I just checked a DOF table for a 50mm f1.5 lens, which would have a slightly greater DOF than your f1.0. Even so, the DOF at 3.5 feet is from 3' 51/4" to 3: 61/4". You have less than an inch of subject area that will be in sharp focus. As to the close focus distance, the lens should have an engraved scale that will give the value fairly accurately.
