Best sigma lens for sony12/29/2023 ![]() You can remove it, but if you plan on using a tripod (a requirement for night sky work), you should use the lens mount as the attachment point, not your camera (the lens is front-heavy). Sigma includes a rotating tripod collar with an Arca-Swiss dovetail foot with the lens. It's too big to support front filters, but the lens includes a rear slot for gels. The 14mm is fully weather-sealed, and the front element includes an anti-smudge fluorine coat, so it's ready for outdoor work. The barrel uses a mix of thermally stable composite (a high-grade plastic Sigma says is lighter but just as durable as aluminum) and magnesium in places where metal makes more sense. And, like the 20mm, it includes a manual focus lock and incorporates a heat retainer into its barrel (meaning you can add a lens heater to fight condensation without impacting the frame). The Sigma 14mm F1.4 is just as good at suppressing sagittal coma as the company's 20mm F1.4 lens in the field, for instance. Sony touts the FE 14mm F1.8 GM for astro work and it tests well for that discipline, but Sigma leans further into astro features here. For reference, Sigma's 20mm F1.4 DG DN Art comes in at 3.5 by 4.5 inches, and 1.4 pounds. If you don't mind giving up a half-stop of light, the Sony FE 14mm F1.8 GM is downright small by comparison (3.3 by 3.9 inches, 1.0 pounds). It's a heavy lens to carry, especially if you've got others in your bag. The 14mm F1.4 DG DN Art's 19-element, 15-group optical formula results in a 5.9-by-4.0-inch (HD) barrel and 2.6-pound weight. ![]() The combination of a big f-stop and ultra-wide view makes for a hefty lens. The Sigma 14mm is available for Sony cameras, as well as for L-Mount Alliance bodies. Sigma had a 14mm F1.8 DG HSM Art in the SLR days, and Sony markets the FE 14mm F1.8 GM ($1,599.99) today, but night sky photographers chase faster glass to help keep ISO and shutter combinations reasonable, as well as to more easily set focus. The Sigma 14mm F1.4 DG DN Art is the first lens we've seen with such a wide angle and aperture on a full-frame system. However, the Editors' Choice-winning Sigma 20mm F1.4 DG DN Art ($899) is more compelling because of its significantly lower price and similarly tuned optics. The lens is also a good choice for landscapes, cityscapes, and other wide-angle subjects. ![]() ![]() Astrophotography is one of the corners of the photo world that calls for specialized equipment, and the Sigma 14mm F1.4 DG DN Art ($1,599) fits that niche because of its bright maximum aperture, weather-sealed design, excellent handling of flare, manual focus lock, and heat retainer. ![]()
