EXCELLENT QUALITY

It should be noted that the Sigma 20mm F2 DG Contemporary is almost identical in size and weight to the very compact Sigma 24mm F2 I series. The sleek metal design with the Series I magnetic lens cap, manual aperture ring and exceptional build quality means that this lens makes the photographic process even more enjoyable. This ultra-sharp shooting and beautifully engineered I-Series Sigma 20mm F2 DG Contemporary reflects the essence of the I-Series: to create an even better user experience, a more enjoyable lens to own and use.

INNER FOCUS SYSTEM

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

STEPPING MOTTOR

The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.

NANO POROUS COATING

The super multi-layer coating is combined with SIGMA's unique coating technology "NPC (Nano Porous Coating)". The lens has been designed to be less susceptible to strong incident light such as backlight. "NPC (Nano Porous Coating)" incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

SUPER MULTI-LAYER COATING

SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.

1. How to choose the right lens for a mirrorless camera?

When choosing the right lens for a mirrorless camera, it is important to consider your photography needs and style. First, decide on the resolution and focusing distance you require. For portraits, lenses with a wide aperture, such as a 50mm f/1.8, are often preferred. If you enjoy landscapes, go for a wide-angle lens (e.g., 24mm). To capture distant objects, telephoto lenses (e.g., 70-200mm) are useful. Another important factor is the lens’s light-gathering ability, which affects performance in low-light conditions. A stabilization system can also be important, especially for longer lenses. It’s important to evaluate the build quality of the lens and the manufacturer's reputation. Try out several lenses and consider your future needs to choose the right and long-lasting investment in your photography.

2. Are all lenses compatible with all mirrorless cameras?

Not all lenses are universal for all mirrorless cameras. Different manufacturers may have different mounts, so it is important to check the lens compatibility with your camera. For example, lenses for Canon, Nikon, Sony, and other manufacturers' mirrorless cameras may not be interchangeable without adapters. It is also important to consider the sensor size. APS-C lenses may be disproportionately large for full-frame cameras. Before purchasing a lens, it is advisable to check the manufacturer's compatibility chart and consider the specific requirements of your camera. Adapters can allow the use of third-party lenses, but there may be some loss in functionality or quality.
