Auto yes? How much?
Yeah, they pass the aperture info to the camera so you can control the aperture directly from the camera and don't have to stop down to meter. I tried them out last night. I had never used extension tubes before and I hadn't realize just how narrow the min to max focus distance becomes when you use one.
As for the labels, they weren't completely rubbed off when I got them. The 12mm and 20mm labels were partially rubbed off so I finished the job. Then my overwhelming need for symmetry took over and I removed the 36mm label as well
Edit: Just noticed a similar set on ebay. Looks like the labels wore off those as well.
