Ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture, and events, the 18-50mm f/2.8 DC DN Contemporary Lens from Sigma is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. Offered here with a Sony E-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75 and a wide constant aperture of f/2.8 throughout the entire zoom range. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimize the total number of elements for superb optical quality without excessive weight. Autofocus is exceptionally fast and quiet thanks to the lens's stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8", enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality.

How does this compare with the Sony Zeiss f4 16-70 Zoom in terms of quality of images?
Compared to the Sony Vario-Tessar T* E 16-70mm f/4 ZA OSS Lens, B&H # SO16704, the Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E is sharper and has a larger aperture, but its zoom range is shorter. If you don't need the longer zoom range, then the Sigma could be more ideal.

What is a contemporary lens?
What is a contemporary lens?
Sigma's Contemporary line are lenses designed to require digital lens corrections for things like distortion and lateral chromatic aberration. This allows the lens to be smaller and cheaper. But if you turned lens corrections off, you would see the distortion quite clearly. The line above the Contemporary line, the Art line, does try to correct all optical imperfections in-lens and not require digital corrections, but the lenses are much larger and more expensive because of it.

I have the Sony 18-135 currently. Is this as good as or better than the Sony lens?
In terms of image quality, the Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E is an upgrade over the Sony E 18-135mm f/3.5-5.6 OSS Lens, and it has a larger aperture for better low-light performance or background blur. However, the Sigma lens has a shorter zoom range, so if you're typically shooting above 50mm on the 18-135mm this would not be recommended.

Does the focus ring work in the same direction as sony lenses?
The Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E does not rotate in the same direction as native Sony lenses. When you rotate the focus ring clockwise on Sony native lenses it focuses toward infinity. When using Sigma lenses, rotating the focus ring clockwise will focus toward close focus instead.

Will this be avaliable for Canon EF mount?
It's a DN, meaning it's for mirrorless cameras only. Surprisingly, it also isn't available (yet?) in the Canon M mount.
