Tamron 35-150mm f/2.8-4 Di VC OSD Lens for Nikon

A flexible zoom lensZOOM LENSAllows a camera to, unlike a fixed-focal length or prime lens, change smoothly from a long shot to a close-up or vice versa by varying the focal length. A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Due to more moving parts, zoom lenses often produce images of slightly lesser quality than their prime lens counterparts. However due to the inherent flexibility of being able to vary the focal length, they are extremely popular for photography where composition needs to be adapted quickly - such as at weddings, for example. with a bright apertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur.

Spanning a unique wide-angle to medium telephotoTELEPHOTOA lens with long focal length capable of making distant objects appear nearer thus larger. Essentially, it isolates and magnifies the subject so that it appears as a full image when shooting from a distance. Telephoto lenses are ideal for photographing subjects that are further away, such as wildlife and sports photography. range, the Nikon F-mount 35-150mm f/2.8-4 Di VC OSD from Tamron is a flexible zoom characterised by its bright f/2.8-4 maximum aperture range and relatively compact, lightweight design for general use. The optical design employs both low dispersion glass and aspherical elements, which help to reduce chromatic and spherical aberrations throughout the zoom range for improved clarity and sharpness. Complementing the optics, an Optimised Silent Drive AF motor realises near-silent, fast focusing performance while a Vibration Compensation system minimizes the appearance of camera shake for sharper handheld shooting.
