Sigma 30mm f/1.4 DC DN Contemporary Lens For Nikon Z-Mount

Advanced Lens Technology

Advanced lens technology refers to the various features and design elements that are incorporated into a lens in order to improve its performance and image quality. This can include things like aspherical elements, low-dispersion elements, and multi-coating. Aspherical elements are specially shaped lens elements that help to reduce spherical aberration and improve image sharpness. Low dispersion elements help to reduce chromatic aberrations and improve color accuracy. Multi-coating is a special type of lens coating that helps to reduce flare and ghosting and also improves light transmission. Additionally, advanced lens technology can also include advanced autofocus systems and lens stabilization for improved focusing and image stabilization. All these elements together help to create a lens that can produce high-quality images with minimal distortion, accurate colors, and sharp details.

Super Multi-Layer Coating

The Sigma 30mm f/1.4 Contemporary Lens is a type of lens that is used to reduce the amount of flare and ghosting in an image. Flare and ghosting are caused by light reflecting off the surfaces of the lens elements, which can create unwanted artifacts in an image. SMC is a highly advanced type of coating that uses multiple layers of coatings on the lens elements to reduce these effects. The coatings are applied in a specific pattern to minimize light reflections and optimize the transmission of light through the lens. The coating is also durable and can help to protect the lens elements from scratches and other types of damage. The use of SMC allows for a high level of image quality and color accuracy, with reduced lens flare and ghosting, which results in better contrast and sharper images even in challenging lighting conditions.

Fast f/1.4 aperture

The Sigma 30mm f/1.4 DC DN Contemporary lens is equipped with a fast f/1.4 aperture, which is a feature that allows a lot of light to enter the camera. The aperture is the opening in a lens that controls the amount of light that enters the camera, and it is measured in f-stops. An f/1.4 aperture is considered fast because it allows a significant amount of light to enter the camera, making it ideal for low-light photography, such as in dimly lit environments or at night.
