stole memory card from my camera?? I've been working tech support at a conference all weekend. I went to use my camera this morning and found the SD card missing. I know that, when I took 50 pix the day before the conference, the card was in there (I would not have been able to take pix or play them back without it). The card walked away sometime between Friday evening and Monday morning. There are only two possibilities: 1] I removed the card myself for some completely unknown reason. 2] Someone (a woman - I was the only man within 200 yards of the con) removed the card from my camera (replacing the camera) when I left my pouch unattended. Both of these are unfathomable. I'm hoping to pare it down from two to one possibility. Has anyone heard of a precedent for theft of a memory card?
