I'm wondering if others with Olympus cameras (e.g., E-PL5 and OM-D) have as much problem as I do in the way Olympus establishes its file naming system. The default is "Pmdd0000" where m=month and dd=date. Olympus then assigns a consecutive number to 0000, except I just discovered that the numbers don't go up to 9999. They go up only to 0999, and then start again at 0001. I changed my file name to "OLY_0000" only to discover that I need to change the name after shooting 999 frames. I'm curious to know what others on this forum use as your file naming system? Are you satisfied with the default file naming?
