Sigma lenses are a favorite among astrophotographers and for good reason. These ultra-wide angle lenses capture panoramas that would just not be possible with a smaller lens. For many astrophotographers, there is one lens that has stood the test of time. And it is the Sigma Art 35mm f/1.4. It's relatively cheap, very sharp, and lightweight (300g). But what do you need to know about this Sigma Art 35mm f/1.4 lens?
SIGMA 35MM F1.4 DG HSM ART-
The Sony E-mount
Sigma 35mm f/1.4 DG HSM Art Lens is a wide-angle prime characterized by its advanced optical design. The combination of one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements helps to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with a full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. Standard wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras, however, it can also be used with APS-C models where it will provide a 52.5mm equivalent focal length. One FLD element and four SLD elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
What is Astrophotography?
Astro photography is a specialized type of photography that is used to capture images of planets, stars, satellites, and space debris. Astro cameras can be used by both amateur photographers and professional astronomers. Astrophotography is an efficient tool for capturing stunning images of celestial bodies that makes other kinds of cameras obsolete.
