1 For zooming when using auto focus. Manual focus is not supported.
2 Use large f number when shooting with open aperture at minimum focusing distance to prevent image quality deterioration at corners.
3 Manual focusing only. The Control Ring operation is not supported.
4 "S-MRS Magnet Ring" is necessary for each of the Control Ring, Focus Ring and SA Control Ring of "RF100mm f/2.8 L MACRO IS USM". Prepare enough "S-MRS Magnet Ring" for each Ring you use underwater.
5 It is recommended to always enable lens profile correction for RAW images, etc. as disabling the feature will have vignetting and significant optical vignetting when shooting macro. This issue occurs between the camera and the camera lens, and is not caused by the port.
