features, which also help with preventing camera shake. If your lens includes this feature, be sure to use it any time you're having problems with blurry photos.
- Finally, when not using your DSLR telephoto lens, be sure to place the protective caps over both the front and back of the lens. Protecting the back is important for protecting the contacts that allow you to attach the lens to the camera. Be sure when storing the lens that you store it in a dry, cool place that isn't subject to direct sunlight.
