Specifically developed to meet the challenges of precision needed for both 3D and 4K cinematography
Meduza Systems, the Mario Award winning producer of the Meduza Camera, will launch the Delta 4K S3D Meduza Lens, the first built for purpose, matched pair, 3D lenses designed by Kenji Suematsu, at the IBC Conference in Amsterdam, Sept. 8-13. The announcement was made today by Chris Cary, CEO of the UK 3D Tech start-up, 3D Visual Enterprises, parent company of the 3D lens and 3D camera developer, Meduza Systems.
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.
The Delta series derives its name from the term “delta” or change present in one image vs. another. Each lens pair is designed to minimize the amount of optical change and at the same time build a lens suited to the world of S3D which is different from the world of 2D. “Quality S3D images are the product of many elements of precise control working together,” says Meduza Systems COO Jon Kitzen, “and optical precision is one of the most vital, especially working in 4K. All of the standards being set for cinema and television alike are reaching out for a level of optical excellence for which 2D lenses and lens mounts trying to work in tandem were never intended.”
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.”
