Today’s announcement of the new Sigma High Speed Cinema lenses, complete with both prime and zooms, comes on the eve of the International Broadcasters Convention (IBC) week in Amsterdam. Sigma’s Art series has long been a favorite of DSLR filmmakers, and these new cinema lenses are aimed squarely at the high-end commercial and film industries. This is the company’s first foray into the cinema lens world, and is an ambitious first step with eight new lenses covering a variety of focal lengths. The Sigma FF High Speed Cinema Prime lineup includes the following focal lengths: 20mm, 24mm, 35mm, 50mm and 85mm, all at a speedy T1.5, with the option of E, EF or PL mounts. Two new Sigma High Speed Cinema Zooms cover 18-35mm and 50-100mm at T2.0, and will handle 6-8K sensors from camera manufacturers like RED Cinema. Available initially in both EF and Sony E mount, I’m told PL mounts are on the way for the zoom line as well. All lenses are weatherproofed and use luminous paint markings for operating in dark conditions. Sigma also announced a plan to continue adding to the cinema line throughout 2017 with an additional zoom and a further five primes on the horizon. New Sigma High Speed 50-100 T2.0 Cine Zoom (EF and Sony E) Sigma High Speed Cinema Lenses – Features at a Glance: Sigma FF High Speed Primes in T1.5, and Full Frame compatible. Sigma High Speed Zooms in T2, Super 35mm coverage. Metal bodies, with standardised 95mm front diameter, 82mm filter thread, lens gear positions and 0.8M gear pitch across the board. Same weatherproofing found in their 150-600mm F5-6.3 DG OS HSM Sports Zoom. Luminous paint and laser engraved ensure durable lens markings that can be operated also in dark conditions. Smooth and precise focusing and zooming with ring throw of 180° and 160°, respectively. Optional manual iris control. Separately, Sigma also announced a non “High Speed” FF Cinema Zoom today that covers 24-35mm T2.2, and will be available in EF and E mount with no plans for a PL mount version. Could this be a more budget friendly option aimed at competitors like Zeiss with their ZEISS LWZ.3 21-100mm/T.2.9-3.9 T recently being announced? With Rokinon’s Xeen line occupying the entry level of the cinema glass market at least in terms of primes, and with many manufacturers building glass only big-budget productions can afford, it will be interesting to see where Sigma’s pricing lands. Availability: Expected Q4, 2016 – initially only available in Japan and the United States. Pricing: TBD What are your thoughts on the new Sigma FF High Speed Cinema lineup? Let us know below.Read more

Metabones just published a firmware update for their latest Canon EF to Sony NEX Smart Adapter (Mark IV) that addresses some of the issues people have had when using the Sony A7S. The Sony A7S is a great video camera we all like to use, yet many require an adapter to be able to use their Canon lenses. The Metabones mark IV is the latest version of their famous electronic adapter that allows you to control aperture and use image stabilization with digital lenses and most importantly works with the A7S’ full frame sensor. The issues we’ve encountered at cinema5D mostly concern manual lenses that would crash the Sony A7S and force you to remove the battery or cause other errors when using the camera. Unfortunately this firmware doesn’t seem to fix those issues. There’s a temporary manual fix though, that we will talk about later. The firmware updates can be undertaken by yourself.
