It may focus close, but it is awkward as a close-up lens anywhere but in a studio setting. Even using a macro rail I found that with the shortest tubes the distance from the front element to subject is terribly close, and forget longer tubes period. I think brightcolors has the best replies here. I certainly wouldn't recommend it as a closeup lens because of the focal plane to front element distance combined with minimum focus, it is just difficult to use. I prefer just using my ts-e 90 and tubes, and then pan-and-stitch if I want a larger composition for closeup since it is so easy with macro rail on panorama base.
