Nikon AF-S DX Nikkor 35mm 1:1,8G Lens

35mm wide aperture lens with high-quality optics and compact dimensions designed for use with Nikon DX format cameras. Features a large maximum aperture of f/1.8 that offers a bright viewfinder image and is ideal for low light shooting situations. Delivers high resolution and contrast with quiet autofocus operation.

Choosing a suitable lens - some considerations

When it comes to choosing photographic equipment, perhaps the most important decision a photographer faces is which lens system to use. The information below will give you a better idea of which lenses are most suitable for you.

Picture angle

The picture angle relates to the visual or picture range of the lens, whereby different picture angles can influence the perception through the lens. In principle, the focal length determines the picture angle; the shorter the focal length, the wider the picture angle and the smaller the picture. A longer focal length means a narrower picture angle and a larger picture. A normal lens 50mm is referred to as "normal" because its picture angle matches that of the human eye. For greater wide angle coverage, these lenses are favourites of landscape photographers and others who need to shoot expansive scenes. Telephoto zooms in far away objects and scenes and has a more narrow picture angle which creates dramatic close-ups for many different kinds of photography.

Perspective

Perspective describes a phenomenon that can better be described by an example. It is fully determined by the distance between camera and object (see photo further above) In short, perspective is the relative size depth of the object in a picture, will say the distance between foreground and background. When the objects in the foreground look much taller than those in the background, which is often the case when using wide angle lenses, the perspective is altered. Understanding different perspectives created by different lenses helps to choose the right lens for your desired photographical effect.

Maximum Aperture (luminous intensity)

The maximum aperture of an object can determine in which light settings pictures can be taken. Aperture is expressed by the f-stop number in different forms. For example, f/8, F8 and 1:8 refer to the same aperture. Lenses with maximum aperture (low f-stop number) are light intense objects, enabling faster shutter speeds. This means tripods and flash units are needed less and it is possible to control depth of focus (see below). The object appears brighter through the lens which makes focusing easier. Lenses with lower maximum aperture (higher f-stop numbers) enable slower shutter speed and are furthermore lighter and more compact than more light intense lenses. At Nikon you can choose from a variety of Nikkor lenses with the same focal lengths but different maximum aperture.

Depth of focus

The term refers to the areas on the photo, in front as well as behind the main image, that are depicted sufficiently clear. Depth of focus can be adjusted by changes in the aperture diaphragm. The smaller the aperture diaphragm, the higher the depth of focus. This means picture with larger apertures like 1:1.8 show a blurry background, while using a smaller aperture like 1:16 or 1:22 deliver pictures that are mostly focused. Focal length is also of importance as depth of focus decreases by increasing focal length of a lens. Wide-angle lenses achieve more depth of focus at all focal lengths than telephoto.
