I think this is Andrea haemorrhoa, but if someone knows better, I would like to know. Either way, is was fairly active, in a plastic box, and I was truing to chase it around with a manual macro lens. It took a long time, and a lot of frames to delete. Whilst on this subject, does anyone know why the ED 18-180 lens, and some others, do not work reliabily with the EX25. Sometimes it works, but most times it goes into a hunt mode, going from one side of focus to the other side of focus. It looks the hardware can do the job, but the firmware is a bit dodgy. Olympus state that the EX25 and the ED18-180 do not autofocus, so it is not a fault as such.
