Name: Macro Ring Macro extend the ringRole: the lens to macro photographyUse: connect between the lens and adapter ringFeatures: smoothMaterial: High quality aluminum matting oxidative all blackColor: black and silverSpecifications: Thread 25.4mm (1 inch)The role of: A. The conversion effect: increase in a C-CS ring to the C interface to convert CS mount lens B. increase the action at a distanceLens C interface and CS interface simple distinction:Classification of all the camera lens are threaded port, the CCD camera lens mount, there are two industry-standard C mount and CS mount lens mount. Both the threaded portion of the same, but both the distance from the lens to the light-sensitive surface. Two main lens mount standard, C-mount and CS-mount. They have a one inch length of thread and look very similar. Their difference is the distance between the lens to the camera lens to the sensor:CS-mount: the distance between the image sensor to the lens should be 12.5 mmC-mount: the distance between the image sensor to the lens is 17.5 mm. A 5-mm washer (C / CS connection ring) C-mount lens can be used to convert a CS-mount lensesC-mount is the first standard CS-mount its upgrade, the upgrade can reduce manufacturing costs and reduce the sensor size. Now the vast majority of the camera and lens on the market use a CS-mount standard. Can be connected through the use of C / CS ring of an old C-mount lens mount to the camera with a CS-mount interface. If the camera can not focus, it may be because using the wrong type of lens.Note: our special macro ring and the Macro Ring of other family does not like this macro ring can be connected so the C-mount lenses (containing the domestic 50mmF1.4/35mmF1.7 / 25mmF1.4 of Japan and Germany all C-port lens)This is silver.
