![]() It is important to be mindful of this while using the lens to ensure the area is clean at all times. Like some of the other Sigma Art-series lenses, the 24mm f/1.4 Art, unfortunately, does not have a rubber gasket on the mount, meaning there is the risk of dust, moisture, and other debris to get between the lens and the camera mount. The lens focuses fast and is equipped with a high-quality hyper-sonic motor, found on other Sigma lenses, providing fast and quiet (i.e. The focus ring, located on the front of the lens barrel, is very smooth and easy to rotate which is important for manual focusing. The premium glass elements bring aberrations and distortion to a minimum, which is a common issue with many wide-angle lenses. The Sigma 24mm F/1.4 offers impressive sharpness characteristics and offers an optical formula comprising 15 total elements in 11 groups, four of which are low dispersion, three that are low-dispersion (FLD), and two that are aspherical. The Sigma 24mm F/1.4 Art lens attached to my Canon EOS Ra Mirrorless body (using an adapter). One of the big selling features for me was the 77mm lens diameter, which allows me to utilize my existing collection of UV and ND filters. This is lens is also suitable for many other types of photo/video work, such as weddings, landscape photography, and event photography. An aperture of f/1.4 is a very attractive spec for amateur astrophotographers who capture images and videos at night. The 24mm lens is the second widest prime lens in the Sigma Art series, ideal for low-light photography. The lens I use includes the Canon EF-mount, which I can also use on my RF-mount Canon EOS Ra using a Canon EF – EOS R adapter. The Sigma 24mm f/1.4 Art lens is a professional-grade wide-angle lens part of the overall Art-series by Sigma, which are great budget-friendly alternative to similar, and more expensive Canon, Nikon, and Sony lens options. The stock 6D II is used mainly for videography with the Sigma lens, while the EOS Ra is used for long-exposure night sky imaging exclusively. I have a Canon EOS 6D Mark II (stock), and a Canon EOS Ra (astrophotography) camera. I have used the Sigma 24mm F/1.4 Art Lens on my full-frame Canon cameras for astrophotography. Take a look at the example image below to see the difference between a single frame, and the final stacked image. When paired with a full-frame astrophotography camera, the results are simply stunning.įor the image above, my exposures were shot at ISO 3200 at F/2.8. My wife and I rented an Airbnb at a dark sky location ( Bortle Scale Class 3), to enjoy an unspoiled night sky.Ģ4mm is an ideal focal length for astrophotography applications, particularly nightscape photography. To create the image above, I captured multiple 90-second exposures on a portable star tracker (Sky-Watcher Star Adventurer). The photo shown below was captured using the Sigma 24mm F/1.4 lens and my Canon EOS Ra mirrorless camera. In this article, I will share my results using the Sigma 24mm F/1.4 Art lens for astrophotography. The lack of image stabilization will likely be a deciding factor for those looking to use this lens for video work, but I have found it to be very useful when filming in low-light situations despite this feature. The lens isn’t perfect, but it is an exceptional value and has impressive qualities that amateur astrophotographers can appreciate. The reviews on B&H Photo indicate that Nikon and Sony camera owners have had a positive experience with this lens as well. I’ve used the lens on my Canon DSLR and Mirrorless cameras, and have found it to be one of the most useful lenses I own. No optical corrections were made in post-processing to show the impressive ‘out-of-the-box’ performance of this lens.Ĭlick the image for a larger view to appreciate the optical performance of the Sigma 24mm F/1.4. The stars are not bloated, and they are exceptionally well color-corrected. The modestly edited stack of images below shows the incredible performance of this lens from an optical standpoint. ![]() The Sigma 24mm F/1.4 is perhaps the most impressive lens for astrophotography overall, rarely due to its incredibly fast aperture. Over the years I have used a number of great camera lenses for astrophotography from the Rokinon 135mm F/2 to the Canon EF 300mm F/4L. There is just something about that 24mm focal length that captures the night sky at just the right field of view. While there are a few lenses in their art-series line-up that are well-suited for low-light photography, I consider the 24mm version to be the ultimate choice for astrophotography. With an f-ratio of F/1.4, this Sigma art series lens can pull in a lot of light under a dark night sky. ![]() The Sigma 24mm F/1.4 lens is an interesting choice for astrophotography, particularly wide-angle Milky Way photography.
