Item number LV34FSigma 3 Years Lens Warranty - Activated when camera/lens is registered on the Sigma website. https://www.sigma-imaging-uk.com/ SIGMA 24mm f/1.4 DG HSM I A (Art) Wide angle Prime Lens Nikon Fit
- This lens is designed to minimize aberrations for images virtually free of streaking and warping
This lens provides excellent performance when photographing a variety of subjects from cityscapes, mountain ranges, and the star-filled night sky to indoor photography with low illumination or scenes that require a smooth bokeh effect. Enjoy the astonishing optical performance of the F1.4 series.
- Art line delivers high-level artistic expression
Designed with a focus on sophisticated optical performance and abundant expressive power, Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the highest standard, along with landscapes, portraits, still-life, close-ups, and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes.
- Flare and ghosting reduction
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. Sigma's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
- Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as "secondary spectrum" may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, Sigma lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD ("F" Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives Sigma lenses superlative image rendition undiminished by residual chromatic aberration.
- Minimized distortion
It is not possible to compensate for distortion that is often observed with wide-angle lenses just by changing the aperture value. Therefore, the lens development stage is vital in ensuring minimized distortion. The Sigma 24mm F1.4 DG HSM Art features an adjusted incidence angle of the light source from the surface of the first lens and aspherical glass elements to optimize the power layout at respective positions. This has helped minimize distortion throughout the entire image.
