- The AF Nikkor 20mm f/2.8D has a longer maximum focal length that allows users to focus on a small part of the scene and offers a narrower angle of view than shorter focal lengths. A wider aperture supports the sensor to capture more light, preventing blur by activating the faster shutter speed. By providing a shallow depth field, the lens allows users to blur the background to draw all attention to the subject.
- Its shorter minimum focal length lets photographers capture more of the scene in the picture while giving them a wider angle of view than longer focal lengths. The wide aperture supports the sensor to capture more light, helping users avoid blurring and allowing them to use a faster shutter.
- It is a telephoto lens allowing users to zoom in on far-away objects. So, it is the perfect lens for wildlife and street photography.
- The widest angle of view is at the shortest end of the lens, allowing photographers to better fit the scene in the photo (based on APS-C format).
- The narrowest angle of view is at the longest end of the lens, allowing users to fit a small part of the scene into the picture (based on APS-C format).
- Close Range Correction System allows users to get closer to their subject. So, it is particularly ideal for macro photography.
- The Rounded 7-Blade Diaphragm affects the way light passes through the sensor. These rounded blades improve the appearance of out-of-focus scenes, allowing photographers to achieve better and softer-looking bokeh (points of light) in their photos.
