The new Sigma 12mm F1.4: The objective that was missing at APS-C hybrids

Sigma is one of the few third-party manufacturers to offer a full range of photo/video objectives for APS-C hybrids. In addition, these objectives are available in many frames including Canon RF! For example, With the arrival of this new 12 mm F1.4. Moreover, the Contemporary DC range is therefore made up of 5 fixed focal lengths: a 12 mm therefore, but also a 16 mm, a 23 mm, a 30 mm and a 56 mm, all offered with an opening of F1.4. For example, It also incorporates 3 zooms: an 18-50 mm F2.8, a 17-40 mm F1.8 and a 16-300 mm. For example, This range. Therefore, on certain frames, is much more complete than that offered as a native by box manufacturers: we think of canon of course, but also Sony to a new sigma 12mm f1.4: objective certain extent.

The new Sigma 12mm F1.4 DC | Contemporary is offered in Sony E mount, Canon RF and Fujifilm X.

With an APS-C hybrid, a conversion coefficient of around 1.5x must be applied to the focal lengths to obtain the 24×36 mm equivalent focal length. Consequently, This constraint is clearly an advantage with long focal lengths. Thus, a 200 mm automatically turns into a 300 mm equivalent. On the other hand, as far as the Grands Angles are concerned, it is more delicate. With this 12 mm. Sigma therefore provides an answer to get the ultra-angle in APS-C since it is equivalent to an 18 mm. This type of focal length is therefore very effective for photography of landscapes. architectures for example, but also for astrophotography.

Careful optical construction – New sigma 12mm f1.4: objective

The very large opening F1.4 provided by a circular diaphragm with 9 strips makes it possible to obtain marked depth of field effects. to be able to work very comfortably in small light or night light conditions. Note that this lens incorporates a manual diaphragm ring that can be made continuously if necessary for video use.

The objective is based on an optical formula composed of 14 lenses divided into 12 groups with 2 SLD glasses and 3 aspirial lenses. Sigma provides optimized coma correction to ensure clarity. details on the external areas of the images: one plus for the star photo. The flare and the ghost images were also reduced to a minimum.

This 12 mm is very compact and light. Count a size of less than 7 cm and 225 g on the scale. It is therefore very handy by hand and perfect for video use on for example a gimbal. The objective is protected against bad weather with reinforced protection against dust and humidity. It uses an autofocus motorization of a step by step not very precise. fast, suitable for both photo and video use. For the video, the phenomenon of “focus breathing“has been deleted.

Availability and price

The new Sigma 12mm F1.4 DC | Contemporary will be available in Canon RF, Sony E or Fujifilm X mount. It will be available from September 4 and offered at a price of € 599.

First opinion

This is excellent news for users of APS-C hybrids to see this new new sigma 12mm f1.4: objective high-end goal arrive. It makes it possible to extend the field of possibilities of their case. their photographic practice with access to the world of the ultra-angle equivalent 18 mm.
