Originally introduced in October, 2021, the SIGMA 18-50mm F2.8 DC DN | Contemporary is the first mirrorless- exclusive, APS-C format standard zoom lens from SIGMA Corporation. This incredibly compact new lens offers a full-frame equivalent 27-75mm focal range. At time of announcement, it was available for both Sony E-mount and L-Mount systems. The Fujifilm X Mount version was announced in November 2022, and now SIGMA is pleased to announce this as the first lens to be released for the Canon RF Mount.
Less than 3 inches (74.5mm) long and weighing just over 10 ounces (290g), it is the smallest and lightest F2.8 standard zoom for crop-sensor mirrorless cameras (since time of original release, and effective June 2024).

This new lens is designed for APS-C camera users who want a compact, large-diameter workhorse zoom lens that is ideal for travel and day-to-day shooting. It is the perfect step up from the typical kit lens with better optical performance, constant F2.8 aperture, quiet stepping motor, and 1:2.8 macro capability (at 18mm). It is also an excellent option for video use thanks to its versatile range, excellent overall performance, and small, gimbal-friendly size.

Key Features:

• Smallest and lightest F2.8 standard zoom for crop-sensor mirrorless cameras (as of Oct. 2021).
• Versatile focal range and excellent optical performance make it a great choice for a wide variety of
  uses, including travel, daily shooting, food photography, landscapes, vlogging, etc.
• 3 high-precision glass-molded aspherical elements -- coupled with the minimization of the total number of elements -- provide superb optical quality without excessive weight.
• In-camera aberration correction further eliminates optical imperfections such as distortion and
  vignetting.
• Thermally Stable Composite (polycarbonate with thermal characteristics similar to aluminum) barrel
  construction, with slim internal metal parts, offer light weight and functional strength.
• 7 rounded aperture blades offer smooth background blur (bokeh).
• Stepping motor provides swift, accurate and quiet autofocus for both still and video shooting.
• Measured from the sensor, it achieves a minimum focusing distance of 4.76 inches (12.1cm) and a
  maximum magnification ratio of 1:2.8 at the wide end.
• Working distance of just over an inch (2.7cm) from the front element at 18mm.
  NOTE: We recommend removing the lens hood for this style of ultra-close capture and to be mindful
  about not touching the front element to the subject.
• Includes a petal-type hood to reduce ghosts and flaring, while protecting the front lens element.
• High-precision, durable brass bayonet mount with dust and splash-resistant structure.
• Compatible with SIGMA USB DOCK UD-11 (sold separately / for L-Mount only)
• Made in Japan
