Considerations When Selecting a Nikon f-4.5 Camera Lens 80-200mm
Nikon f-4.5 80-200mm lenses offer a wide variety of practical uses for serious photographers. With the focal length, you capture not only close-up shots of people but it also works well for sports and action shots. Comparing the features available on different 80-200mm like those from the Nikkor by Nikon can help you locate an accessory that will enhance your photography.What is the focal length of these units?
These lenses are 80-200mm lenses, meaning the focal length ranges from 80mm to 200mm. Focal length is defined as the distance between the point on the lens where the image is sharply and clearly in focus at the point where light enters the lens and the actual sensor or film which receives and records the image.Are telephoto lenses and zoom lenses the same?
A telephoto lens has a focal length of more than 50mm. They may have a fixed focal length with no range or ability to change the focal length such as one with a fixed focal length of 100mm. A zoom lens has a variable focal length, such as the Nikon 80-200mm lenses. These Nikon lenses are both types of lenses. However, any unit that has a variable focal length is considered a zoom. There are wide-angle zoom lenses that have a variable focal length range that is less than 50mm focal length. Given the flexibility of a variable focal length, many photographers prefer a telephoto zoom lens with a range of 80-200mm for easy adaptation to different distances and situations.How does the aperture affect the bokeh of photos?
Bokeh refers to the quality of the appearance of the out-of-focus background portions of a finished photographic image. For optimal bokeh on photos, particularly portrait images where an artistic background is desired to create a contrast with the subject of the photo, lenses with a greater aperture, such as f-4.5, is desirable. The larger aperture of f-4.5 creates a shallow depth of field in the foreground, which is ideal for portrait images as well as an artistic bokeh effect in the background.Is autofocus or manual better on a zoom lens?
Using the autofocus (AF) feature on a zoom lens can be convenient if you are trying to capture action shots quickly and have either ample storage available for taking a large number of images or a great deal of film if you are using 35mm film, thus creating the likelihood that some of the many photos you shoot will be the quality you desire. However, many photographers prefer manual focus on their zoom lenses because they can verify that the lens is actually zeroing in on the subject of their composition manually rather than using the autofocus on another element in the foreground or background of the subject.Content provided for informational purposes only. eBay is not affiliated with or endorsed by Nikon.
