Hi I don't know if I'm asking an impossible question, but it has to be worth a try... I'm interested in buying a second hand EOS 300D (that's the digital rebel to some people) that I've seen for sale here in the UK. I wanted to get an idea of how 'used' it actually is. Taking a trial photo in the shop didn't reveal a frame count, but it did label the filename as 6031.jpg. I'm guessing some likely possiblities are: (a) that the camera has taken 6031 shots (b) that the '6' represents the picture resolution, i.e. the maximum of 6.3 megapixels, and that the camera is therefore likely to have taken only 31 shots (c) that numbering restarts every time a memory card is wiped, in which case the camera has taken 31 shots since the last wipe. But does anyone know for sure how the 300D labels its filenames and if I can deduce frame count from it? I realise that I won't get an absolute definite answer, but if, for example, someone could confirm what the '6' stands for that would certainly give me some clues and enable me better to judge the value of this camera. Any suggestions appreciated. Dan
