11/9/2023 0 Comments Nikon frame dslr prime lensesThe optical path of the lens is particularly impressive, especially considering how small the lens is – 13 elements are somehow crammed in there, including three high-precision glass-molded aspherical elements, one SLD (Special Low Dispersion) element and one FLD (Fluorite Low Dispersion) element. This is the widest lens in Sigma's growing range of I-series primes for Sony E-mount and Leica L-mount, and it's a solid choice for astro work. Lateral and spherical aberrations are also very well controlled.įor full-frame Canon and Nikon DSLRs, this is simply the best ultra-wide, fast-aperture zoom lens on the market, and not just for astrophotography. Vignetting is remarkably minimal and though barrel distortion is prominent at close range, it's negligible for astrophotography. Even at the shortest focal length with the widest aperture, sharpness is excellent across the entire frame, and the lens does very well to retain excellent corner sharpness at wide apertures. In our review, we found we could produce images with this lens that were nothing short of outstanding. The lens is also compatible with Sigma’s optional USB Dock for customisation and firmware updates. Build quality and handling are excellent, with a full set of weather-seals and a fluorine coating on the front element. It beats both of them for image quality and price. Maintaining excellent image quality a lens' widest aperture for astrophotography is a real challenge in an ultra-wide-angle optic, but this Samyang does exactly that – an admirable achievement.Īvailable in Canon EF and Nikon F mounts, this Sigma lens is up against own-brand legends like the Canon EF 16-35mm f/2.8L USM III and the Nikkor AF-S 14-24mm f/2.8G ED. Barrel distortion can be visible at close focus distances, but that's not an issue for astrophotography. Chromatic aberrations are negligible, while coma and astigmatism are very minimal. Sharpness is both very good and extremely consistent across the image frame. It's markedly better than Irix's rival 15mm f/2.4 Blackstone lens or a Sigma 14mm f/1.8 DG HSM Art. In our review, we were hugely impressed by how well this lens maintained its image quality when wide open, which is hugely important for astrophotography. To be fair, though, if you’re photographing the Milky Way, you’ll need clear, dry and dust-free conditions. There’s no weather-seal ring on the mounting plate to guard against the ingress of dust and moisture. The rubberized manual focus ring gives a very assured grip and has a long rotational travel with a fluid feel. The high-quality glass is neatly wrapped in a really solid casing. The lens is sold as the Rokinon SP 14mm f/2.4 in North America. So whatever you're shooting with, there should be an astro lens (or three) to suit you.įrom Korean manufacturer Samyang’s XP stable of premium manual-focus prime lenses for Canon and Nikon full-frame cameras, this 14mm f/2.4 is the most ideal for astrophotography. First, we've listed our favorite astrophotography lenses that are available for multiple mounts, and then we've drilled down into specific sections for Canon, Nikon, Sony, Micro Four Thirds, and Fujifilm. So, which lens to choose? Well, the decision will already be made to an extent by the camera you're using, which is why we've divided this guide into sections. There's plenty more to think about too, but to avoid going too long on this, we'll leave it to our astrophotography tips and how-to guides, where you can find all the astro advice you could need. Your sensor needs to be able to take in as much light as possible, but you also want to keep the ISO low so that the details of the night sky don't get lost amid image noise. Why a wide aperture? Well, at the risk of sounding obvious, you're going to be working in the dark. It needs to be a wide-angle, in order to capture as much of the sky as possible, and so you're looking at 14-20mm on a full-frame camera, 1-14mm on APS-C, or 7-10mm on Micro Four Thirds. We've dealt with the other two necessities in our guides to the best tripods and the best cameras for astrophotography – here, we're focusing on the lens.
