Meduza Launches the Delta 4K S3D Lens at IBC 2011

The Delta 4K S3D Meduza lens set has been designed and built to deliver super high precision, not only in the glass, but also in the motorized focus and iris controls. The lenses of the series are not only uniquely optically matched and sold in pairs, but each lens has been constructed to fit into a compact 38mm wide mechanical barrel to allow for very close inter-axial positioning that is critical to S3D.   “As part of Meduza’s continuing ambition to push the boundaries of excellence, the Delta series has been specifically developed to meet the challenges of precision needed both for 3D and for 4K cinematography,” says Cary.

Meduza set out to redefine the 2D optics that have previously been rather large, heavy, bulky design film lenses, never built to the tolerances of S3D use.  While a lens may indicate 50 mm, in reality it may be a 48.5 mm and the next lens a 49.9mm. Colour and distortion from one lens to the next could also be quite far off. All of this creates added work and costs in post-production.  Most importantly, larger format film lenses are just not capable of the resolution requirements of the new generation of small compact 4K sensors, therefore, not optimal for S3D work.

The 16 piece optical set has been designed specifically to accommodate motorised focus and iris controls.  The iris and focus rings, which float on a set of 50 micro ball bearings will be supported by the forthcoming Preston 3D controller. 

Kenji Suematsu’s new Meduza Mount is designed to deliver precise optical positioning in relation to the sensor.  “We found the C mount and other fittings just weren’t able to work within the tolerances we set,” said Cary.  “The standards required for 4K and S3D are far more demanding so we built for tomorrow rather than settle for today.”

Key Features of the Delta 4K S3D Meduza Lens:

• 8 focal length pairs 16 lens set (1.9/35mm, 1.4/23mm, 1.4/17mm, 1.4/12mm, 1.9/10mm, 1.4/8mm, 2.1/6mm, 1.8/4.8mm)

• Designed specifically for motorised control

• Delivers more than 170 line pairs of resolution

• Optics matched to 3 decimal places of focal length

• Suitable for use with 2/3’’ or smaller sensor cameras such as Silicon Imaging, Iconix and Flare

• Focus & Iris floating on 50 micro ball bearings

• Small, lightweight, compact at just 38mm for side by side rigs and in the Meduza camera

• Unique Meduza mount  for absolutely accurate focal positioning of lens to sensor centre.

MEDUZA SYSTEMS
3D Visual Enterprises Ltd, the UK based holding company, was established specifically to service the growing demand within the professional film and television community for a complete and technically advanced 3D image capturing system.  Meduza Systems was created to develop an imaging system that would solve the single camera problem within an architecture that could be constantly upgraded to keep pace with the growth of the industry and advancing technology.   The system had to be versatile, flexible, capable of being upgraded and adapted to match the pace of developing sensor and optical technology and to deliver visual images at the highest resolution possible at all times.  The Meduza was designed to fill the void in the market with compatibility in all of the production environments and in any industry, from Giant Screen 15/70, to live events, to hand held natural history productions.  Above all, the company’s mission is to create a stereoscopic digital 3D camera that would never be obsolete and that could constantly strive to meet the growing and changing needs of its customers.
