Sigma 18-50DN Build, Handling, and Features As always, this is a completely independent review. Thanks to Sigma Canada (Gentec) for sending me a pre-release loaner copy of this lens. Despite being beautifully compact, Sigma has packed some excellent optics into this lens.įollow Me Patreon | My Newsletter | Instagram | Facebook | DA Merchandise | Flickr | 500px It is only 62mm in diameter, 76.5mm in length, and weighs only 290g. This made for a great slot for Sigma to slide into with their new Sigma 18-50mm F2.8 DC DN lens, as it covers this popular zoom range while delivering excellent image quality, a constant F2.8 aperture, and at an extremely compact size and weight. This is, frankly, bigger than what many people are looking for. Yes, Sony does have a premium zoom in this space, but the Sony 16-55mm F2.8 G lens costs a whopping $1400, which is more than what most of the Sony APS-C mirrorless cameras cost! Tamron more recently released an excellent 17-70mm F2.8 VC lens, a lens I reviewed very favorably, but it is also very much on the large side of things at nearly 120mm long and weighing 525g.

Ironically, however, while Sony mirrorless cameras have quickly proliferated with more lens options than I’ve ever seen before, one of the basics missing was this very popular zoom and aperture combination that allows APS-C shooters to upgrade their kit lenses.

Low light photography, shallow depth of field shots, and that more professional look where the subject is more isolated from the background. Yes, the price was more expensive, and yes, the lens was a little heavier, but the constant F2.8 aperture opened up so many more photographic possibilities. Before long I ended up where many photographers of that era did – with a Tamron or Sigma zoom that covered a similar zoom range but with a constant F2.8 aperture. It was clunky in operation, had a very slow and limiting maximum aperture range, and was uber-cheap in construction. 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.I entered the world of DSLRs back with Canon T1i, which came with a kit 18-55mm F3.5-5.6 IS lens. 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. Together they minimize the total number of elements for superb optical quality without excessive weight. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Offered here with a Sony E-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. 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.
