Just in time for CP+, Sigma has revealed two new wide-angle additions to its product lineup: the 24mm f/1.4 DG HSM Art Lens and the dp0 Quattro Digital Camera. Designed for full-frame DSLRs, the 24mm f/1.4 is a welcome addition to the extremely well-received Art line of lenses, while the dp0 Quattro expands the APS-C advanced point-and-shoot camera line with an ultra-wide 14mm (21mm equivalent) fixed lens.
24mm f/1.4 DG HSM Art Lens
Sigma has been on a roll lately with its full-frame Art series prime lenses, each featuring the latest optical technologies, as well as performance that has consistently wowed users with their quality. The 24mm f/1.4 DG HSM Art lens seems to be no exception, with its fast f/1.4 aperture, multiple specialized elements, and a Hyper Sonic AF Motor. On top of this, the lens is extensively tested using Sigma’s A1 MTF measuring system, at the factory in Japan. This design ensures it will hold up in the most demanding situations.

With a fast f/1.4 aperture, this lens will be in high demand for low-light and indoor applications, and the wide angle of view makes it extremely well suited for shooting landscapes, architectural interiors, or astrophotography, among others. Of course, this aperture enables shallow depth of field with very pleasing “bokeh,” or out-of-focus highlights, thanks to the implementation of a nine-blade diaphragm. And, though it was designed for full-frame cameras, it will offer an equivalent focal length of about 36mm when used on an APS-C camera.
The 15 element in 11 group optical construction features both F Low Dispersion (FLD) and Special Low Dispersion glass elements, which help control chromatic aberrations. Aspherical lenses are placed in the rear of the lens for better performance when shooting with a wide-open aperture, and also minimize distortion and vignetting, along with correcting for axial chromatic aberrations and sagittal coma flare.
Operational notes for the lens include full-time manual focusing by just rotating the physical focus ring, and a minimum focus distance of 9.8" for working in tight spaces. When using autofocus, the lens has a hypersonic motor (HSM), which is fast and silent. As with the majority of the “Global Vision” lenses, it is compatible with Sigma’s USB dock and Optimization Pro software for updating firmware and fine-tuning the focus system. This lens is eligible for the Sigma Mount Conversion Service.
This lens will be available for Nikon F, Canon EF, and Sigma SA mounts.
dp0 Digital Camera
Sigma has made the dp Quattro series a quartet with the addition of the ultra-wide-angle 14mm (21mm equivalent) dp0 Digital Camera. This complements the existing dp1, dp2, and dp3 models, with their respective 19mm (28mm), 30mm (45mm), and 50mm (75mm) lenses by offering users an even wider 91° angle of view, great for landscapes and architecture.

Ensuring optical performance, the 14mm f/4 lens of the dp0 uses four F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements, along with two aspheric lenses, including a wide double-sided aspheric lens. All of this glass reduces chromatic aberrations and distortion while improving overall sharpness that maximizes the capabilities of the unique sensor design.
As with the rest of the Quattro series, the dp0 uses a 29MP Foveon X3 image sensor and the TRUE III processing engine. The APS-C CMOS sensor is able to record full color information vertically through a stacked sensor design instead of the use of various pixel arrays. This eliminates the need for color filters and a low-pass filter, offering lower noise and greater detail that creates imagery equivalent to a 39MP Bayer sensor.
Adding this new camera to the lineup allows photographers to find a model more easily that works best for their needs and purposes.
