SIGMA LAUNCHES NEW LINE OF COMPACT MIRRORLESS LENSES

MAKING THE MOST of what can be achieved in designing lenses for mirrorless cameras, Sigma has introduced a new line of compact premium primes in the Sony FE mount and the L mount (which it shares with Leica and Panasonic). Designated the I series, there are three new lenses joining an existing model, the 45mm f/2.8 DG DN, that now becomes an I series lens. All four are part of Sigma’s Contemporary line – one of the three ‘Global Vision’ classifications that the lens maker uses to primarily signify the application (the other two are Art and Sports).

The three new I series lenses are a 24mm f/3.5 DG DN, a 35mm f/2.0 DG DN and a 65mm f/2.0 DG DN. All three have all-metal barrel constructions with weather sealing, manual aperture collars and a classical ribbed pattern on the control rings and the lens hoods. A new feature is magnetic mounts for the quick attaching and removal of lens caps.

The optical designs utilise the size reductions made possible by the shorter flange back distance of mirrorless cameras, while also optimising performance aspects such as uniformity of corner-to-corner sharpness and brightness. High-performance glass-moulded aspherical elements are used in both the 24mm and 35mm models, and these help correct for spherical and comatic aberrations, and also distortion. All three new I series lenses employ elements with super-low dispersion (SLD) characteristics to correct for a variety of aberrations, including axial chromatic. Autofocusing is performed via stepper motors to ensure fast, smooth and near-silent operation.

The Sigma I series lenses are available now, distributed by C.R. Kennedy & Co. The 24mm f/3.5 DG DN Contemporary is priced at $726 for Sony FE and $699 for L mount, the 35mm f/2.0 DG DN Contemporary at $924 (both FE and L mounts) and the 65mm f/2.0 DG DN Contemporary at $1,045 (both FE and L mounts).
