When I found out I was going to get the chance to test out the new 14-24 F2.8 DG DN | Art lens that had been completely redesigned for mirrorless, I was more than just a bit excited. Although uncooperative weather on my trip to photograph Mt. Rainier would limit my time, I was determined to make the most of it. Setting up, the fast 2.8 aperture made using live view to nail my focus on the stars feel effortless. I hit the shutter for my first exposure with the aperture wide open. I waited, checked the corners, smiled, and got right to shooting. I only had time to take a few shots, but I already couldn’t wait to see the images on a larger screen. Getting to see the sharpness across the entire frame put the quality of this lens on another level. The 14mm to 24mm may be a classic focal range for astrophotography, but there’s undoubtedly a new champion when it comes to fast, ultra wide angle zoom lenses.
What are the key differences between the Sigma 14-24mm F2.8 DG HSM | Art and 14-24mm F2.8 DG DN | Art lens
The most obvious difference is the smaller size of the new 14-24mm F2.8 DG DN | Art lens, which is designed for full-frame mirrorless cameras in Sony E mount and the L-Mount. It weighs 1.7 pounds versus the 2.5 pounds for the DSLR version. For brevity’s sake, we are going to call the new 14-24mm F2.8 DG DN | Art “the mirrorless version”, and the 14-24mm F2.8 DG HSM | Art “the DSLR version.”
Beyond the smaller size and weight, the new mirrorless version has 11 rounded aperture blades, whereas the DSLR version has nine. The mirrorless version has a stepping motor, while the DSLR version has a hypersonic motor. Each version has a different optical formula, and the mirrorless lens incorporates a new nano porous coating, which is much less susceptible to backlight incident lighting. The mirrorless version has a dedicated AFL switch on the lens barrel which can assigned different functions. Additionally, it has a built-in rear filter holder.
There is a whole lot that is similar between the two versions as well! Both lenses are class-leading ultrawide fast-aperture zoom lenses with great weather-sealing. Both offer Mount Conversion Service between released mounts, and like all Sigma lenses, are made in Japan.
