For photographers who want to make macros only occasionally, or travel a lot (and therefore attach importance to easy manageable luggage) is the intermediate ring the optimal solution, provided they have the XF 35mm 1.4 with which a good magnification of approximately 1: reach 2 leaves. However, the shooting distance is only a few centimeters. Sharpness and resolution are in this appearance at close range surprisingly good. In conjunction with the MCEX-16 And one more advantage: the intermediate ring is light and takes up less space than the only macro lens from the XF series, the 60mm 2.4. I have my 60mm 2.4 sold again, partly because the imaging performance is only slightly better than the combination described. With other lenses of the XF series, the intermediate ring also works well, but is achieved here not so strong magnification.
