Sony FE 28-70mm f/3.5-5.6 OSS Zoom Lens

The Full-Frame All-Round Performer

A top pick for users looking for a lightweight all-around zoom, the Sony FE 28-70mm f/3.5-5.6 OSS Lens is a great go-to for full-frame E-mount lens shooters. The lens uses a variable f/3.5-5.6 maximum 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. range in order to achieve light weight and compact size and incorporates one extra-low dispersion element and three aspherical elements to minimise aberrations throughout the range. Also, it has a linear motor and internal focus that enable fast, reliable autofocusing. On top of this, the Sony FE 28-70mm f/3.5-5.6 OSS 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. offers built-in Optical SteadyShot image stabilisation to combat the effects of camera shake. Additionally, it is dust and moisture resistant and is equipped with a seven-blade circular diaphragm for smooth bokehBOKEHPronounced: /ˈboʊkɛ/, /ˈboʊkeɪ/ [boh-kay] or /ˈboʊkə/ [boh-kə] Originating from the Japanese word Boke (ボケ), meaning 'blur' or 'haze', it refers to the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. It has also been defined as the way the lens renders out-of-focus points of light. Bokeh depends on various aspects of lens design. Aperture design has the largest effect on Bokeh, and generally a lens with a more rounded aperture produces a more pleasing, natural Bokeh..

Coupled with a Full Frame E-mount camera from Sony, this lens delivers big camera performance in a remarkably compact, easy-to-handle package.

Capture smooth, blur-free images

Built-in Optical SteadyShot image stabilisation within this lens for Sony mirrorless cameras provides smooth, blur-free photos and videos when shooting handheld.

Smooth defocusing

Instead of a standard polygon-shaped lens aperture, the Sony FE 28-70mm f/3.5-5.6 OSS lens features a 7-blade circular aperture for more natural, rounded defocusing, or bokeh.

Refined optical performance

Aspherical lens elements minimise distortion while ED (Extra-low Dispersion) glass elements provide superior contrastCONTRASTThe difference between areas of different brightness levels in a photograph: A high-contrast image has a greater difference between light and dark areas, whereas a low-contrast image has a narrow range of tones. Contrast is used to direct a viewer’s attention to a photographer’s subject either with colour contrast (bold versus duller colours) or tonal contrast (bright versus darker tones). , resolution and colour fidelity.
