信息

SIGMA MOUNT CONVERTER MC-21允许 SIGMA SA 卡口和 SIGMA 的 CANON EF 卡口可互换镜头所有者将其镜头投资用于 L 卡口相机机身。该转换器为适马、徕卡相机和松下的L卡口相机提供了更多的选择自由，增强了L卡口系统的可扩展性。

1. 有效利用镜头投资
将MC-21安装到您收藏的SIGMA SA卡口和SIGMA CANON EF卡口兼容镜头※上，可以将它们用作L卡口系统镜头，从而促进有效利用已拥有的宝贵镜头。
※请参阅下面的兼容镜头列表。

2. 29 个可用于 L 卡口相机的可互换镜头
MC-21 将 SIGMA 制造的可用于 L 卡口系统的可互换镜头数量增加了 29 个镜头。兼容自动裁剪功能，将APS-C尺寸像圈DC镜头安装到配备35mm全画幅传感器的相机机身上仍然可以立即使用进行拍摄。

3.快速准确的自动对焦
实现AF-S模式下的高精度自动对焦摄影。
* 不兼容 AF-C 模式。

4. 简单的界面
从MC-21内置LED的颜色和开/关即可立即看出所安装的镜头是否兼容。当镜头固件更新可用时，LED 还会通知用户。

5. 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.

● 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.
