Nikon 20-35mm Focal Camera Lenses

A Brief Overview of Nikon's 20-35mm Focal Lenses

Nikon manufactures a variety of top quality wide-angle lenses for its full-frame DSLR cameras. Its Nikkor 20-35mm focal length lenses allow you to shoot star landscapes and astrophotography. Capture the night sky, large constellations, or the Milky Way with the Nikon 20-35mm lens, available for various prices on eBay.

Nikkor is the proprietary brand name for all of Nikon's lenses. Nikon's 20-35mm lens was Nikon's first-generation professional ultra-wide zoom lens. Nikon's older DSLR lenses come with a switch that must be turned to manually turn the focusing ring and assume manual focus. The lens has a marking of 20 and 35 on the lens indicating the focal length indices for infrared.

The Nikkor 20-35mm lens comes with a CL-46 hard case and an optional HB-8 flocked plastic hood. Other features include the following (see the manufacturer site for details):

• Size: The 20-35mm lens measures 3.7 inches long by 3.2 inches wide (94 by 82mm).
• Weight: It weighs 22.6 oz (640g).
• Filter thread: The lens has a thread of 77mm.
• Diaphragm: Its diaphragm consists of nine conventional (straight) blades and stops down to f/22.
• Close focus: The lens can focus starting at a distance of 2.7 feet (0.5m).

The Nikon 20-35mm lens works with a conventional rotating polarizer or a rotating screw-in graduated ND (neutral density) filter. Filters used alone work without any issues. If you decide to use two filters together, they can only be used with a 24-35mm focal length. If you use two filters at 20mm, the image will be vignetted at each aperture. The focal length works on film and digital cameras.

• Long exposure: An ultra wide-angle lens can be used to help accentuate the background. When used with a polarizer filter, the lens can stay open longer to create a soft background.
• Depth of field: A wide lens enhances the distance between the subject and background. The focused section will remain sharp from the foreground all the way into the designated distance.
• Distorted effects: The ultra wide-angle lens allows you to create fun warped images when subjects are shot at close-up range.
• Architecture: The lines converge when the camera is turned vertically, creating interesting architecture.
• Star trails: Long exposures at night capture the bright stars in circular motion.
