SIGMA 24mm f/2 Contemporary DG DN Sony

I SERIES – PREMIUM COMPACT PRIMES – FOR MIRRORLESS CAMERAS

 
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 the impressive results it can achieve.
One of the main advantages of mirrorless cameras is their smaller form factor, and this new 24mm optic is designed to blend seamlessly into these more compact systems without sacrificing performance. This combination of excellent optical quality with exceptional portability, which was previously not possible with DSLR systems, will bring new opportunities for this and future generations of photographers.
Simultaneously, SIGMA is aware that in this day and age where we have such a great diversity in what we use to photograph, as represented by smartphones, people are looking 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 since its founding in 1961 and has become even more sophisticated with the introduction of SIGMA Global Vision in 2012.
With this as a foundation, SIGMA thought carefully about how photographers use and enjoy their lenses, including optical design, advanced functionality, build quality, and the experience of picking up and using the lens, and with all of this carefully considered the I series was born.

NEW OPTICAL PERFORMANCE STANDARDS FOR THE COMTEMPORARY LINE
The SIGMA 24mm F2 DG DN | Contemporary such as the SIGMA 35mm F2 DG DN | Contemporary and the SIGMA 65mm F2 DG DN | Contemporary, it combines the highest level of optical performance even at its maximum aperture of F2 and a well-balanced body.
The lens uses two SLD glass elements and one FLD glass element to correct axial chromatic aberration, which is a particular concern with bright lenses.
It also incorporates two aspherical elements molded from high-precision glass, made possible by the processing technology of SIGMA's only production facility in Aizu. This allowed the total number of lens elements to be reduced and the size and weight of the lens to be reduced, providing excellent correction of various aberrations.
Anticipating the applications of wide-angle lenses, SIGMA's optical designers ensured that the lens resolution was extremely high and uniform from the center to the periphery of the image. The sagittal coma reflex is also well suppressed, giving the lens a high degree of rendering power that makes it ideal for night sky photography.
The AF drive system incorporates a quiet, high-speed stepper motor. This allows photographers to capture every detail of the spacious 24mm scene with lightweight AF.
