The lens mount establishes an electronic connection with the camera, allowing lens data to be transmitted (focal length, shooting distance, aperture, etc.). The data that is recorded varies by camera.
Note: This feature is not included on PL mount lenses.
In general, a perfectly parfocal lens production is nearly impossible. SIGMA goes through great lengths to reduce focus shift throughout the zoom range. However, as is the case with most cine zoom lenses, the SIGMA cine zooms are nearly parfocal.
The lenses we have currently launched all have the same front diameter, but their lengths are all different. All of the lenses have the same gear diameter and positions as well. Respective numbers for future lenses are still to be determined.
Yes, SIGMA cine lens mounts may be converted for use with other camera bodies by SIGMA subsidiaries and dealers. Please contact your local SIGMA dealer or service provider for the Mount Conversion Service. Mounts are unable to be converted by users.
The internal mechanism of the SIGMA PL mount cine lenses are very different from EF mount and E mount. Therefore to change the mount, we need to dismantle the whole lens. To guarantee the performance of the lens once dismantled, it requires the same exclusive equipment as building a lens from scratch.
Considering the delivery date and cost, we have not covered PL mount for the mount conversion service.
The SIGMA cine lenses are compatible with SIGMA Mount Converter MC-11, which allows SIGMA lenses with the EF mount to be used with Sony E-mount camera bodies. For further information about this accessory, please click here
Yes, it is the same in order to leverage the outstanding optical performance of SIGMA GLOBAL VISION lenses, which have earned a worldwide reputation for their excellence. The lens cells, aperture mechanical system, and overall optical system are the same as that of the still photo lens of the same focal length.
The new cine lenses each have models compatible with the Canon EF mount, Sony E-mount, and Arri PL mount, allowing them to be used by the main cine cameras on the market. For further information, please click here.
Our cine lenses feature a completely updated mechanical system. We have also given them a choice range of functions to optimize them for modern cinematography. Further, each of our cine lenses features dust- and -splash-proof construction and larger angles of rotation for the iris, focus, and zoom rings.
SIGMA cine lenses have the resolving power needed to make them fully ready for 6-8K shooting, as well as a design that minimizes ghosting and flare. The lineup also includes models that offer full-frame image sensor coverage. SIGMA cine lenses combine outstanding image quality and compactness in a way that truly distinguishes them from competitors.
We plan to launch the 18-35mm and 50-100mm zoom lenses for the Canon EF mount and Sony E-mount in Japan and the US by the December, 2016. The launch dates for an additional zoom lens and five prime lenses are still to be determined.
