Vibration Reduction (VR) is an image stabilization technology that minimizes blur caused by camera shake. Using a VR NIKKOR lens can result in sharp images in low light, under windy conditions or when using a physically large NIKKOR lens, at up to four stops slower (with a VR II lens) than a non-VR lens.
Extra-low Dispersion Glass
Nikon’s Extra-low Dispersion (ED) and Super ED glass help correct chromatic aberrations, or optical color defects, caused when different light wavelengths do not converge at the same point after passing through optical glass.
Macro photography is one of the most interesting types of photography, as it lets you show detail that is otherwise not easily seen by the naked eye.
DX NIKKOR Lenses
Nikon digital SLRs have either an FX or a DX sensor. The FX sensor, measuring 24x36mm, is roughly equivalent to the size of the 35mm film frame. The DX sensor is smaller, measuring 15.8x23.6mm.
Used on Nikon SLRs and NIKKOR lenses from the introduction of the Nikon F in 1959 to current models, the bayonet-type F-Mount is the communication link between Nikon SLRs and NIKKOR lenses.
Zoom Lens Maximum Aperture: Fixed and Variable Apertures
Zoom lenses are beneficial because they allow for a range of different focal lengths without the need to carry multiple prime (fixed focal length) lenses. This lets the photographer quickly zoom in and capture the shot, then zoom back for another at a wider angle. While this is a wonderful advantage to have, there are optical limitations that should be understood when using a zoom lens.
