I bought an SD card today for one of my cameras, and after I took a few pictures with it I plugged it in to my computer to look at them. I was a bit suprised that my computer recognized the camera as a D40, which it is not, but I thought it might just be a glitch. I opened up the contents of the card, and it turns out that there are indeed already pictures on the card, some taken by a D40, some by some Canon, and the ones I took. There's no indication on the package that it's refurbished or anything. From looking at the pictures, it looks like someone used the card at some sort of seminar, then popped it back in the package. Based on the pictures, I don't think I'll be taking classes from whoever was teaching this one. Here's a sample: Kinda strange eh?
