Ligthweight and compact, the 100-400mm from Sigma offers impressive image quality and autofocus (which is also great in video)

Sigma has just announced their highly anticipated and first ultra-telephoto zoom lens for full-frame mirrorless cameras. The new Sigma 100-400mm f/5-6.3 DG DN OS boasts many advanced features and a lightweight compact design. Not to mention an affordable price tag considering the features it brings to the table.

Moreover, Sigma refers to their latest zoom as an “ultra-sharp, ‘Handy Tele Master’” suitable for wildlife, professional, as well as enthusiast photography and video applications.

Designed for full-frame mirrorless cameras (in the L-mount and Sony E-mount ecosystems), the new Sigma 100-400mm is said to even rival the image quality out of the well-respected Sigma 24-70mm f2.8 Art lens.

Advanced Optical Design and 1.4x and 2x Teleconverters

Naturally for a lens this compact and with such impressive range, there will be quite a lot of glass inside. In addition, the lens’ optical design incorporates a whopping 22 elements arranged in 16 groups. Also, the design includes one FLD and four SLD elements used for the effective correction of aberrations and distortions.

Built on the latest optical design technology and optimised for mirrorless systems, the new 100-400mm ensures the same high-resolution image quality from corner to corner. As well well as right across the entire zoom and focus range.

Furthermore, the lens is compatible with the two new Sigma teleconverters – 1.4x, and 2x; thus giving photographers a super-telephoto angle of view with a focal length of up to 800mm. And the best part is that Autofocus is available even with the teleconverter is attached.

High-Speed AF and “Dual Action Zoom”

Furthermore, the new ultra-telephoto features a stepping motor system that is optimised for both phase detection AF and contrast AF. This makes for some very smooth AF eye-tracking in both stills and video.

In addition to high-speed, smooth AF controlled by a stepping motor optimised to the latest algorithms, the SIGMA 100-400mm incorporates powerful built-in image stabilisation (OS), which offers a four-stop advantage.

When combined with a camera body that also has image stabilisation built-in, the lens corrects pitch and yaw axis rotations, providing even more powerful stabilisation.

The lens features an AFL button, to which the user may assign a range of different functions, and a focus limiter switch that allows the user to optimise the AF range depending on the subject distance.

Sigma USB Dock for Fine Tuning Focus

When connecting the lens to a SIGMA USB DOCK (sold separately, L-Mount only), users can use SIGMA Optimization Pro software to adjust the amount of focus movement.

The new lens also supports ‘dual action zoom’, which allows users to zoom in or out by turning the zoom ring, or if preferred by pushing or pulling the lens hood, enabling fast intuitive adjustments to focal length.
