Sigma has announced the launch of its first ultra telephoto lens specifically for full-frame mirrorless cameras, as well as a pair of teleconverters, a new USB dock and a new mount options for three of its prime Contemporary lenses.

100–400mm F5–6.3 DG DN OS Contemporary

While this new lens might look similar to its previous 100-400mm lens, the 100-400mm F5-6.3 DG DN OS Contemporary has been designed ‘from the ground up for mirrorless camera systems.’ Specifically, the lens will be available in Sony E-mount and L-mount.

It’s designed to cover fulll-frame image sensors and is constructed of 22 elements in 16 groups including one low dispersion element (FLD) and four special low dispersion (SLD) elements. It uses a stepping motor for autofocus, has a nine-blade aperture diaphragm, a minimum aperture range of F22–29 and a 67mm front filter thread. At 100mm it has a minimum focusing distance of 112cm (44”) and at 400mm it has a minimum focusing distance of 160cm (63”). The lens measures in at 86mm (3.4”) diameter, 197mm (7.8”) long and weighs 1,135g (40oz).

The Sigma 100-400mm F5-6.3 DG DN OS Contemporary is currently available to pre-order for Sony E-mount (Adorama, B&H) and L-mount (Adorama, B&H) for $950. The first units should start shipping on July 10.

Sigma Teleconverter TC-1411 and TC-2011

In addition to its mirrorless ultra-zoom, Sigma has also announced two new L-mount teleconverters: the TC-1411 (1.4x) and the TC-2011 (2x). Sigma says these two teleconverters are ‘Designed to complement Sigma’s renowned optical formulas’ and feature a dust- and splash-proof design ‘comparable to that of the Sigma Sports line lenses.’

The TC-1411 (1.4x) and TC-2011 (2x) are currently available to pre-order for $400 (Adorama, B&H) and $430 (Adorama, B&H), respectively, and should ship on July 10 alongside the 100-400mm F5-6.3 lens.

Sigma USB Dock UD-11

New lenses and teleconverters also mean new docks for updating firmware and adjusting settings. Sigma’s new USB Dock UD-11 models use a USB Type-C connection and are available for Sigma L-mount and Canon EF-M mount mirrorless lenses. As with Sigma’s other docks, the UD-11 models makes it possible to update firmware and customize settings on Sigma lenses with these mounts.

These EF-M and L-Mount docks are also available to pre-order starting today for $59 (Adorama, B&H) with an expected shipping date of July 10.

16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses

Sigma has also announced it’s made its three F1.4 mirrorless lenses available for L-mount camera systems. The 16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses are identical to their Sony E-mount, Canon EF-M mount and Micro Four Thirds predecessors, and are currently available to pre-order for $450 (Adorama, B&H), $340 (Adorama, B&H) and $480 (Adorama, B&H), respectively, with a July 10 shipping date.

It's worth mentioning that the only current APS-C cameras that utilize the L-mount, and therefore would be most appropriate for this trio of lenses include Leica's TL2 and CL mirrorless cameras released in 2017. But for full-frame L-mount users who primarily shoot video, these lenses do make for compact, affordable Super 35 lens options.
