当佳能发布采用1.5英寸感光元件的G1X时,许多人还猜测佳能未来微单相机的感光元件尺寸是不是就以1.5英寸为标准,不过随着EOS-M的正式发布,流言终结了。EOS-M系统采用APS-C画幅,感光元件尺寸与佳能的APS-C画幅数码单反相机相同,均为22.3mm×14.9mm,焦距系数为1.6x,而法兰距则仅有18mm(与索尼E系统相同),采用全新的EOS-M卡口,对应专用的EF-M镜头,通过转接环可以兼容EF或EF-S镜头并自动对焦。作为最后一家进入微单领域的主流数码相机厂商,佳能的EOS-M的出现多少透着一丝不
When Canon released the G1X with a 1.5-inch sensor, many also speculated that Canon’s future single-camera sensor size was not based on a 1.5-inch standard, but with the official release of EOS-M, the gossip came to an end. The EOS-M system uses the APS-C format. The dimensions of the sensor are the same as those of Canon’s APS-C format digital SLR cameras, both 22.3mm × 14.9mm with a focal length factor of 1.6x and a flange distance of only 18mm (with Sony E system), with a new EOS-M mount, corresponding to a dedicated EF-M lens that is compatible with EF or EF-S lenses and automatically focuses through the adapter ring. As the last one to enter the mainstream micro-single-digital camera manufacturers, Canon’s EOS-M appears a trace of how little
