1. "Autofocus": The G2 features a high-speed, precision autofocus system, which is a notable improvement over manual focusing systems found in many cameras of its time.
2. "Lens Compatibility": The G2 is designed to use Contax G-series lenses, which are known for their exceptional build quality and optical performance. These lenses offer a range of focal lengths and apertures, providing photographers with a wide variety of creative options.
3. "Body Design": The G2 has a sleek, compact body with a magnesium alloy construction, which makes it lightweight yet durable. The camera features a pentaprism viewfinder with a large, bright image, which is essential for accurate composition and focusing.

康泰时(contax)G2是旁轴联动测距相机中的一个里程碑,它是由蔡司和京瓷合作在日本复活康泰时品牌之后在1994年推出的世界上第一部自动对焦可更换镜头旁轴相机G1的后继产品。以G1为初代的G系统包括先后两代机身和6只定焦1只变焦一共七只镜头,包括1994年伴随G1推出的T* hologon 16mm/f8,T* biogon 28mm/f 2.8,T* planar 45mm/f2,T* sonnar 90mm/f2.8,1996年伴随G2推出的T* planar 35mm/f2,T* 21mm/f2.8,最后还在1999年推出了一支在旁轴上很少见的变焦镜头Vario sonnar T* 35-70mm/f3.5-5.6,这些镜头的素质经过长久以来用户和爱好者们的验证。



G2的自动对焦系统设计的很有意思,采用了主动对焦和被动对焦相结合的工作模式,在光线暗淡的地方,G2会发出一束肉眼不可见的红外线来辅助对焦,在旁轴相机经常面临的恶劣拍摄环境中,这种对焦方式无疑具备很高的实用价值。G2的取景器采用了和传统的联动测距系统略有差别的开普勒实相变焦取景系统,相机可以在使用28-90mm镜头时自动切换补偿视差,免去了使用者的一个大麻烦。G2的测光系统主要是中央重点测光,不同于单反的是,它是对涂在快门幕帘上的一块18%灰来测量反射光的,所以G2的测光非常准,比一般的单反相机要准很多。
