蔡司与京瓷合作生产的康泰时照相机有着种类繁多的Y/C卡口可交换镜头。Y/C的意思表示Yashica/Contax,即雅西卡(蔡斯早先的日本合作伙伴,日后被京瓷收购)与康泰时的首字母缩写,也可以称之为C/Y卡口。以下仅列出Carl Zeiss品牌的镜头。

自Y/C卡口的Carl Zeiss镜头诞生以来,便一直存在着德国产的镜头与日本产的镜头有无区别的争论。这类争论在2001年左右达到最火热的状态,又随着数码相机的普及与Contax渐渐淡出市场而平息。目前公认的结论是:除了年代跨度较大的一些批次(85mm/F1.4就是一个例子)存在较不明显的区别外,其他镜头无论光学性能还是做工质量,德产日产间均无明显区别。
