I have had an Olympus EP1 for over two years, and I love the camera. I use prime lenses with it, mostly: a Panasonic f1.7 20mm pancake, and the Olympus 45mm, both made for the M4/3rds/CSC camera. Until now I have been quite happy without a flash unit, as the low light capability of the 20mm lens with the camera settings is extremely good. I also felt that £175 was a lot of cash to spend on the F14 unit. So when I saw that the flash unit was being sold (discontinued item?) at £75 I felt it was the time to buy. It's fine for me and my purposes with this camera, for now, but this is not (as I understand it) a top-rank flash unit, but it is light and styled to go with the Pen range. At this price it's a four star buy.
