This is the "GR LENS A12 50mm F2.5 MACRO" camera unit exclusively for the Ricoh GXR. *Note: Although a size option is set for convenience, this is a unit exclusively for the Ricoh GXR. I requested an appraisal at a camera store (Camera Kitamura), but they didn't have a body in stock to check the unit's operation. Therefore, I have not been able to confirm the final operation myself. This item is being sold "as is" without any operational guarantee, so it is offered to those who can perform maintenance and checks themselves, or for parts.
