From Sigma:
 
Thank you for purchasing and using our products.
 
We would like to share the results of our further investigations regarding the operating conditions of the Canon "EOS R" and SIGMA’s interchangeable lenses for Canon mount.
 
When SIGMA’s interchangeable lenses in the current product lineup, listed below, are used in combination with the Canon "EOS R" and their "Mount Adapter EF-EOS R" or "Control Ring Mount Adapter EF-EOS R", both AF and AE operate without any issues. Furthermore, lenses which incorporate Optical Stabilizer (OS) will work with the OS function properly in effect.
 
In addition, when the Digital Lens Optimizer is switched [OFF], but "Peripheral illumination correction", "Chromatic aberration correction" and "Distortion correction", located within the in-camera Lens Aberration Correction function is switched [ON], the appropriate corrections can be achieved in accordance with the optical characteristics of each lens. This is applicable to DG and DC lenses from Contemporary, Art and Sports line listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later. For other lenses, the Digital Lens Optimizer as well as the in-camera Lens Aberration Correction function cannot be used. Therefore, please set all to [OFF] before shooting.

SIGMA 24-70mm F2.8 DG OS HSM | Art
 

• It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.
• It may stop the focus driving from infinity to closer focus distance while shooting video with AF.

SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports
 

• It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.

SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary
 

• It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.
• It may stop the focus driving from infinity to closer focus distance while shooting video with AF.

Other precautions
 

• AF can be used within the area of approximately 80% of the height and width of the sensor surface.
• For interchangeable lenses which are not from Contemporary, Art or Sports line, please focus using MF, since it may be difficult to achieve sufficient focusing speed and accuracy.
• Tele Converters cannot be used together.
• Having the focus mode switch set to MF does not let the lens stored automatically when the camera is turned off.
• Discontinued products have different operating conditions depending on each product and their shipping period. For details, please contact your nearest authorized SIGMA subsidiary / distributor.

Ronkonkoma, NY – December 7, 2018 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, today announced that its anticipated cine lens – Sigma Cine 40mm T1.5 FF – will begin shipping in December 2018 for $3,499.00, with the option to purchase a fully luminous version (FL) for $4,499.00.
 
Sigma Cine 40mm T1.5 FF is a fast and sharp T1.5 cine lens compatible with full-frame camera sensors and optimized for ultra-high-resolution 6K-8K productions. Featuring a 180-degree focus rotation, this lens is available in EF, E and PL mounts with lens support foot and cap included.
 
It is the ninth lens in the Sigma Cine FF High Speed Prime Line. As a standard lens in the cinema industry, the focal length of 40mm has become an essential part of a typical cine prime set. By adding this lens to the Sigma Cine offering, its cine prime set can now satisfy all the demands of professional cinematographers.
 
Sigma Cine 40mm T1.5 FF is the first lens that was designed and developed for the cinema use rather than converting a still photography lens into a cine lens. This development illustrates Sigma’s commitment to the cine market – by always listening to its customers and what their needs are, and now even more than ever with the fully operational Sigma Burbank showcase facility, Sigma strives to develop new products based on that customer feedback.
 
The Sigma 40mm T1.5 FF lives up to the performance standard required by high-end cinematographers as it achieves the highest optical quality as well as consistent rendering performance over the entire image circle. The lens produces one of the best MTF charts ever, making it an excellent choice for all levels of filmmakers.
 
Prominent Characteristics of Sigma Cine Lenses
 

• Individual inspection of every single lens with 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.
• 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.
• Color balance standardized across the line to make color correction a breeze.
• Dust-proof and splash-proof construction, with each ring and mount sealed to prevent water and dust from entering.
• The body is made 100% of metal to stand up to tough professional use over the long term.
• Luminous paint for enhanced visibility
• Laser engraving for enhanced durability
• Mount Conversion 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.
• The Sigma USB Dock allows the user to connect the lens to a computer and update firmware, while the Sigma 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.

Thank you for purchasing and using our products.
 
We would like to announce that, as of this moment SIGMA’s interchangeable lenses for Canon mount in the current lineup do not have any issues with general operation when they are used on the “EOS R”, released by Canon Inc., via their “Mount Adapter EF-EOS R”.
 
In addition, please note the information below when using our lenses.
