Inon MRS Magnet Ring Olympus 50 Set
The INON unique "MRS system" uses magnetic attraction to rotate lens barrel for manual focusing like as land operation of a camera. The MRS system does not use mechanical gear for smooth manual focusing with minimum torque which is great advantage in macro shooting. The "MRS system" is free from a drawback of conventional underwater housing to operate a macro lens having large extension amount by a small control dial. Olympus E system user can benefit this very well established "MRS system".
This magnet ring set can be used with "Inon MRS Olympus 50 Port (with MRS Control Ring)" which is sold separately.
