I didn't do this on purpose it just happened but you can see how shallow the DOF is .The focus only exists between the thread in front and the thread in the rear of the needle.I guess its not over 2mm.

I went to a lot of trouble to compose that picture.LOL,,,,I stuck the needle in a large Pink Pearl eraser and let the thread just hang from above which was taped to an LED light ring.I used a tripod and a remote release.Fun stuff trying to figure out the setups.

When I shoot macro (or anything else) and want a lot of DOF, I will go as high as F32 to get it. You shot this at f10, want to see some short DOF try it wide open!
