佳能镜头与相机的通信协议

Buying lenses for your camera isn’t always simple. The two major manufacturers, Canon and Nikon, both have different options depending on whether you’re getting a lens for a full-frame or crop sensor camera. Even if you’ve got a Canon camera, you can’t be sure that any Canon lens will work.

为相机购买镜头并不总是那么简单。 佳能和尼康这两个主要制造商都有不同的选择，具体取决于您要使用的是全画幅相机还是作物传感器相机的镜头 。 即使您拥有佳能相机，也无法确定任何佳能镜头都可以使用。

Third parties, like Sigma and Tamron, make things even more confusing. They also make lenses that come with a choice of mount. You can get a Sigma 24-105 for either Canon or Nikon cameras.

像Sigma和Tamron这样的第三方使事情变得更加混乱。 他们还制造带有可选安装座的镜头。 您可以购买适用于佳能或尼康相机的Sigma 24-105。

Let’s break things down a bit and look at what mounts Canon and Nikon are currently using for their cameras and lenses.
