ENG-style for cinema lenses
The advent of larger sensor cameras, particularly 4K, has brought a flurry of new lenses, many of which are aimed more at broadcast than digital cinema use
The increasing number of full-frame (24x36mm) DSLR-based cameras, particularly Sony’s compact Alpha 7s low-light 4K model, is attracting a lot of interest, and new lenses.
Cooke is widening its Anamorphic/i lens range. Its new 25mm and 135mm Anamorphic/i lenses are being followed by 80mm and 300mm models, to take its Anamorphic/i range to nine (including 32mm, 40mm, 50mm, 75mm, 100mm: all T2.3). Cooke is also adding a 21mm lens to both the miniS4/i range (which are all T2.8) and the 5/i series (which are T1.4).
With a lens speed of F0.85, the new €1,799 HandeVision Ibelux 40/0.85 is claimed to be the fastest lens for system cameras currently in series production, and ideal for low light. There are versions with Sony E, Fuji X, Canon EOS M and Micro 4/3 mounts.

Fujinon’s A21x7.8 BERM/BERD is “a lightweight 21x lens, but it’s a similar weight to a 18x lens, which is significantly lighter [at 1.6-1.7kg depending on version] than a traditional 22x, so it’s particularly suitable for news and sport,” said Stefan Czich of Fujinon distributor Pyser-SGI, which is showing it at BVE and has had a lot of interest in it from news companies.
MTF Services has worked with AJA to introduce the first lens adaptors for AJA’s Cion camera (which comes with a PL mount). The adaptors include: a Nikon G adaptor with aperture control for both new and old Nikon lenses; an optical system for B4 lenses compatible with any lens with a 2x extender – allowing total sensor coverage with HD B4 lenses as the multi-layer coated optics extend the image from its original 2/3-inch size to cover the Cion’s Super35 sensor while maintaining the original angle of view of the lens; and three adaptors for Canon lenses: Canon FD-to-Cion adaptor for old FD lenses, plus two options for Canon EF mounts. The first is a standard mechanical adaptor, for EF-mount lenses with an aperture ring; the second, a version of the MTF Effect range of adaptors for electronic lenses. When used with the MTF Effect Control Unit it controls the iris in 1/8th stop increments, and powers lens stabilisation and focus (for lenses with powered focus).
Arri’s new Lens Data Encoder LDE-1, part of its Electronic Control System, uses an encoder that delivers data on the position of the lens ring to which it is attached, and can be used with a manual follow focus unit or third-party wireless lens control system. It allows lens data to be generated when an Alexa is used without an Arri lens motor or an LDS lens. Arri has also updated its Wireless Compact Unit WCU-4 to allow easier lens programming, so that lens tables can be generated for any lens, from vintage to modern in less than a minute.
A €350 smart range finder application (cfinder) provides a wireless distance read out when cworld is connected directly to a measurement tool, such as cmotion’s cfinder, Arri’s UDM or Cinetape.
