Hands on Sigma 20mm F1.4 DG DN Art and Sigma 24mm F1.4 DG DN Art Lenses Wide and ultra wide prime fast lenses from Sigma

Sigma announced two fast wide-angle prime lenses – the Sigma 20mm F1.4 DG DN Art and Sigma 24mm F1.4 DG DN Art lenses.

Only last week we posed an extensive review and comparison between the Sigma 20mm f/2 vs. Sony 20mm f/1.8 lenses. The Sony came up with the upper hand but now Sigma has a new contender on both the 20mm and 24mm spots which are either faster and/or less expensive (how they actually perform and what they offer you will see in the following lines and hopefully in our upcoming review later this year).

Sigma 20mm F1.4 DG DN Art

The new Sigma 20mm F1.4 DG DN Art isn’t the first 20mm f/1.4 Sigma has in its lineup. The existing model announced about 7 years ago was a heavy DSLR lens that received an E mount which made it weigh closer to 1kg. The new DN (or mirrorless) version has a completely new and much smaller and lighter design which works with E and L mounts only.

So what can we tell you about the Sigma 20mm F1.4 DG DN Art? this lens has 17 elements in 15 groups including 2 SLD glass elements, and 3 aspherical elements. It also has 11 aperture blades and it supports 82mm front filters but also has an option for back filters.

The lens is much lighter than the previous version weighing in at just 635g and quite a bit shorter at just over 11cm. It has a min focus distance of 23cm and a maximum macro magnification of 1:6.1.

The lens has an AF/MF switch, a programable AFL button, a lock switch for the focus ring (important for astrophotographers for example), and a de-click switch for the aperture ring. The aperture ring which is at the back of the lens also has an automatic mode.

Below are the main specs for the new Sigma 20mm F1.4 DG DN Art lens:

  • Lens: 20mm f/1.4 lens with FF coverage.

Sigma also had an older 24mm f/1.4 designed originally for DSLR cameras which is heavier (and more expensive). The new Sigma 24mm F1.4 DG DN Art has 17 elements in 14 groups including 1 SLD glass, 2 FLD glass, and 4 aspherical elements. It also has 11 aperture blades and it supports 72mm front filters.

Just like the 20mm lens, the 24mm has an AF/MF switch, a programable AFL button, a lock switch for the focus ring (important for astrophotographers for example), and a de-click switch for the aperture ring. The aperture ring which is at the back of the lens also has an automatic mode.
