SIGMA MOUNT CONVERTER MC-11

A new device that expands the possibilities of lenses,
making them more valuable than ever.

The new MOUNT CONVERTER MC-11 allows you to use your SIGMA SA mount and SIGMA EOS mount interchangeable lenses with the Sony E-mount camera body.
Until now, the market has seen the introduction of many methods for using lenses from one camera system with a body from a different system. In the digital age, however, camera systems have become much more complex, and it is challenging to create a mount converter that aligns both the mechanics and software of the lens and body. Creating a converter that matches lenses for current DSLRs to bodies for mirrorless interchangeable-lens camera systems is even more challenging. Now the market demands a converter that goes beyond simply aligning the flange back distance to retaining full functionality.
MOUNT CONVERTER MC-11 incorporates the digital data necessary to provide fast and smooth AF for compatible lenses as well as OS features and functions of the camera that help control peripheral brightness and correct transverse chromatic aberration, distortion, and more.
In addition, since Sony E-mount camera bodies do not require mechanical integration with lenses for aperture control, the MOUNT CONVERTER MC-11 makes SIGMA SA mount interchangeable lenses and SIGMA interchangeable lenses for Canon cameras fully compatible with the automatic exposure control of Sony E-mount camera bodies.

MOUNT CONVERTER MC-11 is ideal for professional photographers who use different camera systems depending on the subject, as well as amateur photographers who enjoy using a variety of camera systems. Increasing the compatibility of lenses with different camera systems makes these assets more valuable than ever. In addition, users of Sony E-mount camera bodies will enjoy an immediate increase in the number of lenses available to them.

More flexible use of valuable lens assets

With the MOUNT CONVERTER MC-11, users of SIGMA SA mount interchangeable lenses and SIGMA EOS mount interchangeable lenses for Canon camera bodies* can use them as is with Sony E-mount camera systems. Users of multiple mounts will enjoy more flexible use of their valuable lens assets.
* Please see lens compatibility chart below

35 interchangeable SIGMA lenses available*
for Sony E-mount camera bodies

The MOUNT CONVERTER MC-11 gives Sony E-mount camera body users access to a total of 35 SIGMA interchangeable lenses. Thanks to compatibility with auto-image area setting functionality, SIGMA DC lenses for APS-C sensors can be used with camera bodies with full-size sensors without the need for any special operation.
Compatible SIGMA DC lenses can therefore be freely used with Sony E-mount camera bodies.

Easy-to-use interface

Green light:
the lens is compatible.
Blinking green light:
the lens firmware needs to be updated using the SIGMA USB DOCK.
Blinking orange light:
the lens is compatible but the MC-11 requires an update to retrieve new lens data.
Not lighting up:
the lens is not compatible

The LED display on the MOUNT CONVERTER MC-11 makes it easy to know whether an attached lens is compatible or not and whether the mount converter control data needs to be updated for operation with that lens.

Includes necessary data

MOUNT CONVERTER MC-11 incorporates the data necessary for each compatible lens and uses a dedicated control program to optimize AF drive, aperture control, and other functions. It is compatible with functions of the camera that maintain peripheral brightness and correct transverse chromatic aberration, distortion, and more. As new compatible lenses are released, control data for MOUNT CONVERTER MC-11 can be updated via a personal computer.
Note: Lens data updates require the installation of the latest version of SIGMA Optimization Pro on your personal computer.

Other features

Compatible with optical stabilization features of both lens and camera body

The compatibility of MOUNT CONVERTER MC-11 with the OS features of both the lens and the camera body makes possible superior correction of camera shake and other stability issues. When used with a camera body that features an OS function, MOUNT CONVERTER MC-11 allows angle shake correction in the lens for superior corrective performance.

Flocking inside barrel helps prevent internal reflections

MOUNT CONVERTER MC-11 features flocking in its interior to help prevent internal reflections and a reduction in lens performance.

Compatibility with Exif data

Lens type, focal length, F number, and other tags are embedded as Exif data in the image file.

SIGMA MOUNT CONVERTER MC-21

The new mount converter
enhancing
the extensibility
of the L-Mount system.

The SIGMA MOUNT CONVERTER MC-21 allows SIGMA SA mount and SIGMA’s CANON EF mount interchangeable lens owners to use their lens investment on L-Mount camera bodies. The converter allows more freedom of choice for L-Mount cameras, enhancing the extensibility of the L-Mount system.

Available AF mounts: SIGMA SA-L、CANON EF-L*1
Barcode: SIGMA SA-L 00-85126-93724-9, CANON EF-L 00-85126-93723-2

Note: The appearance and specifications are subject to change without notice. *1 SIGMA’s CANON EE mount compatible lens
* SIGMA's CANON EF mount compatible lens

Effective use of lens investment

Attaching the MC-21 to your collection of SIGMA SA mount and SIGMA’s CANON EF mount compatible lenses* allows them to be used as L-Mount system lenses, promoting the effective use of valuable lenses already owned.

* See the list of compatible lenses below.

32 interchangeable lenses available
to be used for L-Mount cameras

The MC-21 increases the number of interchangeable lenses manufactured by SIGMA that can be used with the L-Mount system by 32 lenses. Compatible with the autocrop function, mounting APS-C size image circle DC lenses to a camera body equipped with a 35mm full size sensor still allows immediate use for shooting.

Simple interface

Green light: the lens is compatible
Orange light: the lens is compatible*
Not lighting up: the lens is not compatible

Whether the mounted lens is compatible or not is instantly visible from the color and the on/off of the MC-21's built-in LED. The LED also notifies the user when a lens firmware update is available.

* The lens requires firmware update.

Lens data is pre-loaded

Running the data pre-loaded in the MC-21 for each lens by the special control program, autofocus and aperture control have been optimized. Regarding lenses to be released in the future, data for operating these lenses via the MC-21 will be stored in the lens. It means no firmware updates of the MC-21 will be required to use those new lenses. In addition, the MC-21 also supports correction functions of camera such as peripheral illumination, chromatic aberration of magnification, and distortion.

Other features

Fast and accurate auto focus

High precision AF photography in AF-S mode is achieved.

Note: Not compatible with AF-C mode.

Comes with a tripod socket

Equipped with a socket for attaching the tripod*. Lenses not equipped with a tripod socket can be used by mounting the tripod to the MC-21.

* The tool supplied makes attaching/detaching possible.

The inside surface of the barrel is covered with flocking to eliminate internal reflections.

To prevent a reduction in lens performance due to internal reflections, the inside surface of the barrel is covered with flocking.

Inclusion in Exif data

Information such as lens type, focal length, F number, and other tags are embedded as Exif data in each image file.

Notice on usage of the SIGMA Mount Converter MC-21 when it is used in combination with Panasonic’s LUMIX S1, LUMIX S1R, and LUMIX S1H
Only AF-S works in Autofocus Mode. AF-C cannot be selected.
The Auto continuous operation cannot be used during video shooting.
Touch AF cannot be used.
With lenses incorporating MO (Manual Override), operation in manual mode is possible only after focusing.

Compatibility with other cameras
When we announced the MC-21 on February 26th, 2019, we mentioned that it was compatible with cameras manufactured by Leica Camera AG. However, specification changed and it will not be compatible with Leica’s existing L-Mount cameras. We sincerely apologize for the inconvenience this situation may have caused.
