MTF CHART

The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens' performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).

The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.

*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Inner focus system

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON' (AUTO).

Exclusive low-dispersion glass

Careful arrangement of exclusive low-dispersion glass elements gives SIGMA lenses superlative image rendition untarnished by residual chromatic aberration.

Super Multi-Layer Coating

SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.

Water and oil repellent coating

Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

Aperture ring

Aperture ring, designed to help users work intuitively.

Aperture ring click switch

Offers a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.

Aperture ring lock switch

A ring lock system to prevent from unintended movement of the aperture ring during shooting.

AFL button

The AFL button can be assigned with various functions widens the range of operations available on the lens.

Focus Mode Switch

Using this switch, it is possible to switch the focus mode between AF and MF.

Focus Limiter

Offers customization for the driving range of autofocus. It makes it possible to limit the drive range from a specific distance to a long distance or a short distance.

Dust and Splash Resistant Structure

This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.

*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
