Sigma presents the 28-45mm f/1.8 DG DN Art lens, the world's first zoom lens for full-frame mirrorless cameras with an f/1.8 aperture throughout the zoom range. It features top-tier optical performance and a video-friendly design. The wide to normal focal range means a lighter kit bag without compromising image quality.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Item

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

    Fixed Aperture Zoom

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

  • Maximum Aperture (f)

    Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.
    2. The most open aperture of a lens is called the maximum. The more open the aperture (smaller f-number), the shallower the depth of field.

Description

Description

Sigma presents the 28-45mm f/1.8 DG DN Art lens, the world's first zoom lens for full-frame mirrorless cameras with an f/1.8 aperture throughout the zoom range. It features top-tier optical performance and a video-friendly design. The wide to normal focal range means a lighter kit bag without compromising image quality.

Design and Performance

  • 18 elements in 15 groups, with 3 aspherical and 5 Special Low Dispersion elements.
  • Minimizes flare and ghosting, suppresses aberrations.
  • Optical performance that rivals other Sigma Art series.
  • Rounded 11-blade diaphragm for sharpness and smooth bokeh.
  • Minimum focusing distance of 11.9" throughout the zoom range.
  • Maximum magnification ratio of 1:4 at the longest focal length.

Video Production

  • Bright f/1.8 aperture and zoom range from wide to normal.
  • Ideal tool for single-shooter, run-and-gun setups.
  • Internal zoom design that maintains length during use.
  • Suppresses focus breathing for smooth motion.
  • Silent and precise linear actuator autofocus.
  • Manual focus with click and lock mechanisms.

    This review is about the mount: Sony E

    It has a stiff focus ring and during focus pull at the beginning (rarely) it loses the field, meaning when someone changes the focus from far to near, the focus suddenly goes far again. Overall, an excellent lens and the 1.8 is worth every penny. If someone has the money, it's better to get the G Master 28-70 f2
