AGENDA NEWS Sigma’s Z mount trio
SOFT CHOICE FOR PANEL USERS DoPchoice now has a universal Snapbox to fit a variety of flat panel lights and sculpting tools for Sumomax and Kelvin Epos. The modifier for flat panel lights will fit Kino Flo Freestyle Air, Air Mini and Air Max, Litegear LiteMat 1, 2L and 4, and Exalux Ledzep 1x4 and 2x4 panels. A self-tightening Snap system allows fast mounting, and the smooth diffusion box mounts over the flat light panel frame and attaches to the fixture’s hook-and-loop fastening for light softening and diffusion. The Sumomax kit includes a Snapbag that straps directly to the light’s hexagonal housing, creating a circular 90cm/35.4in front. It features a reflector and skirt to modify spread and diffusion. To accessorise the Bowens-mount Kelvin Epos, DoPchoice’s Rabbit-Rounder adapter mounts an assortment of Snapbags, like DoPchoice’s rectangular Snapbags in small and medium sizes, 3ft and 5ft Octas, and lanterns. No prices have yet been set. dopchoice.com
Japanese lens giant Sigma has revealed its first three lenses to fit Nikon Z mount mirrorless cameras. These wide-aperture optics from Sigma’s Contemporary series are for crop-sensor cameras like the Z 50 and Z fc, so full-frame models need to be used in APS-C mode. Said lenses are the 16, 30 and 56mm, which all have a maximum f/1.4 aperture and nine blades for smooth bokeh. The 16 and 56mm cost £449/$499 each, while the 30mm is £349/$399. The widest lens has the most complicated optical design, with 16 elements in 13 groups, and weighs the most at 420g/0.93lb. It has a 67mm filter thread and comes with a petal lens hood. The 56mm optic has a 55mm thread, weighs 295g/0.65lb and has ten elements in six groups, while the 30mm comes in lightest at 285g/0.63lb, with a simple nine elements in seven groups and 52mm filter
thread. Both have straight lens hoods. They are currently available in five other mounts – Sony E, Fujifilm X, Canon EF-M, Micro Four Thirds and Leica L. CROP-SENSOR RANGE EXPANDS
ZED HEAD The Nikon Z mount mirrorless series gets a wider choice of glass, as Sigma reveals its first trio to suit – but they are all APS-C versions
A brand-new 23mm lens from Sigma’s Contemporary range has a fast f/1.4 aperture and comes in Sony E, Fujifilm X and Leica L fitments. With 13 elements in ten groups, including three SLD and two aspherical, it is made to produce sharp images even in extreme backlit environments. Designed exclusively for APS-C mirrorless cameras, the lens has a compact, lightweight body weighing just 340g/0.75lb. It features a quiet, high-speed stepping AF motor and can be used with AF modes such as focus tracking and eye detection. A large focus ring enables fine-tuning of focus with Dynamic Manual Focus (DMF). The lens supports switching between non-linear and linear focusing when customised using the Sigma USB dock, for L-Mount only.
The £449/$549 lens comes with a petal-shaped lens hood, is dust- and splash-resistant and has a rounded, nine-blade iris. sigma-imaging-uk.com
Avid joins the cloud with Stream IO
While Adobe has Frame.io, rival Avid now offers Stream IO, a flexible, software-based platform for production ingest and playout with a subscription model. It can be configured to ingest or play out IP streams and SDI streams, letting teams migrate from legacy workflows to cloud and IP. There is support for most popular video formats, codecs and resolutions. Avid Stream IO supports common production formats like SDI, compressed IP streams - SRT, RTMP, NDI – with SMPTE 2110 due later this year. It is compatible with 1080p, UHD and HDR content. avid.com
