SIGMA Cine Objektiv - 105 mm T1.5 - PL-Mount

Sigma Cine Objektiv 105mm T1.5. Sigma's 105mm T1.5 PL-Mount High-Speed Prime Lens merges their acclaimed Global Vision still line's optics and mechanics with a cinema-focused design. This mid-range 105mm EF-mount prime lens, also available in Sony E and PL mounts, is designed for full-frame sensors, offering 6-8K resolution and a T1.5 aperture in a sleek, lightweight build.

• Covers Full-Frame Sensor Size
• PL Mount
• Aperture Range T1.5 to T16
• Geared Focus and Iris Control Rings
• Clickless Iris Ring, 9-Blade Iris
• Suitable for 8K Image Capture
• Weight 1.6kg
• 95mm Front Diameter

The lens series features a uniform 95mm front diameter and similar physical dimensions, facilitating quick and easy attachment of accessories like matte boxes, follow focuses, and lens control motors. The lens boasts a 9-bladed iris, delivering aesthetically pleasing bokeh while minimizing ghosting and flare. Its color output is standardized to simplify color grading.

Each lens in this series maintains consistent gear positions and a 180° focus barrel rotation. These FF High-Speed Primes are equipped with a smooth, clickless iris marked linearly, silent operation gear ring dampeners, a standard 0.8 module gear pitch, and durable engraved markings. Key markings use luminous paint for visibility in dim conditions.

For added durability and to reduce strain on the camera's lens mount, the lens incorporates a built-in support foot within its dust- and water-resistant metal body.

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.

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.

6K-8K class resolution

The 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.

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 and Splash Resistant Structure

The lineup features the same dust and splash resistant structure 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.

Note: Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

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 the lens in the dark and other tasks. Moreover, new FULLY LUMINOUS versions of the lenses feature the above plus rings whose numbers and gradations are finished with luminous paint.

Laser engraving for enhanced durability

Information on rings and elsewhere is laser-engraved for use over the long term. In addition, tape may be placed on gradations without fear of stripping away paint when it is removed.

Focus Ring with 0.8M gear pitch

Each lens has a 0.8M gear pitch, which is the standard for cine lenses, ensuring compatibility with existing accessories.
