Sigma 135mm F1.8 DG AF HSM Fine art - 135mm prime lens

The Sigma 135mm f/one.8 DG AF HSM Art lens with Canon EF, Sony E, Nikon F and Sigma mounts is a member of Sigma's Art family unit characterized by its advanced optical construction and robust pattern. The combination of depression-dispersion FLD and SLD elements helps to reduce chromatic aberrations, while a pair of aspherical elements, i of which is at the rear of the lens, further minimizes distortion and aberration. The optical pattern of xiii elements in 10 groups delivers consistent peripheral brightness and sharpness, even at a maximum discontinuity of f/1.8. A Super Multi blanket has been applied to the lens elements to reduce flare and ghosting.

It has an efficient hypersonic motor that is fast, smooth and repose. Ix rounded diaphragm blades contribute to a pleasing out-of-focus quality with shallow depth of field.

Sigma's Art family lens 135mm f/ane.8 DG HSM, this lens provides a strong perspective compression effect, while its big bore with F1.8 effulgence provides a stunning bokeh effect, minimising axial chromatic aberration, making this effect not simply impressive, but too cute, while providing superb contrast and image quality in every shot. By incorporating the latest innovations in design and optical drinking glass and rethinking every aspect of the lens, SIGMA has ensured infrequent image quality right to the edge of the paradigm, setting the new standard in 135mm telephoto lenses.

In addition to optimised power distribution, this lens features two SLD (Super Low Dispersion) and 2 FLD ("F Low Dispersion") elements. These technologies help minimise chromatic aberrations, which tend to appear in the out-of-focus bokeh expanse in portraits, as well as on thin objects such as branches. The terminate consequence is extreme resolution and clarity throughout the paradigm, even at the widest aperture.

To deliver the loftier resolution capable of bringing out the best in DSLRs of 50 megapixels or more, the focusing mechanism features SIGMA's floating organisation. No matter what the distance from the subject, this lens delivers superior operation from the heart to the edges of the epitome. By also minimising distortion, the lens delivers impeccable image quality, without the need for digital adjustment during epitome processing.

The 135mm focal length offers a surprisingly compressive effect: even at close range to the subject, the telephoto ring allows a variety of dramatic perspectives to be established, and the large diameter with F1.viii brightness makes possible a full-length shot with impressive background bokeh. In short, this lens gives the lensman a full range of compositional options.

Near chromatic aberration can be eliminated past combining a high-refractive convex element with a low-refractive concave element, however, residual chromatic aberration known equally "secondary spectrum" may remain. To minimise this secondary spectrum, which can be a serious problem in conventional lenses, this lens offers up to three types of exclusive low dispersion glass that offering superior functioning: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD ("F" Depression Dispersion). In particular, FLD elements offering ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. The meticulous deployment of these unique types of low dispersion glass and the optimisation of the energy distribution provides peak epitome reproduction without being macerated past balance chromatic aberration.

For optimum optical performance and satisfactory ease of utilise, this lens incorporates the latest applied science, including a large hypersonic motor (HSM), dust- and splash-proof construction and other high-end features. The Hypersonic Hyper Sonic Motor (HSM) delivers ample torque to the focusing grouping for exceptional speed, ensuring uncommonly stable performance fifty-fifty at low speeds. Together with the optimised AF algorithm, this role offers the ability to shoot with fast autofocus. In addition, the focus limiter makes AF very accurate at a distance from the subject for fifty-fifty more active performance.

The Total-fourth dimension manual focus role allows the lens to switch to manual focus past merely turning the focus ring, although this may vary depending on the mountain type. The Nikon camera version of this lens includes the electromagnetic diaphragm mechanism capable of receiving the appropriate signals from the camera body. This feature ensures precise aperture control and stable automatic exposure (AE) performance during continuous shooting.
