Guide to Using Your Sigma Wide Angle Lens
Sigma wide angle lens is a type of third-party lens that you can use with your name brand digital SLR camera, including your Nikon or Canon. But, before you can use your Sigma wide angle lens, you need to know some tricks. You will need a tripod or monopod, digital SLR camera and a Sigma lens.
Using a Wide Angle Lens
A wide angle lens allows you to capture approximately 55 degrees of the widest dimension of your image. Generally, the shorter the focal length, the more that you realize what a wide angle lens can do for you. Basically, a wide angle lens allows you to capture more of the horizontal line of your photograph. For example, if you are taking a picture of a prairie landscape, you will capture more of the grasses the further that you zoom out from the landscape.
Changing out Your Lens
The first thing that you need to do is remove your existing lens. There should be a release button near the base or side of the lens on the camera body. Depress this button and take off the lens. To add your wide angle lens, line up the dots on the lens and the body and then rotate the lens in a clockwise movement to attach the new lens.
Use a Tripod or Monopod
It’s worth it to invest in a tripod or monopod when you purchase your new lens. Larger lens are heavy to hold, increasing the chance that you will not keep the camera steady. A tripod or monopod will help you secure the camera and reduce the instances of blurry pictures.
Using a Wide Angle Lens
Wide angle lenses are perfect for focusing on foreground images while making the background fuzzy. This allows you to emphasize the background and deemphasize the background. While you can do this with telephoto lenses, it’s more difficult since they are designed to focus on far away objects. Usually with a telephoto lens, your foreground image will be blurry while the background is in clear focus. You can also distort the look of the foreground image, making it look larger than it really is.
Taking Panorama Shots
While you can purchase special panoramic cameras or lenses, you can also take panoramic shots with a wide angle lens. These lenses capture more of the scene than standard lenses. You can even take several pictures of the same scene and then splice them together in post production.
Changing the Shutter Speed
Sigma wide angle lenses allow you to set your camera to a slower shutter speed without worrying about creating a blurry picture. For example, if you want to capture a moving object, but still keep it in focus, you can reset your shutter speed; the wide angle lens will ensure that the focal point of the picture is in focus. And, you can set up the image so that only the focal point is in focus while the rest of the picture is blurry.
