There have been some ludicrously cool camera features over the years, but I don't think I've ever seen one quite as cool as this: the Live GND filter.
Though when I think about those other features – things like 5-axis in-body image stabilization, high-resolution pixel-shift shooting, Live Composite bulb mode, in-camera focus bracketing, pre-capture when half-pressing the shutter, software-driven neutral density filters – they share something in common with this new one: they were all invented by Olympus / OM System.
