The Hexar AF is a superb camera, and for the quality of the photos it produces, it is a bargain. The date feature can be turned off, or you can simply remove the battery from the back. I have a couple of Hexars with data backs, and have had no trouble turning them off.
I've collected a few Hexars, black, Silver, and Rhodium. The finish is not important, but I can't pass up a Hexar if I find a good deal on one.
