Through use of the T2 to C/CS adapter you can connect many accessories of the common T2 standard to your camera that has a C or CS thread*.
* The C/CS thread is identical. The distinction is that cameras quoting the C thread have 17.5mm backfocus from the thread end to the sensor and for the CS (C Short) it is 12.5mm.
This adapter has an effective length of 4mm excluding the C/CS thread. The C/CS thread is 2mm long.
