Sigma 24mm f/1.4 Art lens field tested: Wide-angle winner

While not as new or celebrated as its bigger sibling, the , the seemed like a worthy candidate to test with my new . After using it off and on for a few weeks, I’m impressed with its combination of features, image quality, and value. It delivers excellent results for a , compared to $2,000 for the .

Build and Features

Like all of Sigma’s Art and Sport lenses, the is very-well built, with a pro-quality finish. The lens has 7 ED elements among its 15 elements, arrayed in 11 groups. Two of them are aspherical, and specialized multi-coatings are used to reduce ghosting and flare. It includes a high-speed focusing motor and has manual focus override. It also features a blissfully-standard 77mm thread for filters. Like the other Art lenses, it can be used with Sigma’s unique USB dock, that can fine-tune lens settings and upgrade firmware if needed.

Image Quality

As tested by DxOMark, the was a top performer among alternatives when paired with the (then) top-of-the-line body. It did a great job across the board in DxOMark tests comparing it to the Zeiss and Nikon versions:



If you want to see how well the lens would perform on your camera, or check out its detailed test results, . Numbers aside, I certainly couldn’t find anything to complain about in the image quality from this lens. It did well in a variety of tough lighting conditions, with very limited flare, and provided all the detail I could hope for.

To give you an idea of how little distortion this lens has, I turned off the Lens correction feature of Adobe Camera Raw when processing it. Even with no correction distortion is barely visible. Once you turn on correction, it disappears completely (of course perspective issues and volume deformation don’t magically disappear – here I’m talking about barrel & pincushion distortion):

This is with Lens Correction turned off, and also provides an excellent example of the D850’s high ISO performance

Sample Image Gallery

I’ve been testing my with both the and the . I’ve posted a gallery of sample images from the two lenses. Some are original JPEGs and some are Raws that I saved from Adobe Camera Raw (Lightroom and Optics Pro don’t yet support RAW from the D850) as sRGB JPEGs, resized for easier web viewing, and with screen sharpening applied:
