Sigma FF High Speed Prime 24mm T1.5 E-Mount

The Sigma Cine Lens 24mm is a part of the FF-High-Speed-Prime-Line. The lineup ranges from 14mm to 135mm, and covers T1.5 to T2. The lenses are compatible with full frame, and while being more compact, it can offer superior resolution than other high­-end prime sets do. With the seven prime lenses from FF High Speed Prime Line, there is no need to change the lighting to shoot a variety of cuts, and it is possible to meet the demands that professional movie creation requires.

6K-8K class resolution
The lineup features the same optical system that delivers 50-megapixel plus resolution in still photography. Therefore, these lenses are ready for higher resolution shooting, and are ideal for chroma keying as well.

Minimization of flare and ghosting
Computer-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 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.

Color balance standardized across the lineup
All of the lenses in the lineup are designed to comply with SIGMA's CCI standard. Standardized color balance makes color correction a snap.

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.

100% metal body
The body is made completely of metal to stand up to tough professional use over the long term.

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.

Laser engraving for enhanced durability
Information on each ring is laser-engraved for use over the long term. In addition, tape may be placed on gradations without fear of stripping away the paint when the tape is removed.

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.
