Sigma 40mm T1.5 FF High Speed Prime Cine Lens - E Mount

40mm T1.5 Full Frame High Speed Prime Cine Lens from Sigma

Ranging from 20mm to 85mm, the entire lineup is T1.5. These prime lenses are compact, offer full-frame compatibility, and rival high-end prime sets with their superior resolution. Allowing users to shoot a variety of cuts without lighting changes, the FF High Speed Prime Line meets all the demands of professional movie creation.

Inspecting each and every lens
There 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.

Luminous paint for enhanced visibility
The specification, gradation baseline, and lens change indications all feature luminous paint to aid in changing and operating the lens in the dark.

Sharpness combined with outstanding bokeh effect
To 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.

Lightweight and compact
Leveraging 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 construction
The 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.

Silent ring stoppers
The stopper of each ring incorporates a damper made of a special resin, resulting in silent operation. While offering a satisfying lock feel, this feature eliminates any metallic sounds, allowing the user to shoot with confidence in a quiet area.

Linear iris ring
The linear iris ring gives users the same rotational angle per T-stop for direct, intuitive control.
