I am the first kid on my block to get the new ten stop Tiffen 3.0 netrual density filter. This one fits the Olympus 12-40 (62mm) for the OMD-M1. The M1 has this incredible feature (livebulb) where long exposures display on the camera as they build up during the exposure. I can't wait for the opportunity to use this very dark piece of kit on some water shots. I also obtained a 1.2 (4 stop) filter for less dof during the day.
