The SIGMA I series introduces compact, beautifully designed, high-performance optics for mirrorless camera systems. In its first collection, SIGMA introduces a high-performance 65mm lens to the Contemporary line-up, which combines excellent resolving power with a small body that is perfectly weighted for mirrorless systems.
The all-new I series 65m F2 DG DN | C, which is available for L-Mount and Sony E-mount cameras, blends a very compact design with an unusual but versatile focal length that is much loved by both photographers and film-makers. This ultra-sharp full-frame optic is a perfect mid-point between standard primes and classic portrait lenses and is ideal for portraits, weddings, short-telephoto landscapes, street photography and astrophotography.
New standards of optical performance for the Contemporary line
The 65mm F2 DG DN | Contemporary brings to the table the highest level of optical performance even at its maximum aperture of F2. Axial chromatic aberration, which tends to be noticeable with medium and telephoto lenses and cannot be effectively reduced in-camera, is corrected thoroughly with the use of SLD glass, allowing it to resolve extreme detail.
A pair of glass-moulded aspherical lenses are used to correct spherical and comatic aberration, as well as astigmatism, while also helping make the optical configuration smaller in size. A combination of the latest optical design and advanced processing technology gives the 65mm F2 DG DN | Contemporary its excellent optical performance as well as compact size.
In addition to the beautiful bokeh effect thanks to the control of spherical aberration, the reduced effect of vignetting help curb lemon-shaped or swirly bokeh and give photographers greater control over the out-of-focus areas of their images. And SIGMA-standard anti-ghosting and anti-flare technology ensure high-end performance in backlit conditions.
An ultra-sharp portrait lens with little flare or ghosting
The 65mm focal length, exceptional optical performance and wide aperture of F2 make this lens is ideal for portraits. SIGMA-standard anti-ghosting and anti-flare technology ensure high-end performance in backlit conditions.
Beautiful bokeh with near-circular highlights
The lens displays a particularly attractive bokeh effect thanks to the control of spherical aberration and its nine rounded diaphragm blades, with near-circular out-of-focus highlights across the frame and at the widest aperture of F2.
Introducing a new photographic experience for mirrorless users
The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve. One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 65mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.
Simultaneously, SIGMA is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of taking pictures when they choose to own a camera and lenses. SIGMA’s excellence in development and processing technologies has been built up since its founding in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision range in 2012. With this as a base, SIGMA has given careful thought to how photographers use and enjoy their lenses, including optical design, advanced functionality, superb build quality and the experience of picking up and using the lens, and with all of this carefully considered, the I series was born.
