Sigma 40mm T1.5 FF Fully Luminous High-Speed Prime Lens for Sony E, Feet

SIGMA CORPORATION has entered into the cinema lens market with the release of its SIGMA CINE LENSES, designed specifically for cinematography. In the world of digital film production, there is an increasing demand for higher resolution, and SIGMA's new lineup of high-performance lenses is compatible with the latest, high-resolution digital cinema cameras. SIGMA has developed its own production system by establishing the required technology for mass production of high-performance lenses for ultra-mega-pixel shooting.FF HIGH SPEED PRIME LINEThe lineup ranges from 20mm to 85mm, and all five lenses are T1.5. They are compatible with full-frame sensors and, while being more compact, can offer superior resolution than other high-end prime sets do. With the five prime lenses from FF High Speed Prime Line, there is no need to change the lighting to shoot a variety of cuts. These lenses bring a consistent level of light to the production and offer greater consistency with regards to the film's look and color/contrast before it enters post-production.• 180 Degree focus throw• Resolution matching up to 8K• Standardized essentials: Gear Position, 95mm Front DiameterEach CINE lens model is weatherproof and has luminous paint markings to aid in changing and operating the lens in the dark. It touts a long focus rotation of 180 degrees and is guided by cams for smooth operation and accuracy. The CINE lens design features standardized essentials such as an 82mm front for ND filters and a 95mm front diameter for matte box use and standard gear positions for accessories like follow focus. They also include a manual linear iris control and electronic mounts that provide vital camera metadata. Each lens is manufactured and inspected in the Sigma factory located in Aizu, Japan.IMAGE QUALITYInspecting each and every lensThere are three requirements for outstanding lenses: Fine design, precise manufacturing and inspection that ensures compliance with all specifications. SIGMA lenses are born of outstanding design concepts and excellent manufacturing technology, but they are not complete until they undergo their uncompromising lens performance evaluation. SIGMA has developed their own A1 proprietary Modulation Transfer Function (MTF) measuring system using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of their quality control inspections. Each and every lens is checked before shipping. Thanks to the ultra-high resolution sensors, high- performance shooting is assured.Minimization of flare and ghostingComputer-based ray tracing has been used from the design stage onward to minimize flare and ghosting and enhance contrast in backlit conditions. Ghosting has also been checked at every prototype stage, with its causes identified, assessed, and eliminated.Sharpness combined with outstanding bokeh effectTo fulfill the high demands for image quality in still photography, SIGMA has solved a wide range of issues. The benefit of these efforts can now be enjoyed in cine lenses as well.Color balance standardized across the lineupAll of the lenses in the lineup are designed to comply with SIGMA's CCI standard. Standardized color balance makes color correction a snap.6K-8K class resolutionThe lineup features the same optical system that delivers 50-megapixel or higher resolution in still photography. These lenses are therefore ready for higher-resolution shooting and are ideal for chroma keying as well.BUILD QUALITYLightweight and compactLeveraging the high-precision, high-efficiency mass production technologies developed for its still camera lenses, SIGMA has made extremely lightweight and compact cine lenses a reality. Featuring all functions essential to cinematography, these lenses keep weight and size to a minimum, while their specification is optimized for enhanced durability. The end result is a combination of performance and compact design at the highest level.Dust-proof and splash-proof constructionThe lineup features the same dust-proof and splash-proof construction as the SIGMA 150-600mm F5-6.3 DG OS HSM|Sports. With each ring and mount specially sealed to prevent water and dust from entering, this lens is ready for use in tough conditions. The unusually robust specification of the lineup allows the user to concentrate on shooting while significantly reducing the burden of maintenance.Luminous paint for enhanced visibilityThe specification, graduation baseline, and lens change indications all feature luminous paint to aid in changing the lens in the dark and other tasks. Moreover, new FULLY LUMINOUS versions of the lenses feature the above plus rings whose numbers and graduations are finished with luminous paint.Laser engraving for enhanced durabilityInformation on rings and elsewhere is laser-engraved for use over the long term. In addition, tape may be placed on graduations without fear of stripping away paint when it is removed.ROBUST ACCESSORY SELECTIONEach accessory is available separately. The USB DOCK allows the user to connect the lens to a computer and update firmware, while the MOUNT CONVERTER MC-11 allows users to enjoy the high performance of SIGMA's Canon EF mount interchangeable lenses with the Sony E-mount camera body. These and other accessories further enhance the convenience and ease of use of the new lens lineup. lenses come complete with a conventional cine-style front lens cap.MOUNT CONVERSION SERVICESeeing lenses as valuable assets, SIGMA now makes the Mount Conversion Service available for its new cine lenses. Successfully implemented for their still photography camera lenses, this service allows users to convert their lenses to and from EF and E-mounts (charges apply). If the camera system changes, it is possible to simply convert the mount system to continue using the high-performance SIGMA lenses.Note: The Mount Conversion Service is not available for PL mount lenses.
