Sigma presents its first ultra-tele zoom lens especially for mirrorless full format cameras. The 100-400mm F5-6.3 DG DN OS Contemporary will be released for L-Mount and the Sony E-Mount and is aimed primarily at photographers -- the stepper motor will be optimized for both phase detection AF and contrast AF. Sigma does not provide any information on the volume of the motor; it does not appear to be an ultrasonic motor. The close-up limit is 112 cm (W) and 160 cm (T). The aperture has 9 blades.
The lens construction of the telephoto zoom consists of 16 groups and 22 elements, including an FLD lens and four SLD lenses, which are intended to effectively correct aberrations and distortion. The lens is optically stabilized. It weighs only 1,135g and measures approximately 86 x 197.2 mm (when the zoom is retracted). The filter diameter measures 67mm.
In conjunction with the also newly announced SIGMA Tele-Converters TC-1411 and TC-2011 (available as an option and only for L-Mount), which have also been developed exclusively for use on mirrorless cameras, the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary then provides the photographer with a "super-tele image angle" with a focal length of up to 800mm. The AF functions should also be retained in combination with the tele-converters.
The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary is to be launched in July for 999 Euro.
In addition, the portfolio of L-mount lenses with three fast Contemporary focal lengths for cameras with sensors in APS-C format will be expanded. The standard lens 30mm F1.4 DC DN | Contemporary (for 3999 Euro), the wide-angle lens 16mm F1.4 DC DN | Contemporary (for 449 Euro) and the medium telephoto lens 56mm F1.4 DC DN | Contemporary (for 429 Euro) will also be available for this mount from July. So far, these lenses were available for MFT-Mount, Sony E-Mount and Canon EF-Mount.
